Italy enteredWorld War II on 10 June 1940 byinvading France, joining theGerman offensive already in progress. ItaliandictatorBenito Mussolini did so opportunistically as theAllied powers (chieflyFrance and theUnited Kingdom) seemed on the verge of collapse. The Italian war aim was to expand itscolonial empire at the expense of the French and the British. WhileFrance surrendered on 22 June 1940, the United Kingdom and its allies continued to fight far beyond the point which Mussolini had thought possible, ultimately leading to the defeat and dissolution ofFascist Italy in 1943 when Mussolini was deposed in abloodless coup d'état.
Italy'sAxis partner,Nazi Germany, was ready for its defection andoccupied central and northern Italy after thearmistice of Cassibile in September 1943. Afterfreeing Mussolini from captivity, the Germans set him up as the leader of a newpuppet state in the north, theItalian Social Republic. This provokedItalian resistance against the German occupation and also acivil war between pro- and anti-fascist Italians. In the Allied-held south, the Kingdom of Italy officially became aco-belligerent of the Allies and declared war on Germany on 13 October 1943.[1]
The AlliedItalian campaign after theinvasion of Sicily in July of 1943 progressed slowly. The Italian campaign was not given priority in resources in Allied strategical planning as theinvasion of France was considered more important. The mountainous terrain of Italy also aided the defenders and reduced the Allied advantage inmechanized units. Allied victory in Italy did not come until the end of the1945 spring offensive prompted the Axissurrender at Caserta on 28 April 1945, shortly before theend of World War II in Europe in May of 1945. April 25 is celebrated in Italy asliberation day.
Unlike in Germany and Japan, nowar crimes tribunals were held, though the Italian resistancesummarily executed some prominent figures, including Mussolini on 28 April 1945. In the1947 treaty of Pariswith the Allies, Italy agreed to pay 360 million dollars inwar reparations, formally gave up its empire, and lost some national provinces at the frontier with Yugoslavia; the relatively lenient treatment, with Italy avoiding the harsher conditions imposed on Germany and Japan, owed to the post-1943 co-belligerence with the Allies and other factors. The treaty was signed by theItalian Republic, which had replaced the Italian monarchy after the1946 Italian institutional referendum.

During the late 1920s, the ItalianPrime MinisterBenito Mussolini spoke with increasing urgency about imperial expansion, arguing that Italy neededan outlet for its "surplus population" and that it would therefore be in the best interests of other countries to aid in this expansion.[2] The immediate aspiration of the regime was political "hegemony in the Mediterranean–Danubian–Balkan region", more grandiosely Mussolini imagined the conquest "of an empire stretching from theStrait of Gibraltar to theStrait of Hormuz".[3] Balkan and Mediterranean hegemony was predicated byancient Roman dominance in the same regions. There were designs for a protectorate overAlbania and for the annexation ofDalmatia, as well as economic and military control ofYugoslavia andGreece. The regime also sought to establishprotective patron–client relationships withAustria,Hungary,Romania, andBulgaria, which all lay on the outside edges of its European sphere of influence.[4] Although it was not among his publicly proclaimed aims, Mussolini wished to challenge the supremacy of Britain and France in the Mediterranean Sea, which was considered strategically vital, since the Mediterranean was Italy's only conduit to theAtlantic andIndian Oceans.[2]
Mussolini began pursuing his imperial agenda through two colonial wars. Firstly, he successfully and brutally put down therebellions in Italy's Libyan colonies ofTripolitania andCyrenaica, in a long campaign that included the use ofmustard gas, executions and internment camps, and has been described as theLibyan genocide.[5] Then in 1935, Italy invadedAbyssinia, one of the few independent African countries and a soft target, given its army was mostly raised from local tribesmen in the event of war and had few modern weapons. Time was taken to build up overwhelming invasion forces, with the necessary logistical support, to guarantee a clear advantage - in contrast to Italy's unprepared and badly planned entry into World War Two in June 1940.[6] Abyssinia was also a target of immense psychological significance for Italy and its military due to the embarrassing defeat in the1895-1896 war. The trump card of large quantities of modern arms, particularly tanks, aircraft and field artillery, won the day for Italy,[7] and marked a challenge to the established diplomatic order by damaging the credibility of theLeague of Nations and the principles of peaceful negotiations it stood for. Again, mustard gas was used. However, the war did surprise many abroad, given some military experts thought either Italy was not capable of conquering Abyssinia, or it would take much longer.[8]

In 1936, theSpanish Civil War broke out, and Mussolini sent considerable assistance, including a large military force, theCorpo Truppe Volontarie or CTV, to support General Franco's Nationalists, viewing the conflict as an opportunity to replace a democracy with an authoritarian government that might eventually become an Italian client state.[9] Despite an embarrassing defeat at theBattle of Guadalajara, the CTV ultimately evolved into an effective addition to Franco's forces, and it was in Spain that CTV commanders did much to develop the principles of Italy's new military doctrine, 'War of Rapid Decision'.
However, the Spanish Republican forces were a mixed bag in terms of quality, and actions like theBattle of Málaga (where the Italians defeated a force that entirely consisted of poorly equipped militia, with no tanks, anti-tank guns or air support) created an inflated impression in Rome of how effective the Italian military might be in a world war, where they would face better equipped and properly trained opponents. Also, while the war had highlighted the shortcomings of Italian tanks compared to the Russian tanks in the hands of the Republicans, and showed better co-operation was needed between infantry and armour, these issues had not been adequately addressed by the time Italy entered World War II, and remained a problem throughout the conflict.[10]
The aftermath of the war in Ethiopia saw an improvement in German-Italian relations following years of a previously strained relationship, resulting in the signing of atreaty of mutual interest in October 1936. Mussolini referred to this treaty as the creation of a Berlin-Rome Axis, which Europe would revolve around. The treaty was the result of increasing dependence on German coal followingLeague of Nations sanctions, similar policies between the two countries over the conflict in Spain, and German sympathy towards Italy following European backlash to the Ethiopian War. The aftermath of the treaty saw the increasing ties between Italy and Germany, and Mussolini falling underAdolf Hitler's influence from which "he never escaped".[11][12]
In October 1938, in the aftermath of theMunich Agreement, Italy demanded concessions from France. These included afree port atDjibouti, control of theAddis Ababa-Djibouti railroad, Italian participation in the management ofSuez Canal Company, some form of French-Italiancondominium overFrench Tunisia, and the preservation of Italian culture onCorsica with no French assimilation of the people. The French refused the demands, believing the true Italian intention was the territorial acquisition ofNice, Corsica, Tunisia, and Djibouti.[13] On 30 November 1938,Foreign MinisterGaleazzo Ciano addressed theChamber of Deputies on the "natural aspirations of the Italian people" and was met with shouts of "Nice! Corsica!Savoy! Tunisia! Djibouti! Malta!"[14] Later that day, Mussolini addressed theFascist Grand Council "on the subject of what he called the immediate goals of 'Fascist dynamism'." These were Albania; Tunisia; Corsica; theTicino, a canton ofSwitzerland; and all "French territory east of the River Var", including Nice, but not Savoy.[15]
Beginning in 1939 Mussolini often voiced his contention that Italy required uncontested access to the world's oceans and shipping lanes to ensure its national sovereignty.[16] On 4 February 1939, Mussolini addressed the Grand Council in a closed session. He delivered a long speech on international affairs and the goals of his foreign policy, "which bears comparison with Hitler's notorious disposition,minuted by colonel Hossbach". He began by claiming that the freedom of a country is proportional to the strength of its navy. This was followed by "the familiar lament that Italy was a prisoner in the Mediterranean".[a] He called Corsica, Tunisia,Malta, andCyprus "the bars of this prison", and describedGibraltar and Suez as the prison guards.[18][19] To break British control, her bases on Cyprus, Gibraltar, Malta, and inEgypt (controlling theSuez Canal) would have to be neutralized. On 31 March, Mussolini stated that "Italy will not truly be an independent nation so long as she has Corsica,Bizerta, Malta as the bars of her Mediterranean prison and Gibraltar and Suez as the walls." Fascist foreign policy took for granted that the democracies—Britain and France—would someday need to be faced down.[20][21][16] Through armed conquestItalian North Africa andItalian East Africa—separated by the Anglo-Egyptian Sudan—would be linked,[22] and the Mediterranean prison destroyed. Then, Italy would be able to march "either to the Indian Ocean through the Sudan and Abyssinia, or to the Atlantic by way of French North Africa".[15]
In early 1939, while the world was focused on Adolf Hitler breaking the Munich Agreement and occupying parts ofCzechoslovakia, Mussolini turned his sights on the Kingdom of Albania. Italian forcesinvaded Albania on 7 April 1939 and swiftly took control of the small country. Even before the invasion, Albania had been politically dominated by Italy. Once occupied, it was formally made a protectorate of Italy and the Italian king took the Albanian crown. Albania represented a territory Italy could acquire for "'living space' to ease its overpopulation" as well as the foothold needed to launch other expansionist conflicts in the Balkans.[23] Both Mussolini and Hitler were now brazenly flouting international law.
On 22 May 1939, Italy and Germany signed thePact of Steel joining both countries in a military alliance. The pact was the culmination of German-Italian relations from 1936 and was not defensive in nature.[24] Rather, the pact was designed for a "joint war against France and Britain", although the Italian hierarchy held the understanding that such a war would not take place for several years.[25] However, despite the Italian impression, the pact made no reference to such a period of peace and the Germans proceeded with their plans toinvade Poland.[26]

Mussolini's Under-Secretary for War Production,Carlo Favagrossa, had estimated that Italy could not possibly be prepared for major military operations until at least October 1942. This had been made clear during the Italo-German negotiations for the Pact of Steel, whereby it was stipulated that neither signatory was to make war without the other earlier than 1943.[27] Although considered agreat power, the Italian industrial sector was relatively weak compared to otherEuropean major powers. Italian industry did not equal more than 15% of that ofFrance or of Britain in militarily critical areas such asautomobile production: the number of automobiles in Italy before the war was around 374,000, in comparison to around 2,500,000 in Britain and France. The lack of a stronger automotive industry made it difficult for Italy tomechanize its military. Italy still had a predominantly agricultural-based economy, with demographics more akin to adeveloping country (high illiteracy, poverty, rapid population growth and a high proportion of adolescents) and a proportion of GNP derived from industry less than that ofCzechoslovakia,Hungary andSweden, in addition to the other great powers.[28] In terms ofstrategic materials, in 1940, Italy produced 4.4 megatonnes (Mt) of coal, 0.01 Mt of crude oil, 1.2 Mt of iron ore and 2.1 Mt of steel. By comparison, Great Britain produced 224.3 Mt of coal, 11.9 Mt of crude oil, 17.7 Mt of iron ore, and 13.0 Mt of steel and Germany produced 364.8 Mt of coal, 8.0 Mt of crude oil, 29.5 Mt of iron ore and 21.5 Mt of steel.[29] Most raw material needs could be fulfilled only through importation, and no effort was made to stockpile key materials before the entry into war. Approximately one quarter of the ships of Italy's merchant fleet were in allied ports at the outbreak of hostilities, and, given no forewarning, were immediately impounded.[30][31]
Between 1936 and 1939, Italy had supplied the SpanishNationalist forces, fighting underFrancisco Franco during theSpanish Civil War, with large number of weapons and supplies practically free.[32][33] In addition to weapons, theCorpo Truppe Volontarie ("Corps of Volunteer Troops") had also been dispatched to fight for Franco. The financial cost of the war was between 6 and 8.5 billion lire, approximately 14 to 20 per cent of the country's annual expenditure.[33] This was on top of the 12.1 billion lire bill for conquering Abyssinia.[34] Adding to these problems was Italy's extreme debt position. When Benito Mussolini took office, in 1921, the government debt was 93 billionlire, un-repayable in the short to medium term. Only two years later this debt had increased to 405 billion lire.[35]

In September 1939, Britain imposed a selective blockade of Italy. Coal from Germany, which was shipped out ofRotterdam, was declared contraband. The Germans promised to keep up shipments by train, over the Alps, and Britain offered to supply all of Italy's needs in exchange for Italian armaments. The Italians could not agree to the latter terms without shattering their alliance with Germany.[36] On 2 February 1940, however, Mussolini approved a draft contract with theRoyal Air Force to provide 400Caproni aircraft, yet scrapped the deal on 8 February. British intelligence officerFrancis Rodd believed that Mussolini was convinced to reverse policy by German pressure in the week of 2–8 February, a view shared by the British ambassador in Rome,Percy Loraine.[37] On 1 March, the British announced that they would block all coal exports from Rotterdam to Italy.[36][37] Italian coal was one of the most discussed issues in diplomatic circles in the spring of 1940. In April, Britain began strengthening theMediterranean Fleet to enforce the blockade. Despite French uncertainty, Britain rejected concessions to Italy so as not to "create an impression of weakness".[38] Germany supplied Italy with about one million tons of coal a month beginning in the spring of 1940, an amount that exceeded even Mussolini's demand of August 1939 that Italy receive six million tons of coal for its first twelve months of war.[39]

The Italian Royal Army (Regio Esercito) was comparatively depleted and weak at the beginning of the war. Italian tanks were of poor quality and radios few in number. The bulk of Italianartillery dated toWorld War I. The primary fighter of the Italian Royal Air Force (Regia Aeronautica) was theFiat CR.42 Falco, which was technically outclassed bymonoplane fighters of other nations.[40] Of the Regia Aeronautica's approximately 1,760 aircraft, only 900 could be considered in any way combat-worthy. The Italian Royal Navy (Regia Marina) had several modernbattleships but noaircraft carriers.[41]
While there are some examples of well-made, high-quality Italian weapons, such as theBeretta Model 38 submachine gun and the90/53 AA/AT gun (an equally deadly peer of theGerman 88/55), these were exceptions that proved the rule that the bulk of the military's equipment was obsolete and poor.[42] The relatively weak economy, lack of suitable raw materials and consequent inability to produce sufficient quantities of armaments were major reasons behind Fascist Italy's military failures.[43]
On paper, Italy had one of the world's largest armies,[44] but the reality was dramatically different. According to the estimates of Bierman and Smith, the Italian regular army could field only about 200,000 troops at the war's beginning.[41] Irrespective of the attempts to modernize, the majority of Italian army personnel were lightly armed infantry lacking sufficient motor transport.[nb 1] Not enough money was budgeted to train the men in the services, such that the bulk of personnel received much of their training at the front, too late to be of use.[45] Air units had not been trained to operate with the naval fleet and the majority of ships had been built for fleet actions, rather than the convoy protection duties in which they were primarily employed during the war.[46] In any event, a critical lack of fuel kept naval activities to a minimum.[47]
Senior leadership was also a problem. Mussolini personally assumed control of all three individual military service ministries with the intention of influencing detailed planning.[48]Comando Supremo (the Italian High Command) consisted of only a small complement of staff that could do little more than inform the individual service commands of Mussolini's intentions, after which it was up to the individual service commands to develop proper plans and execution.[49] The result was that there was no central direction for operations; the three military services tended to work independently, focusing only on their fields, with little inter-service cooperation.[49][50] Pay discrepancies existed for personnel who were of equal rank, but from different units.
Nazi Germany'sinvasion of Poland on 1 September 1939, marked the beginning of World War II. Despite being anAxis power, Italy remainednon-belligerent until June 1940. Previous conversations between Rome and Berlin on a war against Britain and France had focussed on 1941 or 1942 as a likely start date.[51] So, by going to war in 1939, Hitler had begun a war before Italy was militarily ready - for instance, as late as January 1940, the Italian small arms industry was estimated by the Italian military to have only 13% of the capacity needed to meet wartime demand.[52]
However, Mussolini, while accepting Italy needed more time to re-arm, was dissatisfied with the country's non-belligerent status and wanted a way into the war - on 2nd September 1939, Count Ciano, the Italian foreign minister and Mussolini's son-in-law, wrote in his diary: "The Duce is convinced of the need to remain neutral, but he is not at all happy. Whenever he can he reverts to the possibility of our action."[53]
Following the German conquest of Poland, Mussolini hesitated to enter the war. General SirArchibald Wavell, the head ofMiddle East Command, correctly predicted that Mussolini's pride would ultimately cause him to enter the war. Wavell would compare Mussolini's situation to that of someone at the top of a diving board: "I think he must do something. If he cannot make a graceful dive, he will at least have to jump in somehow; he can hardly put on his dressing-gown and walk down the stairs again."[54]
The exact timing of Italy's entry into the war was greatly influenced by political opportunism, coming at a time when Britain and France were in full retreat during theBattle of France. Mussolini wanted a seat at the peace conference table to make territorial gains, and feared if Italy was not among the victor nations negotiating the post-war settlement then Italy would be viewed internationally as a "second order nation".[55] Mussolini told the heads of the armed forces on 29 May 1940, he feared if Italy entered the war after Anglo-French resistance had collapsed, the Germans would take the view that Italy had only joined in "when the job was done",[56] and thus would be reluctant to share the spoils with the Italians. All this persuaded Mussolini he needed to join the conflict, even though the military were not ready for a conflict in 1940.
There were though long-term causes behind Italy joining the war. Italian Fascists had long felt a sense of grievance towards Britain and France over Italy's disappointing territorial gains from World War One.[57] Also, Mussolini and the Fascists wereirredentists and laid claim to parts of France, as well as Malta which was in the British Empire. It was hoped the war would provide the opportunity to annex these territories.[58]
Aware of Italy's material and planning deficiencies leading up to World War II, and believing that Italy's entry into the war on the side of Germany was inevitable, the British blockaded German coal imports from 1 March 1940 in an attempt to bring Italian industry to a standstill.[59] The British and the French then began amassing their naval fleets, gaining superiority in capital ships over the Regia Marina in the Mediterranean, and sent troops to re-enforce their respective colonial possessions in North Africa.[60][61]
By May 1940, with the Allied situation deteriorating in France, Mussolini was looking for a way into the war that did not place too great a strain on Italy's unprepared armed forces; which led to a lack of consistency in planning, with principal objectives and enemies being changed with little regard for the consequences.[62] Mussolini was well aware of the military and material deficiencies but thought the war would be over soon and did not expect to do much fighting.

On 10 June 1940, as the French government fled toBordeaux during theGerman invasion, declaringParis anopen city, Mussolini felt the conflict would soon end and declared war on Britain and France. As he said to the Army's Chief-of-Staff,Marshal Badoglio:
I only need a few thousand dead so that I can sit at the peace conference as a man who has fought.[63]
Mussolini had the immediate war aim of expanding the Italian colonies in North Africa by taking land from the British and French colonies.
About Mussolini's declaration of war in France, PresidentFranklin D. Roosevelt of the United States said:
On this tenth day of June 1940, the hand that held the dagger has struck it into the back of its neighbor.[64]
The Italian entry into the war opened up new fronts inNorth Africa and theMediterranean. After Italy entered the war, pressure from Nazi Germany led to the internment in theCampagna concentration camp of some of Italy'sJewishrefugees.

In June 1940, after initial success, the Italian offensive into southern France stalled at the fortifiedAlpine Line. On 24 June 1940, France surrendered to Germany. Italy occupied a swath of French territory along the Franco-Italian border. During this operation, Italian casualties amounted to 1,247 men dead or missing and 2,631 wounded. A further 2,151 Italians were hospitalised due tofrostbite.
Late in theBattle of Britain, Italy contributed an expeditionary force, theCorpo Aereo Italiano, which took part inthe Blitz from October 1940 until April 1941, at which time the last elements of the force were withdrawn.
In November 1942, the Italian Royal Army occupied south-easternVichy France andCorsica as part ofCase Anton. From December 1942, Italian military government of French departments east of theRhône River was established, and continued until September 1943, when Italy quit the war. This had the effect of providing ade facto temporary haven for French Jews fleeingthe Holocaust. In January 1943 the Italians refused to cooperate with the Nazis in rounding up Jews living in the occupied zone ofFrance under their control and in March prevented the Nazis from deporting Jews in their zone. German Foreign MinisterJoachim von Ribbentrop complained to Mussolini that "Italian military circles... lack a proper understanding of the Jewish question."[65] Despite this, Fascist Italy by 1940 had become an anti semitic state, having in 1938 passed theItalian racial laws, robbing Italian Jews of civil rights and banning them from many fields of employment.[66]
TheItalian Navy established a submarine base at Bordeaux, code namedBETASOM, and thirty-two Italian submarines participated in theBattle of the Atlantic. Plans to attack the harbour of New York City withCA class midget submarines in 1943 were disrupted when the submarine converted to carry out the attack, theLeonardo da Vinci, was sunk in May 1943.[67] The armistice put a stop to further planning.

Within a week of Italy's declaration of war on 10 June 1940, the British11th Hussars had seizedFort Capuzzo inLibya. In an ambush east ofBardia, the British captured the Italian10th Army Engineer-in-Chief, General Lastucci. On 28 June MarshalItalo Balbo, theGovernor-General of Libya, was killed byfriendly fire while landing inTobruk. Mussolini ordered Balbo's replacement, GeneralRodolfo Graziani, to launch an attack intoEgypt immediately. Graziani complained to Mussolini that his forces were not properly equipped for such an operation, and that an attack into Egypt could not possibly succeed; nevertheless, Mussolini ordered him to proceed.[68] On 13 September, elements of the 10th Army retook Fort Capuzzo and crossed the border into Egypt. Lightly opposed, they advanced about 100 km (60 mi) toSidi Barrani, where they stopped and began entrenching themselves in a series of fortified camps.

At this time, the British had only 36,000 troops available (out of about 100,000 under Middle Eastern command) to defend Egypt, against 236,000 Italian troops.[69] The Italians, however, were not concentrated in one location. They were divided between the 5th army in the west and the 10th army in the east and thus spread out from theTunisian border in western Libya to Sidi Barrani in Egypt. At Sidi Barrani, Graziani, unaware of the British lack of numerical strength,[nb 2] planned to build fortifications and stock them with provisions,ammunition, andfuel, establish a water pipeline, and extend the via Balbia to that location, which was where the road to Alexandria began.[71] This task was being obstructed by BritishRoyal Navy attacks on Italian supply ships in the Mediterranean. At this stage Italian losses remained minimal, but the efficiency of the British Royal Navy would improve as the war went on. Mussolini was fiercely disappointed with Graziani's sluggishness. However, according to Bauer[71] he had only himself to blame, as he had withheld the trucks, armaments, and supplies that Graziani had deemed necessary for success. Wavell was hoping to see the Italians overextend themselves before his intended counter at Marsa Matruh.[71]

One officer of Graziani wrote: "We're trying to fight this... as though it were a colonial war... this is a European war... fought with European weapons against a European enemy. We take too little account of this in building our stone forts.... We are not fighting the Ethiopians now."[72] (This was a reference to theSecond Italo-Abyssinian War where Italian forces had fought against a poorly equipped opponent.)Balbo had said "Our light tanks, already old and armed only with machine guns, are completely out-classed. The machine guns of the British armoured cars pepper them with bullets which easily pierce their armour."[71]
Italian forces around Sidi Barrani had severe weaknesses in their deployment. Their five main fortifications were placed too far apart to allow mutual support against an attacking force, and the areas between were weakly patrolled. The absence of motorised transport did not allow for rapid reorganisation, if needed. The rocky terrain had prevented an anti-tank ditch from being dug and there were too few mines and 47 mm anti-tank guns to repel an armoured advance.[70] By the summer of 1941, the Italians in North Africa had regrouped, retrained and rearmed into a much more effective fighting force, one that proved to be much harder for the British to overcome in encounters from 1941 to 1943.[73]


On 8 December 1940, the British launchedOperation Compass. Planned as an extended raid, it resulted in a force of British, Indian, and Australian troops cutting off the Italian10th Army. Pressing the British advantage home, GeneralRichard O'Connor succeeded in reachingEl Agheila, deep in Libya (an advance of 800 kilometres or 500 miles) and taking some 130,000 prisoners.[74] The Allies nearly destroyed the 10th Army, and seemed on the point of sweeping the Italians out of Libya altogether. Winston Churchill, however, directed the advance be stopped, initially because of supply problems and because of a new Italian offensive that had gained ground in Albania, and ordered troops dispatched to defend Greece. Weeks later the first troops of the GermanAfrika Korps started to arrive in North Africa (February 1941), along with six Italian divisions including the motorizedTrento and armoredAriete.[75][76]
German GeneralErwin Rommel now became the principal Axis field commander in North Africa, although the bulk of his forces were Italian troops, subordinated to the Italian command. Under Rommel's direction the Axis troops pushed the British and Commonwealth troops back into Egypt, but they were unable to complete the task because of exhaustion and their extended supply lines, which were under threat from the Allied enclave atTobruk. After reorganising and re-grouping the Allies launchedOperation Crusader in November 1941 which resulted in the Axis front line being pushed back once more to El Agheila by the end of the year.
In January 1942 the Axis struck back again, advancing toGazala where the front lines stabilised while both sides raced to build up their strength. At the end of May, theGerman-Italian Panzer Army, launched theBattle of Gazala where the British armoured divisions were soundly defeated. The Axis seemed on the verge of sweeping the British out of Egypt, but at theFirst Battle of El Alamein, the Allies halted the Axis advance towards Alexandria. The Axis forces made a final attempt to break through during theBattle of Alam el Halfa, but theEighth Army held firm. After a period of reinforcement and training the Allies assumed the offensive at theSecond Battle of Alamein (October/November 1942) where they scored a decisive victory and the remains of theGerman-Italian Panzer Army were forced to engage in a fighting retreat for 2,600 km (1,600 mi) to the Libyan border with Tunisia.
After the Operation Torch landings in the Vichy French territories ofMorocco andAlgeria (November 1942) British, American and French forces advanced east to engage the German-Italian forces in theTunisia Campaign. By February, the Axis forces in Tunisia were joined by Rommel's forces, after their long withdrawal from El Alamein, which were re-designated theItalian First Army (underGiovanni Messe) when Rommel left to command the Axis forces to the north at theBattle of the Kasserine Pass. Despite the Axis success at Kasserine, the Allies were able to reorganise (with all forces under the unified direction of18th Army Group commanded by GeneralSir Harold Alexander) and regain the initiative in April. The Allies completed the defeat of the Axis armies in North Africa in May 1943.


In addition to the well-known campaigns in the western desert during 1940, the Italians initiated operations in June 1940 from theirEast African colonies ofEthiopia,Italian Somaliland, andEritrea.
As in Egypt, Italian forces (roughly 70,000 Italian soldiers and 180,000 native troops) outnumbered their British opponents.Italian East Africa, however, was isolated and far from the Italian mainland, leaving the forces there cut off from supply and thus severely limited in the operations they could undertake.
Initial Italian attacks in East Africa took two different directions, one intoSudan and the other intoKenya. Then, in August 1940, the Italians advanced intoBritish Somaliland. After suffering and inflicting few casualties, the British and Commonwealth garrison evacuated Somaliland, retreating by sea toAden.
TheItalian invasion of British Somaliland was one of the few successful Italian campaigns of World War II accomplished without German support. In Sudan and Kenya, Italy captured small territories around several border villages, after which the Italian Royal Army in East Africa adopted a defensive posture in preparation for expected British counterattacks.
TheRegia Marina maintained a smallsquadron in the Italian East Africa area. The "Red Sea Flotilla", consisting of sevendestroyers and eightsubmarines, was based at the port ofMassawa in Eritrea. Despite a severe shortage of fuel, the flotilla posed a threat to British convoys traversing theRed Sea. However, Italian attempts to attack British convoys resulted in the loss of four submarines and one destroyer.[77]

On 19 January 1941, the expected British counterattack arrived in the shape of theIndian 4th andIndian 5th Infantry Divisions, which made a thrust from Sudan. A supporting attack was made from Kenya by theSouth African 1st Division, the11th African Division, and the12th African Division. Finally, the British launched an amphibious assault from Aden to re-take British Somaliland.
Fought from February to March, the outcome of theBattle of Keren determined the fate of Italian East Africa. In early April, after Keren fell,Asmara and Massawa followed. The Ethiopian capital ofAddis Ababa also fell in April 1941. The Viceroy of Ethiopia,Amedeo, Duke of Aosta, surrendered at the stronghold of Amba Alagi in May. He received full military honours. The Italians in East Africa made a final stand around the town ofGondar in November 1941.
When the port of Massawa fell to the British, the remaining destroyers were ordered on final missions in the Red Sea, some of them achieving small successes before being scuttled or sunk. At the same time, the last four submarines made an epic voyage around theCape of Good Hope to Bordeaux in France. Some Italians, after their defeat, waged aguerilla war mainly in Eritrea and Ethiopia, that lasted until fall 1943. Notable among them wasAmedeo Guillet.

On 28 October 1940, Italy started theGreco-Italian War by launching an invasion of theKingdom of Greece fromAlbania. In part, the Italians attacked Greece because of the growing influence of Germany in the Balkans. Both Yugoslavia and Greece had governments friendly to Germany. Mussolini launched the invasion of Greece in haste after theKingdom of Romania, a state which he perceived as lying within the Italian sphere of influence, allied itself with Germany. The order to invade Greece was given by Mussolini to Badoglio and Army Chief of StaffMario Roatta on 15 October, with the expectation that the attack would commence within 12 days. Badoglio and Roatta were appalled given that, acting on his orders, they had demobilised 600,000 men three weeks prior.[78] Given the expected requirement of at least 20 divisions to facilitate success, the fact that only eight divisions were currently in Albania, and the inadequacies of Albanian ports and connecting infrastructure, adequate preparation would require at least three months.[78] Nonetheless, D-day was set at dawn on 28 October.
The initial Italian offensive was quickly contained, and the invasion soon ended in an embarrassing stalemate. Taking advantage ofBulgaria's decision to remain neutral, the Greek Commander-in-Chief, Lt GenAlexandros Papagos, was able to establish numerical superiority by mid-November,[nb 3] prior to launching a counter-offensive that drove the Italians back into Albania. In addition, the Greeks were naturally adept at operating in mountainous terrain, while only six of the Italian Army's divisions, theAlpini, were trained and equipped for mountain warfare. Only when the Italians were able to establish numerical parity was the Greek offensive stopped. By then they had been able to penetrate deep into Albania.
An Italian "Spring Offensive" in March 1941, which tried to salvage the situation prior to German intervention, amounted to little in terms of territorial gains. At this point, combat casualties amounted to over 102,000 for the Italians (with 13,700 dead and 3,900 missing) and fifty thousand sick; the Greek suffered over 90,000 combat casualties (including 14,000 killed and 5,000 missing) and an unknown number of sick.[81] While an embarrassment for the Italians, losses on this scale were devastating for the less numerous Greeks; additionally, the Greek Army had bled a significant amount of materiel. They were short on every area of equipment despite heavy infusion of British aid in February and March, with the army as a whole having only 1 month of artillery ammunition left by the start of April and insufficient arms and equipment to mobilize its reserves.[82] Hitler later stated in hindsight that Greece would have been defeated with or without German intervention, and that even at the time he was of the opinion that the Italians alone would have conquered Greece in the forthcoming season.[83]
After British troops arrived in Greece in March 1941, British bombers operating from Greek bases could reach Romanian oil fields, vital to the German war effort. Hitler decided that a British presence in Greece presented a threat to Germany's rear and committed German troops to invade Greece viaYugoslavia (where a coup had deposed the German-friendly government). The Germans invaded on 6 April 1941, smashing through the skeleton garrisons opposing them with little resistance, while the Italians continued a slow advance in Albania and Epirus as the Greeks withdrew, with the country falling to the Axis by the end of the month. The Italian Army was still pinned down in Albania by the Greeks when the Germans began their invasion. Crucially, the bulk of the Greek Army (fifteen divisions out of twenty-one) was left facing the Italians in Albania and Epirus when the Germans intervened. Hitler commented that the Italians "had so weakened [Greece] that its collapse had already become inevitable" and credited them with having "engaged the greater part of the Greek Army."[83]

On 6 April 1941, theWehrmacht invasions of both Yugoslavia (Operation 25) and Greece (Operation Marita) began. Together with the rapid advance of German forces, the Italians attacked Yugoslavia in Dalmatia and finally pushed the Greeks out of Albania. On 17 April, Yugoslavia surrendered to the Germans and the Italians. On 30 April, Greece too surrendered to the Germans and Italians, and was divided into German, Italian, and Bulgarian sectors. The invasions ended with a complete Axis victory in May when Crete fell. On 3 May, during the triumphal parade inAthens to celebrate the Axis victory, Mussolini started to boast of anItalian Mare Nostrum in the Mediterranean.
Some 28 Italian divisions participated in the Balkan invasions. The coast of Yugoslavia was occupied by the Italian Army, while the rest of the country was divided between the Axis forces (a German and Italian creation, theIndependent State of Croatia was born, under the nominal sovereignty ofPrince Aimone, Duke of Aosta, but actually governed by the Croatian leaderAnte Pavelić). The Italians assumed control of most of Greece with their11th Army, while the Bulgarians occupied the northern provinces and the Germans the strategically most important areas. Italian troops wouldoccupy parts of Greece andYugoslavia until the Italian armistice with the Allies in September 1943.
In spring 1941, Italy created aMontenegrin client state and annexed most of theDalmatian coast as theGovernorship of Dalmatia (Governatorato di Dalmazia). A complicated four-way conflict between the puppet Montenegro regime, Montenegrin nationalists, Royalist remnants of the Yugoslav government, and Communist Partisans continued from 1941 to 1945.
In 1942, the Italian military commander in Croatia refused to hand over Jews in his zone to the Nazis.[65]


In 1940, the Italian Royal Navy (Regia Marina) could not match the overall strength of the British Royal Navy in theMediterranean Sea. After some early inconclusive engagements, such as theBattle of Calabria, the Italian Navy mostly declined to engage in a confrontation of capital ships. Since the British Royal Navy had as a principal task the supply and protection ofconvoys supplying Britain's outposts in the Mediterranean, the mere continued existence of the Italian fleet (the so-called "fleet in being" concept) caused problems for Britain, which had to use warships sorely needed elsewhere to protect Mediterranean convoys. On 11 November, Britain used carrier-launchedFairey Swordfish torpedo bombers toattack Taranto. The raid left three Italianbattleships crippled or destroyed for the loss of two British aircraft shot down, and damaged the reputation of the Italians in the eyes of the Germans.[84]
The largest surface fleet battle fought by the Regia Marina in the war was theBattle of Cape Matapan, where it suffered a major defeat against the British Royal Navy and Royal Australian Navy. The British fully utilisedUltra signal intercepts on the movements of the Italian fleet, conducted a successful misinformation campaign on the whereabouts of British ships, and leveraged their strategic edge in having anaircraft carrier in the theatre.[85] A major advantage for the British was the battleshipHMS Valiant had a surface-search radar set, a recent innovation which could detect surface ships up to a range of 16 miles, something the Italian ships had no equivalent of.[86] This allowed the British to not only ambush part of the Italian fleet in the dark, but engage at a very close range where the fire of the British battleships was devastating.[87] The Italians suffered the loss of three heavy cruisers and two destroyers sunk, plus a battleship and one destroyer damaged. British losses were comparatively light, with one aircraft destroyed and four light cruisers damaged. Despite the heavy losses at Cape Matapan, the Regia Marina remained a potent force in Mediterranean. However, the defeat drew the attention of Italian naval commanders to deficiencies compared to the British on use of air power, technology and crew training.[88]
The Italian navy found other ways to attack the British. The most successful involved the use offrogmen andmanned torpedoes to attack ships in harbour. The10th Light Flotilla, also known asDecima Flottiglia MAS or Xª MAS, which carried out these attacks, sank or damaged 28 ships from September 1940 to the end of 1942. These included the battleshipsHMS Queen Elizabeth and HMS Valiant (damaged in the harbour ofAlexandria on 18 December 1941), and 111,527long tons (113,317 t) of merchant shipping. The Xª MAS used a particular kind of torpedo, the SLC (Siluro a Lenta Corsa), whose crew was composed of two frogmen, and motorboats packed with explosives, called MTM (Motoscafo da Turismo Modificato).
On 1942, following the attacks on the two British battleships, theRegia Marina went on the offensive on the Royal Navy, achieving some success at theSecond Battle of Sirte in March, andOperation Vigorous andOperation Harpoon in June; the possibility of Italian dominance over the Mediterranean appeared more achievable. However, Mussolini's brief period of relative success did not last. The oil and supplies brought to Malta in August, at great cost, byOperation Pedestal, as well as the Allied landings in North Africa,Operation Torch, in November 1942, turned the fortunes of war against Italy.Axis forces were ejected from Libya and Tunisia six months after theBattle of El Alamein, while their supply lines were harassed day after day by the growing and overwhelming aerial and naval supremacy of the Allies. By the summer of 1943, the Allies were poised to invade the Italian homeland.

In July 1941, around 62,000 Italian troops of theItalian Expeditionary Corps in Russia (Corpo di Spedizione Italiano in Russia, CSIR) left for theEastern Front to aid in the German invasion of theSoviet Union (Operation Barbarossa). In July 1942, the Italian Royal Army (Regio Esercito) expanded the CSIR to a full army of about 200,000 men named theItalian Army in Russia (Armata Italiana in Russia, ARMIR), also known as the 8th Army.
From August 1942 to February 1943, the 8th Army took part in the decisiveBattle of Stalingrad, where it suffered heavy losses (some 20,000 dead and 64,000 captured) when theSoviets isolated German forces by attacking the over-stretched Hungarian, Romanian, and Italian forces protecting the Germans' flanks. By the summer of 1943, Rome had withdrawn the remnants of the 8th Army to Italy. Many ItalianPOWscaptured in the Soviet Union died in captivity due to harsh conditions in Soviet prison camps.
The outbreak of war saw big demands being made of the Italian population, many of whom were poor to start with, and this placed a strain on the economy, society and adversely impacted the popularity of the war. WhenAllied air raids on Italy began, there were few air raid shelters and according to Behan in the big industrial cities, "people would frequently walk out and sleep in the surrounding countryside".[89] Food was in short supply resulting in rapid price inflation, but wages did not keep pace which spread discontent, as shown by a rise in the number of industrial strikes in early 1943.[90] Many agricultural workers in Sicily struggled to obtain shoes, as the price had risen from around 150 lire a pair before the war to 1,000 lire in 1943.[91] According to Behan, "by early 1943 the anti-fascists had grown in confidence, as they could see more and more people agreeing with them."[92] Replacement troops arriving with Italian military units at the various front lines were drawn from this increasingly discontented and war-weary nation.
The popularity of the war was also hindered by a lack of historic enmity between the Italian people and the main western Allied nations - Britain and the United States. Indeed, Keegan notes that many Italian aristocrats were Anglophiles, while working class Italians held the United States in "high regard".[93] Between 1880 and 1914, four million Italians hademigrated to America, with a further 455,000 following in the 1920s; so many Italians had American relatives.

The High Command were acutely aware of the need to modernize weapons, to close the technology gap with the Allies.[94] Almost 40% of the 1939 budget was allocated for military spending.[95]
Modern equipment was in the pipeline during the 1940-1943 period. Work began converting two commercial ships into aircraft carriers.[nb 4] Three series of modern fighters[nb 5] were in development, as was a medium tank, theCarro Armato P40 - although aspects of the tank, like its riveted armour, meant it was partially obsolete before it had even entered service. However, much of this modern equipment was either still in development at the time of 1943 Armistice, or arrived too late and in insufficient numbers to turn the tide for Italy.
Also, when new Italian weapons were delivered they were often immediately outclassed by the latest upgrade in the equivalent Allied weapon. For instance, in 1941, Italian tank units in North Africa began to receive the newM14/41 tank, which weighed 14.5 tonnes, had front armour of 30mm and a road speed of 21 mph, just as some British units began receiving theCrusader tank, weighing 18.8 tonnes, with front armour of 40mm and a road speed of 26 mph.

On 10 July 1943, a combined force of American and British Commonwealth troopsinvaded Sicily. Although the Axis lost the island after weeks of bitter fighting, they succeeded in ferrying large numbers of German and Italian forces safely off Sicily to the Italian mainland. On 19 July, an Alliedair raid on Rome destroyed both military and collateral civilian structures. With these two events, popular support for the war diminished in Italy.[97]
On 25 July, theGrand Council of Fascismvoted to limit the power of Italian dictator Benito Mussolini and handed control of the Italian armed forces over to KingVictor Emmanuel III. The next day, Mussolini met with the King, was dismissed as prime minister, and then imprisoned. A new Italian government, led by General Pietro Badoglio and Victor Emmanuel III, took over in Italy.
Although they publicly declared that they would keep fighting alongside the Germans, the new Italian government began secret negotiations with the Allies to come over to the Allied side.[98] Tensions between the Axis and the Italian military were rising following the failure to defend Sicily, withNew York Times correspondent Milton Bracker noting that "Italian hatred of the Germans unquestionably grew as the fighting spirit waned, and episodes between German and Italian soldiers and civilians before and after the armistice have shown pretty clearly a complete and incontrovertible end of all sympathy between the former Axis partners."[99]
On 3 September, a secretarmistice was signed with the Allies at Fairfield Camp in Sicily. The armistice was publicly announced on 8 September. By then, the Allies were on the Italian mainland.
On 3 September, British troops crossed the short distance from Sicily to the 'toe' of Italy inOperation Baytown. Two more Allied landings took place on 9 September atSalerno (Operation Avalanche) and atTaranto (Operation Slapstick). The Italian surrender meant that the Allied landings at Taranto took place unopposed, with the troops simply disembarking from warships at the docks rather than assaulting the coastline.

Because of the time it took for the new Italian government to negotiate the armistice, the Germans had time to reinforce their presence in Italy and prepare for their defection. In the first weeks of August, they increased the number of divisions in Italy from two to seven and took control of vital infrastructure.[100] Once the signing of the armistice was announced on 8 September, German troops quickly disarmed the Italian forces and took over critical defensive positions inOperation Achse. This included Italian-occupied southeastern France and the Italian-controlled areas in the Balkans. Only inSardinia,Corsica, and in part ofApulia andCalabria were Italian troops able to hold their positions until the arrival of Allied forces. In the area ofRome, only one infantry division—theGranatieri di Sardegna—and some small armoured units fought with commitment, but by 11 September they were overwhelmed by superior German forces.
King Victor Emmanuel III and his family, with Marshal Badoglio, General Mario Roatta, and others, abandoned Rome on 9 September. General Caroni, who was tasked with defending Rome, was given duplicitous orders to have his troops abandon Rome (something he did not want to do), and essentially to provide rear guard protection to the King and his entourage so they could flee to the Abruzzi hills, and later out to sea. They later landed atBrindisi. Most importantly, Badoglio never gave the "OP 44" order for the Italian people to rise up against the Germans until he knew it was too late to do any good; that is, he belatedly issued the order on 11 September. However, from the day of the announcement of the Armistice, when Italian citizens, military personnel and military units decided to rise up and resist on their own, they were sometimes quite effective against the Germans.[101]
As part of the terms of the armistice, the Italian fleet was to sail to Malta for internment; as it did so, it came under air attack by German bombers, and on 9 September two GermanFritz X guided bombs sank the Italian battleshipRoma off the coast ofSardinia.[102] ASupermarina (Italian Naval Command) broadcast led the Italians to initially believe this attack was carried out by the British.[103]

On the Greek island ofCephallonia, GeneralAntonio Gandin, commander of the 12,000-strong ItalianAcqui Division, decided to resist the German attempt to forcibly disarm his force. The battle raged from 13 to 22 September, when the Italians capitulated having suffered some 1,300 casualties. Following the surrender,the Germans proceeded to massacre thousands of the Italian prisoners.
Italian troops captured by the Germans were given a choice to keep fighting with the Germans. About 94,000 Italians accepted and the remaining 710,000 were designatedItalian military internees and were transported as forced labour to Germany. Some Italian troops that evaded German capture in the Balkans joined theYugoslav (about 40,000 soldiers) andGreek Resistance (about 20,000).[104] The same happened in Albania.[105]
After the German invasion,deportations of Italian Jews to Nazideath camps began. However, by the time the German advance reached the Campagna concentration camp, all the inmates had already fled to the mountains with the help of the local inhabitants. Rev.Aldo Brunacci ofAssisi, under the direction of his bishop,Giuseppe Nicolini, saved all the Jews who sought refuge in Assisi. In October 1943 Nazis raided the Jewish ghetto in Rome. In November 1943 Jews ofGenoa andFlorence were deported toAuschwitz. It is estimated that 7,500 Italian Jews became victims of theHolocaust.[65]
After Mussolini had been stripped of power, he was imprisoned atGran Sasso in theApennine mountains. On 12 September 1943 he was rescued by the Germans inOperation Eiche ("Oak"). The Germans re-located him to northern Italy where he set up a new Fascist state, theItalian Social Republic (Repubblica Sociale Italiana or RSI). Many Italian personalities joined the RSI, like GeneralRodolfo Graziani. This led, within the context of the Italian campaign, to a civil war between the forces loyal to the Kingdom of Italy, now fighting on the Allied side, and the Fascists who collaborated with the Germans.
On 13 October 1943, the Kingdom of Italy, which was now based outside of Mussolini's control, formally became a co-belligerent of the Allies by declaring war on Nazi Germany.[99] With Allied assistance some Italian troops in the south were re-organized into what were known as "co-belligerent" or "royalist" forces. In time, there was a co-belligerent army (Italian Co-Belligerent Army), navy (Italian Co-Belligerent Navy), and air force (Italian Co-Belligerent Air Force). These Italian forces fought alongside the Allies against the Germans for the rest of the war.

The Allied armies continued to advance through Italy despite increasing opposition from the Germans. The Allies soon controlled most of southern Italy, andNaples rose against and ejected the occupying German forces. The loyalist Italian government (sometimes referred to as the "Kingdom of the South") declared war on Germany on 13 October, aligning Italy within the Western Allies as aco-belligerent. Other Italian troops, loyal to Mussolini and his RSI, continued to fight alongside the Germans (among them theEsercito Nazionale Repubblicano, theNational Republican Army). From this point on, a largeItalian resistance movement located in northern Italy fought aguerilla war against the German and RSI forces.


Winston Churchill had long regarded southern Europe as the military weak spot of the continent, and in particular called Italy the "soft underbelly" of the Axis.[106] In ironic riposte, the episode of the epic World War II documentary seriesThe World at War that covered the Italian campaign was titled 'Tough Old Gut'. Allied progress on the Italian mainland was slow and difficult, hindered by mountainous terrain, many rivers and the narrowness of the peninsula, which meant the battle favoured the defender.[107] However, the campaign played an important role in the wider Allied prosecution of the European war, as by the time the Allies reached theGothic Line twenty six Axis divisions were tied-up fighting in Italy that otherwise could have been committed to other fronts.[108] The final and total Allied victory over the Axis in Italy was secured by thespring offensive of 1945, after Allied troops had breached the Gothic Line. Mussolini wascaptured and killed on 28 April 1945 by the Italian resistance while attempting to flee. The surrender of German and RSI forces in Italy occurred on 2 May, shortly before Germany finally surrendered ending World War II in Europe on 8 May.
Japan reacted with shock and outrage to the news of the surrender of Italy to the Allied forces in September 1943. Italian citizens residing in Japan and in Manchukuo were swiftly rounded up and summarily asked whether they were loyal to the King, who dishonoured their country by surrendering to the enemy, or with the Duce and the newly createdItalian Social Republic, which vowed to continue fighting alongside the Germans. Those who sided with the King were interned in concentration camps and detained in dismal conditions until the end of the war, while those who opted for the Fascist dictator were allowed to go on with their lives, although under strict surveillance by theKempeitai.
TheItalian concession of Tientsin was occupied by Japanese troops with no resistance from its garrison. The Social Republic of Italy later formally gave it to the Japanese puppetReorganized National Government of the Republic of China.
The news of Italy's armistice did not reach the crew members of the three Italian submarinesGiuliani,Cappellini andTorelli travelling toSingapore, then occupied by Japan, to take a load of rubber, tin, and strategic materials bound for Italy and Germany's war industry. All the officers and sailors on board were arrested by the Japanese army, and after a few weeks of detention the vast majority of them chose to side with Japan and Germany. TheKriegsmarine assigned new officers to the three units, who were renamed asU-boatU.IT.23,U.IT.24, andU.IT.25, taking part in German war operations in the Pacific until theGiuliani was sunk by theBritish submarine HMSTally-ho in February 1944 and the other two vessels were taken over by theJapanese Imperial Navy upon Germany's surrender in 1945.
Alberto Tarchiani, an anti-fascist journalist and activist, was appointed as Ambassador to Washington by the cabinet of Badoglio, which acted as provisional head of the Italian government pending the occupation of the country by the Allied forces. On his suggestion, Italy issued a formal declaration of war on Japan on 14 July 1945.[109]
As early as of May 1945, theItalian destroyerCarabiniere had been prepared and refitted with a new radar and camouflage scheme to operate in the Indian and Pacific Ocean against the Japanese Empire, in collaboration with the Allies. Departing under the command of Captain Fabio Tani, after a troublesome voyage the Italian crew reached their new base inTrincomalee. By August 1945, the Carabiniere had undertaken 38 missions of anti-aircraft and anti-submarine escort to British warships and SAR operations. They thoroughly impressedAdmiral Arthur Power of theEastern Fleet during combat and in defending the fleet against kamikaze attacks, and he offered captain Tani a golden watch with 38 rubies, one for each mission, as a prize for their valour. Captain Tani kindly declined and requested that an Italian POW for each ruby be released instead, which was granted by the Admiral.[110]
A further purpose of the Italian declaration of war on Japan was to persuade the Allies that the new government of Italy deserved to be invited to theSan Francisco Peace Conference, as a reward for itsco-belligerence. However, British Prime Minister Churchill andJohn Foster Dulles were resolutely against the idea, and so Italy's new government was left out of the Conference.
Italy and Japan negotiated the resumption of their respective diplomatic ties after 1951, and later signed several bilateral agreements and treaties.[111]

Nearly four million Italians served in the Italian Army during the Second World War and nearly half a million Italians (including civilians) lost their lives between June 1940 and May 1945.

The official Italian government accounting of World War II 1940–45 losses listed the following data:
Prisoner-of-war losses are included with military losses mentioned above.
The members in the Roll of Honor of the World War II (sic) amounted to a total of 319,207 deaths:[113]
Civilian losses totalled 153,147 (123,119 post armistice) including 61,432 (42,613 post armistice) in air attacks.[114] A brief summary of data from this report can be found online.[115]
In addition, deaths of African soldiers conscripted by Italy were estimated by the Italian military to be 10,000 in the 1940–41East African Campaign.[116]
Civilian losses as a result of the fighting inItalian Libya were estimated by an independent Russian journalist to be 10,000.[117]
Included in total are 64,000 victims of Nazi reprisals and genocide, including 30,000 POWs and 8,500 Jews[118] Russian sources estimated the deaths of 28,000 of the 49,000Italian prisoners of war in the Soviet Union (1942–1954).[119]
The genocide ofRoma people killed 1,000 persons.[120] JewishHolocaust victims totalled 8,562 (including Libya).[121]
After the armistice with the Allies, some 650,000 members of the Italian armed forces who refused to side with the occupying Germans were interned in concentration and labour camps. Of these, around 50,000 died while imprisoned or in transit.[122] A further 29,000 died in armed struggles against the Germans while resisting capture immediately following the armistice.[122]
The1947 Treaty of Peace with Italy spelled the end of theItalian colonial empire, along with other border revisions. The1947 Paris Peace Treaties compelled Italy to pay $360,000,000 (US dollars at 1938 prices) in war reparations: $125,000,000 toYugoslavia, $105,000,000 to Greece, $100,000,000 to the Soviet Union, $25,000,000 toEthiopia and $5,000,000 to Albania. Italy also agreed to pay £1,765,000 to Greek nationals whose property in Italian territory had been destroyed or seized during the war.[123] In the1946 Italian constitutional referendum, theItalian monarchy was abolished, having been associated with the deprivations of the war and Fascist rule. Unlike in Germany and Japan, nowar crimes tribunals were held for Italian military and political leaders, though the Italian resistancesummarily executed some of them, including Mussolini, at the end of the war.
British wartime propaganda trumpeted the destruction of the Italian 10th Army by a significantly smaller British force duringOperation Compass,[124] which came at a time British morale needed a boost during a bleak period of the war. However, this left a lasting impression that shaped public attitudes long after the war ended, promoting a popular culture stereotype of a mythical Italian soldier who quickly surrendered.[125] Many histories of the North African campaign written in the immediate decades after the Second World War often focussed on the exploits ofErwin Rommel, and consequently downplayed the Italian role; with some historians relying too heavily on Allied and German primary sources, in part hampered by few Italian sources having been translated into English.[126][127][128]
James Sadkovich, Peter Haining,Vincent O'Hara, Ian Walker and others have attempted to reassess the performance of Italian forces. Some actions where Italian troops performed strongly have been overlooked by historians as they were sub-battles of a much larger battle whose outcome drew most of the attention - an example is theaction of Bir El Gubi in December 1941, where a battalion group ofGiovani Fascisti held up the11th Indian Infantry Brigade and destroyed ten tanks of the 22nd Armoured Brigade, which tends to be viewed as part of the major battle,Operation Crusader.
During theTunisian campaign, where Italian units were involved in most encounters, such as the battles of Kasserine Pass, Mareth, Akarit, and Enfidaville, it was observed byGeneral Alexander, "...the Italians fought particularly well, outdoing the Germans in line with them".[129] Rommel also conceded praise on several occasions.[nb 6] Gerhard L.Weinberg, in his 2011 George C. Marshall Lecture "Military History – Some Myths of World War II" (2011), complained that "there is far too much denigration of the performance of Italy's forces during the conflict."[134]

The British historian, Ian Walker, paid tribute to the personal courage of Italian tank crews when he wrote:
....it is perhaps simplest to ask who is the most courageous in the following situations: the Italiancarristi, who goes into battle in an obsolete M14 tank against superior enemy armour and anti-tank guns, knowing they can easily penetrate his flimsy protection at a range where his own small gun will have little effect;[nb 7] the German panzer soldier or British tanker who goes into battle in a Panzer IV Special or Sherman respectively against equivalent enemy opposition knowing that he can at least trade blows with them on equal terms; the British tanker who goes into battle in a Sherman against inferior Italian armour and anti-tank guns, knowing confidently that he can destroy them at ranges where they cannot touch him. It would seem clear that, in terms of their mottoFerrea Mole, Ferreo Cuore, the Italiancarristi really had "iron hearts", even though as the war went on their "iron hulls" increasingly let them down.
— Walker[137]
Accusations that Italians were reluctant to fight are also disproved by the activities of theItalian resistance movement, which fought against the Nazi occupation of central and northern Italy between 1943 and 1945, and battled the forces of the German puppet Italian Social Republic. In May 1944, General Alexander, commander of Allied15th Army Group, estimated six Axis divisions in Italy were tied up fighting partisan groups.[138] It has been estimated that by spring 1945, around 300,000 people were fighting in the partisan forces.[139] There was a major uprising against the Germans inNaples in the days running up to Allied forces reaching the city. Several major Italian cities were liberated by Italian resistance fighters before Allied troops arrived, including Genoa, Milan and Turin.[140]
Undoubtedly, there were several occasions where the timely arrival of German military assistance helped avert disaster for the Italians, such as the dispatch of theAfrika Korps to Libya in 1941, and theGerman invasion of Greece, also in 1941. Italy sent aforce to fight alongside the Germans on the Eastern Front between July 1941 and March 1943.
However, the alliance between Italy and Nazi Germany never saw the same level of co-operation, trust and mutual respect that occurred between the USA and Britain in World War Two. James Holland wrote of the "naked contempt with which Nazi Germany regarded its allies".[141] While the alliance between Germany and Italy had started well, with good personal relations between Hitler and Mussolini, by 1939 it was already beginning to sour with the signing of theMolotov–Ribbentrop Pact without consulting Italy and Germany starting a major European war when Italy was far from militarily ready to fight.[142] Illustrating the level of underlying mistrust, in 1940 Rome assigned more money to strengthening theAlpine fortifications facing the Third Reich than to those on the border with France, and work on these forts continued until October 1942.[143] This suggests that despite the Axis alliance with Hitler, Mussolini still viewed a German attack at a later date as a real risk.
After the Italian invasion of Greece stalled in late 1940, and in the aftermath of the British air attack on the navy base at Taranto, the Italian military attaché in Berlin, GeneralLuigi Efisio Marras, was no longer given the special treatment afforded to the representative of a ally.[144] During a joint visit to troops on the Eastern Front in 1941 by Hitler and Mussolini, a German official was overheard referring to Mussolini as theGauleiter of Italy.[145] According to Goeschel, the Germans viewed the Italian soldiers sent to the Eastern Front as "auxiliary troops".[146]
A large share of the responsibility for Fascist Italy's poor military performance in World War II rests with Mussolini. The Duce plunged Italy into the war for opportunistic reasons in June 1940, despite having been repeatedly warned the armed forces were not ready - Mussolini toldGeneral Carlo Rossi in May 1940: "If I had to wait for the army to be ready, I would have to wait years to enter the war, but I have to enter it now. We shall do what we can."[147] GeneralGiuseppe Castellano, who signed the armistice with the Allies in 1943, wrote of Mussolini: "the errors were essentially of a political nature and many times the military were thrust into more dangerous adventures through the incompetence and intemperance of the man who ran the government."[148] Gooch concluded: "Mussolini had little if any comprehension of military strategy and none at all of grand strategy."[149]
Historians also attribute Italian military shortcomings to failings in strategy and poor equipment. Italian equipment was generally substandard. Many tanks and aircraft were "a whole generation outdated" by those used by the British in the early war, with Italian weapons then becoming hopelessly obsolete with the arrival of US equipment, such as theM4 Sherman, and as the British upgraded their weapon designs.[150] Crucially, Italian forces lacked suitable quantities of equipment of all kinds,[151] and Italy's relative backwardness in industrialisation hampered ramping up production in wartime, with weapons (according to Keegan) "produced by artisan methods which could not match the output of British - and eventually American - factories working to volume demands".[152] This was compounded by Mussolini's assigning unqualified political favourites to key positions. Mussolini also dramatically overestimated the ability of the Italian military at times, sending them into situations where failure was likely, such as the invasion of Greece.[153]
Historians have long debated why Italy's military and Fascist regime proved ineffective at an activity — war — that was central to their identity. MacGregor Knox explains that this "was first and foremost a failure of Italy's military culture and military institutions."[154] Donald Detwiler writes that "Italy's entrance into the war showed very early that her military strength was only a hollow shell. Italy's military failures against France, Greece, Yugoslavia, and in the African Theatres of war shook Italy's new prestige mightily."[155] James Sadkovich surmises that Italian failures were caused by inferior equipment,overextension, and inter-service rivalries. Its forces had "more than their share of handicaps."[156]
