TheItalian Co-belligerent Army (Italian:Esercito Cobelligerante Italiano), orArmy of the South (Esercito del Sud), were names applied to various units of the now formerRoyal Italian Army during the period when they fought alongside theAllies during theItalian Campaign andcivil war ofWorld War II from October 1943 onwards. During the same period, thepro-alliedItalian Royal Navy andItalian Royal Air Force were known as theItalian Co-belligerent Navy andItalian Co-belligerent Air Force respectively. From September 1943, pro-Axis Italian forces became theNational Republican Army of the newly formedItalian Social Republic.
The Italian Co-belligerent Army was the result of theAllied armistice with Italy on 8 September 1943;King Victor Emmanuel III dismissedBenito Mussolini as Prime Minister in July 1943 following the Allied invasion of Southern Italy, and nominatedMarshal of Italy (Maresciallo d'Italia)Pietro Badoglio instead, who later aligned Italy with the Allies to fight the Social Republic's forces and its German allies inNorthern Italy.
The Italian Co-belligerent Army fielded between 266,000 and 326,000 troops in the Italian Campaign, of whom 20,000 (later augmented to 50,000, though some sources place this number as high as 99,000) were combat troops and between 150,000 and 190,000 were auxiliary and support troops, along with 66,000 personnel involved with traffic control and infrastructure defence.[1] On the whole, the Italian Co-Belligerent Army made up 1/8 of the fighting force and 1/4 of the entire force of15th Army Group of theAllied Forces.
The first formation of the Co-belligerent Army was theI Motorized Grouping (Italian:I Raggruppamento Motorizzato) created on 27 November 1943 inSan Pietro Vernotico nearBrindisi. The units for the I Motorized Grouping were drawn from the58th Infantry Division "Legnano" and18th Infantry Division "Messina".[2] Some of the soldiers who joined the unit had managed to evade capture andinternment by German forces.[3] The unit was composed of 295 officers and 5,387 men and was created to participate alongside theAllies against Germany and the Italian Social Republic in theItalian campaign. The unit was commanded by GeneralVincenzo Dapino, who led it during its first engagement in theBattle of San Pietro Infine in December of the same year. This action did much to remove the Allies' distrust of Italian soldiers fighting on their side.[4] The unit suffered heavy casualties and was judged to have performed satisfactorily.[5]
Following the service with theAmerican Fifth Army and reorganization, command of the I Motorized Grouping was given to GeneralUmberto Utili and the unit was transferred to thePolish II Corps on the extreme left of theBritish Eighth Army.[4] In early 1944 the unit was reorganised and expanded into the Italian Liberation Corps.[6]
On 18 April 1944, the I Motorized Grouping (now 16,000 men strong) assumed the name Italian Liberation Corps (Italian:Corpo Italiano di Liberazione, or CIL) and was divided into two brigades.[7][4] The CIL was augmented with the 6,000 men strong184th Infantry Division "Nembo". The CIL's commander was GeneralUmberto Utili. In early 1944, a 5,000-man force of Italians fought on theGustav Line aroundMonte Cassino and acquitted itself well. The Italians once again suffered heavy casualties.[5]
After theBattle of Filottrano [it] in July 1944 the Italian government proposed to increase the number of Italian troops fighting on the Allied side. The proposal was accepted and in September 1944 the CIL was taken out of the line and sent to the rear to be equipped with British material, includingBritish Battledress uniforms andhelmets. On 24 September 1944, the CIL was disbanded and its personnel and units used to form the first combat groups: "Legnano" and "Folgore". Soon four more combat groups were formed: "Cremona", "Friuli", "Mantova", and "Piceno". These groups were equal in size to weak divisions. The established strength for each was 432 officers, 8,578 other ranks, 116 field guns, 170 mortars, 502 light machine guns, and 1,277 motor vehicles. The Combat Groups were given the names of old Royal Army divisions and followed the numbering system of older regiments to some extent.[5] These groups were attached to various American and British formations on theGothic Line. The following is the "order of battle" of the Italian Co-belligerent Army as of April 1945.[8]
The Chief of Staff of the Armed Forces High Command was MarshalGiovanni Messe, while the Chief of Staff of the Army was Lieutenant GeneralPaolo Berardi.
Each infantry regiment fielded three infantry battalions, a mortar company armed with BritishML 3 inch mortars and an anti-tank company armed with BritishQF 6 pounder guns. The artillery regiments consisted of four artillery groups with BritishQF 25 pounder guns, one anti-tank group with BritishQF 17 pounder guns and one anti-air group armed with British versions of theBofors 40mm gun.

In addition to the Combat Groups the Italian Co-belligerent Army included eight Auxiliary Divisions (Italian:Divisioni Ausiliarie) for labour, support and second-line duties. At its peak the division fielded about 150,000-190,000. These auxiliary units were the following:
On the whole the Italian Co-Belligerent Army made up 1/8 of the fighting force and 1/4 of the entire force of15th Army Group of theAllied Forces.[9]
Not directly dependent from the Allied Headquarters in Italy the Co-Belligerent Army also deployed three Internal Security Divisions (Divisioni di Sicurezza Interna) for internal security duties:
In 1946, theKingdom of Italy became theItalian Republic. In a similar manner, what had been the royalist Co-Belligerent Army simply became theItalian Army (Esercito Italiano).
The Italian Liberation Corps suffered 1,868 killed and 5,187 wounded during the Italian campaign;[10] the Italian Auxiliary Divisions lost 744 men killed, 2,202 wounded and 109 missing.[11] Some sources estimate the overall number of members of the Italian regular forces killed on the Allied side as 5,927.[12]
