SMSKaiser Franz Joseph I[e] (sometimes called theKaiser Franz Josef I[1]) was aprotected cruiser built for theAustro-Hungarian Navy. Named for the Austrian emperor and Hungarian kingFranz Joseph I,Kaiser Franz Joseph I was thelead ship of hernamesake class. Constructed byStabilimento Tecnico Triestino inTrieste, she waslaid down in January 1888 andlaunched in May 1889.Kaiser Franz Joseph I wascommissioned into the Navy in June 1890. As the first protected cruiser constructed by the Austro-Hungarian Navy, she was intended to serve as Austria-Hungary's response to the Italian cruisersGiovanni Bausan andEtna. Her design was heavily influenced by theJeune École (Young School), anaval strategy which had gained prominence in the 1880s as a means to combat a larger and more heavily armored navy ofbattleships through the use of torpedo flotillas.
Changes in technology and strategic thinking through the adoption ofAlfred Thayer Mahan's "decisive battle" doctrine which stressed the construction of powerful battleships as the primarycapital ship of navies around the world rendered the design of theKaiser Franz Joseph I obsolete shortly after her commissioning. Nevertheless, she and her sister shipKaiserin Elisabeth remained an important component of Austro-Hungarian naval policy, which continued to emphasize coastal defense and overseas missions toshow the flag around the world. During the course of her career,Kaiser Franz Joseph I participated in several overseas voyages, including several tours of duty to defend Austro-Hungarian interests in China following theBoxer Rebellion.
At the outbreak of World War I in 1914,Kaiser Franz Joseph I was assigned to the Fifth Battle Division and stationed at the Austro-Hungarian naval base atCattaro. Due to her age and obsolete design,Kaiser Franz Joseph I saw little action during most of the conflict, though she did participate in shelling Franco-Montenegrin artillery batteries located on the slopes ofMount Lovćen in late 1914, which overshadowed theBocche di Cattaro. In January 1916, when the Austria-Hungary began aninvasion of Montenegro,Kaiser Franz Joseph I assisted in again silencing Montenegrin batteries on Mount Lovćen in support of theAustro-Hungarian Army, which seized the mountain and subsequently captured the Montenegrin capital ofCetinje, knocking the country out of the war.
In 1917,Kaiser Franz Joseph I was decommissioned, disarmed, and converted into a headquarters ship for the Austro-Hungarian base at Cattaro. She remained in this capacity through the rest of the war. When Austria-Hungary was facing defeat in October 1918, the Austrian government transferred its navy to the newly formedState of Slovenes, Croats and Serbs in order to avoid having to hand the ship over to theAllies. Following theArmistice of Villa Giusti in November 1918, an Allied fleet sailed into Cattaro and seized the former Austro-Hungarian ships stationed in the Bocche, includingKaiser Franz Joseph I. She was ceded to France as awar reparation after the war, but sank during a gale offKumbor in October 1919. Her wreck was twice salvaged in 1922 and 1967. Two of her cannons are in Cetinje, Montenegro.
On 13 November 1883, Emperor Franz Joseph I promotedMaximilian Daublebsky von Sterneck to the office of vice admiral, and named himMarinekommandant of the Austro-Hungarian Navy as well as Chief of the Naval Section of the War Ministry (German:Chef der Marinesektion).[2] Sterneck's presence at theBattle of Lissa, and his past ties to AdmiralWilhelm von Tegetthoff, led to his promotion being widely supported within the Navy. After spending his first years asMarinekommandant reforming the administrative bureaucracy of the Navy, Sterneck began to pursue a new program of warship construction in the late 1880s and early 1890s.[3]
In the 1880s, the naval philosophy ofJeune École began to gain prominence among smaller navies throughout Europe, particularly within theFrench Navy, where it was first developed by naval theorists wishing to counter the strength of the BritishRoyal Navy.Jeune École advocated the use of a powerful armed fleet primarily made up of cruisers, destroyers, and torpedo boats to combat a larger fleet made up of ironclads and battleships, as well as disrupt the enemy's global trade.[4]Jeune École was quickly adopted as the main naval strategy for Austria-Hungary under the leadership of Sterneck.[5] His strong support forJeune École was rooted in a belief that the strategy appeared to fit existing Austro-Hungarian naval policy, which stressed coastal defense and limited power projection beyond the Adriatic Sea. Tests conducted by the Austro-Hungarian Navy during the early and mid 1880s led Sterneck to believe that torpedo boat attacks against a fleet of battleships, a central component ofJeune École, would have to be supported by larger ships such as cruisers. As Austria-Hungary lacked the ability to disrupt global trade due to its location in theAdriatic Sea, and the two potential enemies the Navy could find itself at war with–Italy and Russia–lacked suitable targets for commerce raiding or overseas colonies, the cruisers which would be designed under the principles ofJeune École would instead focus on coastal defense and leading torpedo boat flotillas as opposed to commerce raiding. These tests, as well as the adoption ofJeune École as the principal naval strategy of the Austro-Hungarian Navy, led to the development ofKaiser Franz Joseph I.[6]
Under the Navy's 1881 plan which was passed by his predecessor,Friedrich von Pöck, Sterneck proposed the construction of a class of cruisers to the Austrian and Hungarian Delegations for Common Affairs as "replacements" for the Austro-Hungarian ironcladsLissa andKaiser.[7][f]Kaiser had not seen active service since 1875 and Pöck had intended to have her replaced prior to his resignation in 1883.Lissa had been reassigned to the II Reserve by 1888.[8] The Delegations strongly supported the proposal for the cruisers, in large part due to their relatively low price compared to other capital ships of the era.[9] Two cruisers built to the specifications ofKaiser Franz Joseph I would cost 5,360,000florins, while the ironclad warshipKronprinz Erzherzog Rudolf, laid down in 1884, had cost ƒ5,440,000 to construct.[7] The Delegations thus allocated funding to construct twoKaiser Franz Joseph I-class ships—"Ram Cruiser A" and "Ram Cruiser B" (German:"Rammkreuzer A" and"Rammkreuzer B")—under the 1888 and 1889 budgets. "Ram Cruiser A" would eventually becomeKaiser Franz Joseph I.[10][g] This means thatKaiser Franz Joseph I's construction costs were later recorded as being 5,146,884 Krone.[11]
Authorized near the start of Austria-Hungary's second naval arms race against Italy, Sterneck had intendedKaiser Franz Joseph I and her sister ship to serve as Austria-Hungary's response to the Italian cruisersGiovanni Bausan andEtna.[12] Intended as a counter to the growing strength of the ItalianRegia Marina,Kaiser Franz Joseph I was designed to lead a torpedo flotilla into battle against a larger fleet of battleships.[13] While Italy and Austria-Hungary had become allies under the 1882Triple Alliance, Italy's Regia Marina remained the most-important naval power in the region which Austria-Hungary measured itself against, often unfavorably. Despite the Austrian victory at sea after theBattle of Lissa during theThird War of Italian Independence, Italy still possessed a larger navy than Austria-Hungary in the years following the war. The disparity between the Austro-Hungarian and Italian navies had existed ever since theAustro-Italian ironclad arms race of the 1860s. While Austria-Hungary had shrunk the disparity in naval strength throughout the 1870s, Italy boasted the third-largest fleet in the world by the late 1880s, behind the French Navy and the British Royal Navy.[14]
Sterneck hailed theKaiser Franz Joseph I and her sister ship as the "battleships of the future", and it was envisioned that she would lead a torpedo division made up of one light cruiser, one destroyer, and six torpedo boats. The displacement and speed ofKaiser Franz Joseph I also illustrated Austria-Hungary's application ofJeune École, while her prominent ram bow reflected the legacy of the Battle of Lissa, which saw a much smaller Austrian fleet defeat the Italian Regia Marina using ramming tactics. Sterneck envisioned a hypothetical engagement with the Italian Regia Marina devolving into a chaotic melee similar to the Battle of Lissa, withKaiser Franz Joseph I and her sister ship leading torpedo divisions against their opponents. Her bow ram would maximize damage in an engagement of this sort and allow her to sink enemy vessels in a similar fashion to Tegetthoff at Lissa. Her two large guns were also chosen in order to give credence to Sterneck's plan forKaiser Franz Joseph I to help replace heavily armored ironclads and battleships as the primary capital ship of the Austro-Hungarian Navy.[15]
Designed by Chief EngineerFranz Freiherr Jüptner,[16]Kaiser Franz Joseph I had anoverall length of 103.7–103.9 meters (340 ft 3 in – 340 ft 11 in) and alength between perpendiculars of 97.9 meters (321 ft 2 in). She had abeam of 14.75–14.8 meters (48 ft 5 in – 48 ft 7 in),[a] and a meandraft of 5.7 meters (18 ft 8 in) atdeep load. She was designed to displace 3,967 metric tons (3,904 long tons; 4,373 short tons) at normal load, but at full combat load she displaced 4,494 metric tons (4,423 long tons; 4,954 short tons).[17][18] She was manned by a crew of 367 to 444 officers and men.[17][19][18][c]
Her propulsion systems consisted of two shafts which operated twoscrew propellers measuring 4.35 meters (14 ft 3 in) in diameter.[19] These propellers were powered by two sets of horizontaltriple expansion engines, designed to provide 8,000–8,450shaft horsepower (5,970–6,300 kW).[b] These engines were powered by four cylindrical double-ended boilers, which gaveKaiser Franz Joseph I a top speed of 19.65 knots (36.39 km/h; 22.61 mph) while conductingsea trials. In order to power her boilers,Kaiser Franz Joseph I carried 670 metric tons (660 long tons; 740 short tons) of coal. This gave her a range of approximately 3,200nautical miles (5,900 km; 3,700 mi) at 10 knots (19 km/h; 12 mph).[17][19][18]
Kaiser Franz Joseph I had an armament system which was based heavily off of the design of "Elswick cruisers" such as the Chilean cruiserEsmeralda.[13] She was armed with amain battery of two24 cm (9.4 in) K L/35Krupp guns, mounted in turrets fore and aft. Hersecondary armament consisted of six15 cm (5.9 in) SK L/35 guns, mounted incasematesamidships with three on either side. She also possessed 1647 mm (1.9 in) SFK L/44 guns, and four 40–45 cm (16–18 in)torpedo tubes with two located at the bow and stern, and two located amidships.[17][d] These heavy guns were intended to help the cruiser open fire on heavier battleships from a distance while supporting torpedo boat attacks on an enemy warship or fleet.[15][13] In 1905,Kaiser Franz Joseph I underwent a refit for modernization. During this refit, her main battery was replaced by two15 cm (5.9 in) SK L/40Škoda guns.[20]
The mountings her main guns were located on consisted of a rotating platform and a domed gun turret. These turrets were operated by a series of steam pumps below the deck of both ships. While each turret had its own steam pump, pipes ran the length of the ship to connect each steam pump and their accompanying turret together in order to provide a backup system should one of the steam pumps be disabled in combat. The maximum elevation of the two main guns, as well as their loading angle, was 13.5°. When at this angle, the range of the main guns' 215 kilograms (474 lb) shells was 10,000 meters (11,000 yd). The maximum elevation of the ships' secondary armament was 16°, and their 21 kilograms (46 lb) shells had the same range as the main battery.[21]
Kaiser Franz Joseph I was protected at the waterline with anarmored belt measuring 57 mm (2.2 in) thick. Theturrets had 90 mm (3.5 in) thick armor, while the thickness of the deck armor was 38 mm (1.5 in). Herconning tower was protected by 50–90 mm (2.0–3.5 in) armor.[22][18] The machinery forKaiser Franz Joseph I was assembled byStabilimento Tecnico Triestino, and she was constructed with a double-bottom hull and designed with over 100 watertight compartments. The steam-powered pumps used to control flooding aboardKaiser Franz Joseph I could discharge 1,200 metric tons (1,200 long tons; 1,300 short tons) of water per hour.[19]
The defensive systemsKaiser Franz Joseph I- also consisted ofcoal bunkers located abreast the boiler rooms, and a horizontalcofferdam located at her waterline, which was filled withcellulose fiber. The fiber was intended to seal up any holes in the ship from artillery rounds by swelling up upon contact with seawater, while the impacting shell itself would be slowed down by the surrounding coal, which would also serve to contain any explosions.[13]
Kaiser Franz Joseph I was laid down by Stabilimento Tecnico Triestino at Trieste under the designation "Ram Cruiser A" on 3 January 1888.[13] "Ram Cruiser A" was formally namedKaiser Franz Joseph I when she was launched at Trieste on 18 May 1889.[11] After conducting sea trials,Kaiser Franz Joseph I was commissioned into the Austro-Hungarian Navy on 2 July 1890.[18][23]
Changes in both technology as well as naval doctrine renderedKaiser Franz Joseph I obsolete shortly after her commissioning. Indeed, the rapid decline ofJeune Ecole during the 1890s and 1900s soon rendered the concept of "ram cruisers" obsolete as a whole. The thin armor, slow speed, and slow-firing guns present on ships such asKaiser Franz Joseph I led to Sterneck's "battleships of the future" being labeled as "tin cans" and "Sterneck's sardine–boxes" by Austro-Hungarian sailors and naval officers.[7][24][10][25] The poor receptionKaiser Franz Joseph I and her sister ship received due to these changes in technological development and strategic thinking thus contributed to the Austro-Hungarian Navy's decision to transition away from cruisers to battleships as the primary capital ship of the Navy. Within ten years of the launching ofKaiser Franz Joseph I, the firstHabsburg-classbattleships were laid down.[25]
Despite these shortcomings,Kaiser Franz Joseph I would have a career spanning nearly 30 years.[25] In the summer of 1890, German KaiserWilhelm II invited Sterneck to participate in naval exercises in theBaltic Sea.Kaiser Franz Joseph I was dispatched along withKronprinz Erzherzog Rudolf andKronprinzessin Erzherzogin Stephanie to represent the Austro-Hungarian Navy. While under the command of Rear AdmiralJohann von Hinke, she visited Gibraltar andCowes in the United Kingdom, whereQueen Victoria reviewed the Austro-Hungarian fleet. The cruiser also made port inCopenhagen, Denmark, andKarlskrona, Sweden, before joining theGerman Imperial Navy in the Baltic for its summer exercises. Following these maneuvers,Kaiser Franz Joseph I made port in France, Portugal, Spain, Italy, andBritish Malta before returning to Austria-Hungary.[26][25]
Throughout the 1890s,Kaiser Franz Joseph I participated in several diplomatic voyages on behalf of Austria-Hungary round the world. In 1895,Kaiser Franz Joseph I and her sister ship participated in the opening ceremony of theKiel Canal.[27] Two years later, she completed her first voyage to the Far East, and returned in late 1897 to participate in aninternational demonstration off the coast of Crete. The following year, she participated in celebrations honoringVasco de Gama in Lisbon, Portugal.[28]
Following the end of the Boxer Rebellion, Austria-Hungary was granteda concession in Tianjin in December 1902 as part of its contributions to theEight-Nation Alliance. It was decided after the rebellion that the Austro-Hungarian Navy would maintain a permanent presence in the Far East to guard Austro-Hungarian interests in China, as well as provide protection for the Austro-Hungarian concession in Tianjin.Kaiserin Elisabeth would be the first Austro-Hungarian ship stationed in China following the end of the Boxer Rebellion, whileKaiser Franz Joseph I conducted training exercises in the Mediterranean Sea throughout 1903 and 1904.[29] While stationed in Austria-Hungary for training purposes,Kaiser Franz Joseph I underwent a refit in 1905 in order to have her Krupp guns replaced with 15-centimeter (5.9 in) Škoda guns. These guns were considered more modern than their predecessors, and had a faster loading time. Other changes included moving the location of the secondary guns to the upper deck, where they would be less exposed to the elements and have a better vantage points compared to their previous location in casemates located close to the waterline of both ships.[25] Later that same year, she sailed for China to relieveKaiserin Elisabeth, who underwent the same modernization upon her return to Austria-Hungary in 1906.[30]
Kaiser Franz Joseph would remain stationed in China until 1908.[29] That same year, she and her sister ship were re-classified as 2nd class cruisers and rotated duties once more, with theKaiser Franz Joseph I being sent back to China andKaiserin Elisabeth being transferred to Austria-Hungary to serve as a training vessel.[31] In 1911,Kaiser Franz Joseph I and her sister ship were again re-designated, this time as small cruisers.[25] That same year,Kaiserin Elisabeth returned to Austria-Hungary for the last time, whileKaiser Franz Joseph began her final deployment to China. During this period,Kaiser Franz Joseph's crew were deployed to protect Shanghai and Austro-Hungarian interests in China during theXinhai Revolution.[32] In 1913, the cruisers were ordered to rotate duties one final time, withKaiserin Elisabeth going to China, andKaiser Franz Joseph I returning to Austria-Hungary in 1914.[29]
Theassassination of Archduke Franz Ferdinand on 28 June 1914 inSarajevo triggered a chain of events which led to theJuly Crisis and Austria-Hungary's subsequent declaration of war onSerbia on 28 July. Events unfolded rapidly in the ensuing days. On 30 July 1914 Russia declared full mobilization in response to Austria-Hungary's declaration of war on Serbia. Austria-Hungary declared full mobilization the next day. On 1 August both Germany and France ordered full mobilization and Germany declared war on Russia in support of Austria-Hungary. While relations between Austria-Hungary and Italy had improved greatly in the two years following the 1912 renewal of theTriple Alliance,[33] increased Austro-Hungarian naval spending, political disputes over influence inAlbania, and Italian concerns over the potential annexation of land in theKingdom of Montenegro caused the relationship between the two allies to falter in the months leading up to the war. Italy declared neutrality on 1 August, citing Austria-Hungary's declaration of war on Serbia as an act of aggression, which was not covered under the Triple Alliance.[34]
By 4 August Germany had already occupiedLuxembourg and invadedBelgium after declaring war on France, and the United Kingdom had declared war on Germany in support of Belgian neutrality.[35] Following France and Britain's declarations of war on Austria-Hungary on 11 and 12 August respectively, the French AdmiralAugustin Boué de Lapeyrère was issued orders to close off Austro-Hungarian shipping at the entrance to the Adriatic Sea and to engage any Austro-Hungarian ships his Anglo-French fleet came across. Lapeyrère chose to attack the Austro-Hungarian ships blockading Montenegro. The ensuingBattle of Antivari ended Austria-Hungary's blockade, and effectively placed the Strait of Otranto firmly in the hands of Britain and France.[36][37] At the start of the war,Kaiser Franz Joseph I was assigned to the Fifth Battle Division, alongside the threeMonarch-class coastal defense ships, and the cruiserPanther at the Austro-Hungarian naval base atCattaro. Rear Admiral Richard von Barry was assigned command of this division, which was tasked with coastal defense roles.[38] After the loss of the cruiserZenta at the Battle of Antivari, Austro-HungarianMarinekommandantAnton Haus blamed Barry for failing to intercept the French forces and relieved him of command in October 1914, replacing him with Rear Admiral Alexander Hansa.[39]
Kaiser Franz Joseph I served as a harbor defense ship for most of the remainder of the war,[12] though she did see action against Montenegrin batteries atopMount Lovćen, which overshadowed theBocche di Cattaro, where she was stationed. In September 1914, a French landing party of 140 men assisted Montenegrin troops in installing eight heavy artillery pieces on the slopes of Mount Lovćen. This bolstered the artillery Montenegro had already placed on the mountain, and posed a major threat to the Austro-Hungarian base located at Cattaro. Throughout September and October, the Austro-Hungarian Fifth Division and the Franco-Montenegrin artillery dueled for control over the Bocche. The arrival of the Austro-HungarianRadetzky-classbattleships knocked out two of the French guns and forced the remainder to withdraw beyond the range of the Austro-Hungarian guns. In late November, the French withdrew and handed the guns over to Montenegro to maintain.[40] Meanwhile,Kaiser Franz Joseph I's sister ship,Kaiserin Elisabeth would be the second Austro-Hungarian warship to be sunk during the war, having been trapped in China at the outbreak of hostilities.[38] She was ultimately scuttled in early November at the German-heldKiautschou Bay concession during the Anglo-JapaneseSiege of Tsingtao.[41][1]
In late 1915, it was decided by Austria-Hungary and Germany that afterfinally conquering Serbia, Montenegro would be knocked out of the war next. On 8 January 1916,Kaiser Franz Joseph I and the other ships of the Fifth Division began a barrage which would last three days against the Montenegrin fortifications on Mount Lovćen. The sustained artillery bombardment allowed the Austro-Hungarian XIX Army Corps to capture the mountain on 11 January. Two days later, Austro-Hungarian forces entered Montenegro's capital ofCetinje, knocking Montenegro out of the war.[42][43] After the conquest of Montenegro,Kaiser Franz Joseph I remained at anchor in the Bocce di Cattaro for the remainder of the war. She almost never ventured outside of Cattaro for the next two years.[44]
By early 1918, the long periods of inactivity had begun to wear on the crews of several Austro-Hungarian ships at Cattaro, primarily those of ships which saw little combat. On 1 February, theCattaro Mutiny broke out, starting aboardSankt Georg. The mutineers rapidly gained control of most of the warships in the harbor, while others such asKaiser Franz Joseph I flew thered flag despite remaining neutral in the rebellion.[45][46] The crews of the cruisersNovara andHelgoland resisted the mutiny,[47] with the latter preparing their ship's torpedoes, but rebels aboard theSankt Georg aimed their 24 cm (9.4 in) guns atHelgoland, forcing them to back down.Novara's commander,Johannes, Prinz von Liechtenstein, initially refused to allow a rebel party to board his vessel, but after the rebel-held cruiserKaiser Karl VI trained her guns onNovara, he relented and let the crew fly ared flag in support of the mutiny. Liechtenstein and Erich von Heyssler, the commander ofHelgoland, discussed overnight how to extricate their vessels, their crews having abstained from actively supporting the rebels.[48]
The following day, many of the mutinous ships abandoned the effort and rejoined loyalist forces in the inner harbor after shore batteries loyal to the Austro-Hungarian government opened fire on the rebel-heldKronprinz Erzherzog Rudolf. Liechtenstein tore down the red flag before ordering his ship to escape into the inner harbor; they were joined by the other scout cruisers and most of the torpedo boats, followed by several of the other larger vessels. There, they were protected by shore batteries that opposed the mutiny. By late in the day, only the men aboardSankt Georg and a handful of destroyers and torpedo boats remained in rebellion. The next morning, theErzherzog Karl-class battleships arrived from Pola and put down the uprising.[49][50] In the immediate aftermath of the mutiny,Kaiser Franz Joseph I's complement was reduced to a caretaker crew while the cruiser was converted into abarracks ship. Her guns were also removed for use on the mainland.[45]
After the Cattaro Mutiny, AdmiralMaximilian Njegovan was fired as Commander-in-Chief (German:Flottenkommandant) of the Navy, though at Njegovan's request it was announced that he was retiring.[51]Miklós Horthy, who had since been promoted to commander of the battleshipPrinz Eugen, was promoted to rear admiral and named as theFlottenkommandant of the Austro-Hungarian Navy.[52]
By October 1918 it had become clear that Austria-Hungary was facing defeat in the war. With various attempts to quell nationalist sentiments failing,Emperor Karl I decided to sever Austria-Hungary's alliance with Germany and appeal to the Allied Powers in an attempt to preserve the empire from complete collapse. On 26 October Austria-Hungary informed Germany thattheir alliance was over. At the same time, the Austro-Hungarian Navy was in the process of tearing itself apart along ethnic and nationalist lines. Horthy was informed on the morning of 28 October that an armistice was imminent, and used this news to maintain order and prevent another mutiny among the fleet.[53]
On 29 October theNational Council inZagreb announced Croatia's dynastic ties to Hungary had come to a formal conclusion. The National Council also called for Croatia and Dalmatia to be unified, with Slovene and Bosnian organizations pledging their loyalty to the newly formed government. This new provisional government, while throwing off Hungarian rule, had not yet declared independence from Austria-Hungary. Thus Emperor Karl I's government in Vienna asked the newly formedState of Slovenes, Croats and Serbs for help maintaining the fleet and keeping order among the navy. The National Council refused to assist unless the Austro-Hungarian Navy was first placed under its command.[54] Emperor Karl I, still attempting to save the Empire from collapse, agreed to the transfer, provided that the other "nations" which made up Austria-Hungary would be able to claim their fair share of the value of the fleet at a later time.[55] All sailors not of Slovene, Croatian, Bosnian, or Serbian background were placed on leave for the time being, while the officers were given the choice of joining the new navy or retiring.[55][56]
The Austro-Hungarian government thus decided to hand over the bulk of its fleet to the State of Slovenes, Croats and Serbs without a shot being fired. This was considered preferential to handing the fleet to the Allies, as the new state had declared its neutrality. Furthermore, the newly formed state had also not yet publicly dethroned Emperor Karl I, keeping the possibility ofreforming the Empire into a triple monarchy alive. The transfer to the State of Slovenes, Croats and Serbs began on the morning of 31 October, with Horthy meeting representatives from the South Slav nationalities aboard his flagship,Viribus Unitis in Pola. After "short and cool" negotiations, the arrangements were settled and the handover was completed that afternoon. The Austro-Hungarian Naval Ensign was struck fromViribus Unitis, and was followed by the remaining ships in the harbor.[57] Control over the battleship, and the head of the newly-established navy for the State of Slovenes, Croats and Serbs, fell to CaptainJanko Vuković, who was raised to the rank of admiral and took over Horthy's old responsibilities as Commander-in-Chief of the Fleet.[58][56][59]
Despite the transfer, on 3 November 1918 the Austro-Hungarian government signed theArmistice of Villa Giusti with Italy, ending the fighting along theItalian Front.[60] The Armistice of Villa Giusti refused to recognize the transfer of Austria-Hungary's warships to the State of Slovenes, Croats and Serbs. As a result, on 4 November 1918, Italian ships sailed into the ports of Trieste, Pola, and Fiume. On 5 November, Italian troops occupied the naval installations at Pola. While the State of Slovenes, Croats and Serbs attempted to hold onto their ships, they lacked the men and officers to do so as most sailors who were not South Slavs had already gone home. The National Council did not order any men to resist the Italians, but they also condemned Italy's actions as illegitimate. On 9 November, Italian, British, and French ships sailed into Cattaro and seized the remaining Austro-Hungarian ships, includingKaiser Franz Joseph I, which had been turned over to the National Council. At a conference atCorfu, the Allied Powers agreed the transfer of Austria-Hungary's Navy to the State of Slovenes, Croats and Serbs could not be accepted, despite sympathy from the United Kingdom. Faced with the prospect of being given an ultimatum to hand over the former Austro-Hungarian warships, the National Council agreed to hand over all the ships transferred to them by the Austro-Hungarian Empire, to includeKaiser Franz Joseph I, beginning on 10 November 1918.[61]
While Cattaro remained under Allied occupation after the war,Kaiser Franz Joseph I remained under the administration of France as it would not be until 1920 when the final distribution of the ships was settled among the Allied powers under the terms of theTreaty of Saint-Germain-en-Laye. While under French control, she was converted into an ammunition ship, but sank while moored in the Bocche di Cattaro during a heavy gale on 17 October 1919. Her sinking was attributed to several open hatches and her top-heaviness due to the ammunition stored aboard.[45] In 1922, a Dutch salvage company discovered theKaiser Franz Joseph I and began salvaging operations. Some of her fittings, including her deck cranes, were ultimately salvaged, though most of the ship remained intact at the bottom of the bay. In 1967, the Yugoslav salvage company Brodospas salvaged the wreck as well.[45]
