Completed in 1913, she helped to sink an Italian destroyer during the [[action off Vieste]] in May 1915 after Italy declared war on Austria-Hungary. Two months later the ship participated in an unsuccessful attempt to recapture a small island in the central [[Adriatic Sea]] from the Italians. In November and early December ''Csepel'' was one of the ships conducting raids off the [[Albania]]n coast to interdict the supply lines between Italy and Albania. She was hit one time during the [[Battle of Durazzo (1915)|First Battle of Durazzo]] in late December. Her stern was blown off by a French submarine in early 1916 and her repairs were not completed until early 1917.

''Csepel'' participated in several unsuccessful raids on the [[Otranto Barrage]] in 1917, although she sank an Italian destroyer during the [[Battle of the Strait of Otranto (1917)|Battle of the Strait of Otranto]]. During the [[action of 22 April 1918]] in the [[Strait of Otranto]], the ship helped to damage a pair of British destroyers. She was transferred to Italy in 1920 in accordance with the peace treaties ending the war and renamed '''''Muggia'''''. The {{lang|it|[[Regia Marina]]}} (Royal Italian Navy) transferred her to the [[Far East]] in 1927 where she [[Ship grounding|ran aground]] and was wrecked during a [[typhoon]] two years later.

== Design and description== The ''Tátra''-class destroyers were faster, more powerfully armed and more than twice as large as the preceding {{sclass|Huszár|destroyer|4}}. The ships had an [[length overall|overall length]] of {{convert|83.5|m|ftin|sp=us}}, a [[beam (nautical)|beam]] of {{convert|7.8|m|ftin|sp=us}}, and a maximum [[draft (hull)|draft]] of {{convert|3|m|ftin|sp=us}}.<ref name=s8>Sieche 1985a, p. 338</ref> They [[Displacement (ship)|displaced]] {{convert|870|LT|t}} at normal load and {{convert|1050|LT|t}} at [[deep load]].<ref name=g4>Greger, p. 44</ref> The ships had a complement of 105 officers and enlisted men.<ref name=s8/>

The ''Tátra''s were powered by two [[AEG (German company)|AEG]]-Curtiss [[steam turbine]] sets, each driving a single [[propeller shaft]] using steam provided by six [[Yarrow boiler]]s. Four of the boilers were [[fuel oil|oil]]-fired while the remaining pair used coal. The turbines, designed to produce {{convert|20600|shp|kW|lk=on}}, were intended to give the ships a speed of {{convert|32.5|kn|lk=on}}. The ships carried enough oil and coal to give them a range of {{convert|1600|nmi|lk=in}} at {{convert|12|kn}}.<ref name=g4/>

The main armament of the ''Tátra''-class destroyers consisted of two 50-[[caliber (artillery)|caliber]] [[Škoda Works]] [[Škoda 10 cm K10|{{convert|10|cm|in|sp=us|adj=on|1}} K10]] guns, one each fore and aft of the [[superstructure]] in single, unprotected mounts. Their [[secondary armament]] consisted of six 45-caliber [[Škoda 7 cm guns|{{convert|66|mm|in|sp=us|adj=on|1}}]] guns, two of which were on [[anti-aircraft]] mountings. They were also equipped with four {{convert|450|mm|in|sp=us|adj=on|1}} [[torpedo tube]]s in two twin rotating mountings [[amidships]].<ref>Noppen, p. 48</ref>

==Construction and career== ''Csepel'' was [[laid down]] by [[Ganz-Danubius]] at their [[Kraljevica Shipyard|shipyard]] in [[Porto Ré]] in the [[Kingdom of Croatia-Slavonia]] of the [[Austro-Hungarian Empire]] on 9 January 1912, [[Ceremonial ship launching|launched]] on 30 December 1912 and completed on 29 December 1913.<ref name=g4/> The ''Tátra''-class ships did not play a significant role in the minor raids and skirmishing in the Adriatic in 1914 and early 1915 between the [[Entente Cordiale]] and the [[Central Powers]].<ref>Cernuschi & O'Hara, p. 168</ref> On 13 August 1914, ''Csepel'' rescued 76 survivors and pulled 18 bodies from the water from the Austro-Hungarian [[passenger ship]] {{SS|Baron Gautsch}} after it had blundered into a [[minefield (disambiguation)|minefield]] and sunk. The destroyer had her propeller shaft [[bearing (mechanical)|bearing]]s replaced from 9 to 12 May 1915.<ref>Bilzer, pp. 116–117</ref>

===Action off Vieste=== {{main|Action off Vieste}} The [[Kingdom of Italy]] signed a [[Treaty of London (1915)|secret treaty in London]] in late April 1915 breaking its [[Triple Alliance (1882)|alliance]] with the [[German Empire]] and Austro-Hungary and promising to declare war on the Central Powers within a month. Austro-Hungarian intelligence discovered this and Admiral [[Anton Haus]], commander of the Austro-Hungarian Navy, planned a massive surprise attack on Italian ports and facilities on the northern Adriatic coast, outside of interception range of the modern ships of the {{lang|it|Regia Marina}} stationed at [[Taranto]]. To warn of any Italian warships able to interfere with the bombardments, Haus prepositioned three groups of destroyers, each led by a [[scout cruiser]]. Placed in the central Adriatic between the island of [[Palagruža|Pelagosa]] and the Italian coast, four days prior to the Italian declaration of war on 23 May, were four ''Tátra''-class destroyers, including ''Csepel'', and the cruiser {{SMS|Helgoland|1912|6}}. Around midnight on the night of 23/24 May, Haus ordered the reconnaissance groups to move west and attack Italian coastal targets. About an hour later the four Tátras encountered a pair of Italian {{sclass|Nembo|destroyer}}s, {{ship|Italian destroyer|Turbine|1901|2}} and {{ship|Italian destroyer|Aquilone|1902|2}}, but in the darkness they were believed by the Italians to be friendly ships.<ref>Noppen, pp. 54–55; O'Hara & Heinz, pp. 153–154</ref>

The Italian ships separated when ''Aquilone'' went to investigate a sighting; ''Helgoland'' began bombarding the city of [[Barletta]] at 04:00 and the Italian destroyer spotted the cruiser at 04:38. ''Aquilone'' turned away to the southeast and was able to disengage without any damage. ''Turbine'', however, encountered ''Helgoland'' several minutes later and believed that she was an Italian ship until she was disabused by a [[salvo]] from the cruiser. The destroyer turned to the north, towards [[Vieste]], to escape, with ''Helgoland'' and the destroyer {{SMS|Orjen}} in pursuit. Alerted by ''Helgoland''{{'}}s commander, {{lang|de|[[Linienschiffskapitän]]}} (Captain) Heinrich Seitz, the destroyers ''Csepel'' and {{SMS|Tátra}}, which had been bombarding [[Manfredonia]], moved to intercept and spotted ''Turbine'' at 05:10, opening fire at 05:45. {{SMS|Lika}}, which had been bombarding Vieste, was ordered to block her escape to the north while ''Helgoland'' stayed to the east to cut off her access to the Adriatic. ''Lika'' scored the critical hit of the battle when one of her 66-millimeter shells broke ''Turbine''{{'}}s steam pipe and caused her to rapidly lose speed. ''Tátra'' and ''Helgoland'' also scored hits and ''Turbine'' was dead in the water with a [[list (watercraft)|list]] when her crew abandoned ship at 06:51. She had hit ''Tátra'' and ''Csepel'' during the engagement, but failed to inflict any significant damage. The Austro-Hungarians rescued 35 survivors before torpedoing the derelict ship. As they were withdrawing they were engaged by the [[protected cruiser]] {{ship|Italian cruiser|Libia||2}} and the [[Armed merchantman#Armed merchant cruisers|armed merchant cruiser]] {{SS|Cittá di Siracusa}} between 07:10 and 07:19. ''Helgoland'' was struck by one shell before they were able to disengage from the slower ships.<ref>Noppen, pp. 56–57; O'Hara & Heinz, pp. 154–155</ref>

On 23 July ''Helgoland'' and her sister {{SMS|Saida|1912|6}}, escorted by ''Csepel'', ''Tátra'', their sister {{SMS|Balaton}} and three other destroyers bombarded the towns of [[Termoli]], [[Ortona]] and [[San Benedetto del Tronto]] while a [[landing party]] cut the [[Submarine communications cable|telegraph cable]] in [[Tremiti]]. Five days later, all six ''Tátra''-class ships and the same pair of cruisers, reinforced by the German submarine {{SMU|UB-14||2}}, attempted to recapture Pelagosa. Despite a heavy bombardment by the ships, the 108-man landing party was unable to overcome the 90-man [[garrison]] and was forced to withdraw.<ref>Cernuschi & O'Hara 2015, p. 169; Halpern 1994, pp. 148–150</ref>

The [[Kingdom of Bulgaria|Bulgarian]] declaration of war on [[Kingdom of Serbia|Serbia]] on 14 October cut the existing supply line from Serbia to [[Thessaloniki|Salonika]], [[Kingdom of Greece|Greece]], and forced the [[Allies of World War I|Allies]] to begin supplying Serbia through ports in [[Principality of Albania|Albania]]. This took about a month to work out the details and the Austro-Hungarians took just about as long to decide on a response. Haus ordered Seitz to take ''Helgoland'', ''Saida'' and all six ''Tátra''-class destroyers on a reconnaissance mission off the Albanian coast on the night of 22/23 November. They encountered and sank a small [[cargo ship]] and a motor [[schooner]] carrying flour for Serbia; four Italian destroyers were unable to intercept them before they reached friendly territory. Haus was initially reluctant to send his ships so far south, but an order from the {{lang|de|[[Armeeoberkommando]]}} (High Command) on 29 November to patrol the Albanian coast and to disrupt Allied troop movements caused him to transfer ''Helgoland'', her sister {{SMS|Novara|1913|6}} and the ''Tátra''-class ships to [[Cattaro]]. On 6 December, ''Helgoland'' and the ''Tátra''s swept down the coast to [[Durazzo]], sinking five motor schooners, including two in Durazzo harbor.<ref>Cernuschi & O'Hara 2015, pp. 165, 169; Halpern 1994, pp. 153–154</ref>

===First Battle of Durazzo=== {{main|Battle of Durazzo (1915)}} Austro-Hungarian aircraft spotted a pair of Italian destroyers in Durazzo harbor on 28 December and Haus dispatched Seitz to take ''Helgoland'', ''Tátra'', ''Csepel'', ''Lika'', ''Balaton'' and their sister {{SMS|Triglav|1913|6}} south and search the area between Durazzo and [[Brindisi]] for them. If they were not found he was to arrive at Durazzo at dawn and destroy any ships found there. Seitz's ships sailed later that day and sank the {{ship|French submarine|Monge|1908|6}} at 02:35; ''Csepel'' rescued seven survivors. He was unable to find the destroyers and dutifully arrived off Durazzo at dawn. At 07:30 he ordered four of his destroyers into the harbor to sink the cargo ship and two schooners anchored there while ''Helgoland'' engaged the [[coastal artillery]] defending the port. A well-camouflaged {{convert|75|mm|adj=on|sp=us|0}} [[artillery battery]] opened fire at 08:00 at [[point-blank range]]. While maneuvering to avoid its fire, ''Lika'' and ''Triglav'' entered a minefield. After striking two mines in quick succession, ''Lika'' sank at 08:03 and ''Triglav'' was crippled when her [[Fire room|boiler rooms]] flooded after hitting one mine. After she was maneuvered out of the minefield, ''Csepel'' attempted to pass a towline, but it got tangled in one of her own propellers, badly damaging it and limited her to {{convert|20|kn}}. ''Tátra'' was finally successful in securing a tow at 09:30, but was limited to a speed of {{convert|6|kn|spell=in}} when Seitz led his ships northwards. He radioed for assistance at 10:35 and was informed an hour later that the [[armored cruiser]] {{SMS|Kaiser Karl VI}} and four [[torpedo boat]]s were en route to support him.<ref>Bilzer, p. 118; Cernuschi & O'Hara 2015, pp. 165, 169; Halpern 1994, pp. 155–157; Noppen, pp. 60–61; O'Hara & Heinz, pp. 157–158</ref>

[[File:Csepel NH87669.jpg|thumb|''Csepel'' on the right, followed by ''Balaton'' and ''Tátra'', returning after the 1st Battle of Durazzo, 30 December 1915]] Italian observers had spotted Seitz's ships at 07:00 and the Allied [[quick-reaction force]] of the British [[light cruiser]] {{HMS|Dartmouth|1910|6}}, commanded by [[Captain (Royal Navy)|Captain]] [[Percy Addison]], and the Italian scout cruiser {{Ship|Italian cruiser|Quarto||2}}, escorted by five French destroyers, [[sortie]]d in an attempt to cut off the Austro-Hungarian ships from their base at Cattaro. These were followed two hours later by the Italian scout cruiser {{Ship|Italian cruiser|Nino Bixio||2}}, the British light cruiser {{HMS|Weymouth|1911|6}} and four Italian destroyers. Seitz ordered ''Triglav'' to be abandoned at 13:15 once the smoke from these ships had been spotted and for ''Csepel'' to turn to the south then southwest while the main body briefly covered her before turning southwest themselves. The French destroyers were ordered to deal with ''Triglav'' at 13:38 while the cruisers pursued Seitz's ships.<ref>Cernuschi & O'Hara 2015, p. 165; Halpern 1994, pp. 156–157; Noppen, p. 61; O'Hara & Heinz, pp. 157–159</ref>

''Quarto''{{'}}s [[captain (nautical)|captain]] initially positioned his ship in trail behind ''Dartmouth'', thinking to cut-off ''Csepel'', but Addison ordered ''Quarto'' to fall in on ''Dartmouth''{{'}}s port quarter around 14:15, away from ''Csepel''. He ordered the Italian ship to pursue ''Csepel'' fifteen minutes later, but by then the destroyer had increased her speed to {{convert|26|kn}}. ''Quarto'' opened fire at a range of {{convert|8750|yd|m|order=flip|sp=us}} at 14:40 and the Austro-Hungarian ship started [[zigzag]]ging to throw off ''Quarto''{{'}}s fire. She only fired 23 times by 15:08 and managed to hit ''Csepel'' once, inflicting little damage. The destroyer managed to rejoin Seitz's main body about 16:45 and the Austro-Hungarians were able to disengage before reaching the Italian coast when darkness fell around 17:30.<ref>Cernuschi & O'Hara 2015, pp. 165, 169; Halpern 1994, p. 157; Noppen, pp. 61–62; O'Hara & Heinz, pp. 158–161</ref>

[[File:Csepel NH87671.jpg|thumb|''Csepel'' being towed into Cattaro on 4 May 1916 after being torpedoed]] On 27 January 1916, ''Novara'', ''Csepel'' and ''Orjen'' departed Cattaro on a mission to attack the shipping in Durazzo harbor. En route the two sisters accidentally collided with each other and had to return to port although the cruiser continued the mission. ''Csepel'' was under repair until 21 April. On 4 May, the {{ship|French submarine|Bernoulli||6}} torpedoed the destroyer off Cattaro and blew off her stern. She was towed to port for emergency repairs and was then towed to [[Fiume]] for permanent repairs on 13–16 May. On 3 June, ''Csepel'' was moved to Porto Ré where she was fitted with a replacement stern taken from one of the {{sclass|Ersatz Triglav|destroyer|0}} under construction. After [[Glossary of nautical terms (M-Z)#working up|working up]], the ship returned to Cattaro on 31 October. On the night of 11/12 March 1917, ''Balaton'', ''Orjen'', ''Csepel'' and ''Tátra'' swept through the Strait of Otranto, but failed to sink the French cargo ship {{SS|Gorgone}} that they encountered.<ref>Bilzer, p. 117; Cernuschi & O'Hara 2015, p. 169; Cernuschi & O'Hara 2016, p. 67; Halpern 2004, p. 79; O'Hara & Heinz, p. 200</ref>

===Battle of the Strait of Otranto=== {{main|Battle of the Strait of Otranto (1917)}} On the night of 14/15 May, ''Balaton'' and ''Csepel'' departed Cattaro with orders to search off the Albanian coast and the Strait of Otranto for Allied shipping. They were intended to act as a diversion for the attack by the three {{sclass|Novara|cruiser|0}} scout cruisers on the Otranto Barrage. The destroyers encountered a convoy of three merchant ships, escorted by the {{ship|Italian destroyer|Borea|1902|6}}, at 03:10. ''Csepel'' lit up ''Borea'' with her [[searchlight]] at 03:24 and opened fire immediately afterward, hitting the Italian ship four times in rapid succession. One of the hits broke her main steam pipe which caused her to slow to a stop and the others set her on fire; she sank shortly before dawn. ''Balaton'' fired at the {{GRT|1657|disp=long}} {{SS|Carroccio}} which blew up when her cargo of ammunition exploded. The destroyers engaged the other two ships, setting one on fire and slightly damaging the other one, after which they disengaged and headed north at {{convert|25|kn}}.<ref>Cernuschi & O'Hara 2016, pp. 62–63, 67; Halpern, pp. 162–163; Noppen, pp. 69, 71; O'Hara & Heinz, pp. 260, 262</ref>

Italian observers reported this action at 03:48 and the patrolling Italian scout cruiser {{ship|Italian cruiser|Carlo Mirabello||2}} and her escorting trio of French destroyers were alerted at 04:35 and turned south to intercept. They did not spot the Austro-Hungarian ships, but another group of Allied ships did at 07:45. This group consisted of two British light cruisers, the brand-new Italian scout cruiser {{ship|Italian cruiser|Aquila||2}} and four Italian destroyers under the command of [[Rear Admiral]] [[Alfredo Acton]]. He ordered ''Aquila'' and the destroyers to investigate five minutes later as the Austro-Hungarian ships turned away towards Durazzo. The scout cruiser was the fastest ship in the Italian fleet and she opened fire at 08:15 at a range of {{convert|12500|yd|m|order=flip|sp=us}} while closing the range to {{convert|10500|yd|m|order=flip|sp=us}} before ''Csepel'' hit her once at 08:32; severing her main steam line, killing seven men and causing her to lose power. The destroyers continued the pursuit, but broke off when shells from Durazzo's coastal artillery began dropping around them about 09:05. After the Italian ships moved to rejoin Acton's force at 09:18, ''Balaton'' and ''Csepel'' turned towards Cattaro, evading an attack by ''Bernoulli'' en route. During the battle, ''Csepel'' fired 127 rounds from her main guns, 78 shells from her secondary armament and two torpedoes.<ref>Cernuschi & O'Hara 2016, p. 63; Halpern 1994, p. 163; Noppen, p. 71; O'Hara & Heinz, pp. 263–264, 269</ref>

''Helgoland'' and all of the ''Tátra''s attempted to duplicate the success of the earlier raid on 18–19 October, but they were spotted by Italian aircraft and turned back in the face of substantial Allied reinforcements alerted by the aircraft. On the night of 13 December, ''Csepel'', ''Tátra'' and ''Balaton'' raided the Otranto Barrage, but disengaged after firing torpedoes at what they believed to be four Allied destroyers, although there is no record of any attacks that night in Allied records.

The smaller ships in the Austro-Hungarian Navy were the most active ones and their crews had the highest morale; most of the larger ships did little but swing on their [[Mooring (watercraft)|moorings]] which did nothing to improve the morale of their crews. On 1 February, the [[Cattaro Mutiny]] broke out, starting aboard the armored cruiser {{SMS|Sankt Georg||2}}. The mutineers rapidly gained control of ''Kaiser Karl VI'' and most of the other major warships in the harbor. Unhappy with the failure of the smaller ships' crews to join the mutiny, the mutineers threatened to fire at any ship that failed to hoist a [[red flag (politics)|red flag]]. ''Csepel''{{'}}s crew hoisted a flag with the permission of her captain with the proviso that there should be no disturbances aboard ship. The following day, many of the mutinous ships abandoned the effort after [[coast-defense guns]] loyal to the government opened fire on the rebel [[guard ship]] {{SMS|Kronprinz Erzherzog Rudolf||2}}. The scout cruisers and ''Csepel'', among other ships, took advantage of the confusion to rejoin loyalist forces in the inner harbor where they were protected by coastal artillery. The next morning, the {{sclass|Erzherzog Karl|battleship|1}}s arrived from [[Pula|Pola]] and put down the uprising. The destroyer was refitted in Pola from 7 to 20 April.<ref>Bilzer, p. 118; Halpern 2004b, pp. 48–50, 52–53; Sondhaus 1994, p. 322</ref>

===Action of 22 April 1918=== On the night of 22–23 April 1918, ''Csepel'' and all four {{sclass|Ersatz Tátra|destroyer|2}}s attempted to intercept Allied shipping in the Strait of Otranto. They were spotted by the pair of British destroyers, {{HMS|Jackal|1911|2}} and {{HMS|Hornet|1911|2}}, which were patrolling the western side of the Strait. The British ships altered course to intercept them. At a range of about {{convert|3000|yd|m|order=flip|sp=us}} the leading Austrian destroyer opened fire. The British ships reversed course and began laying a [[smoke screen]] hoping to lure the Austrians further south. The Austrians began hitting their targets quickly with ''Jackal'' slightly damaged by three hits, but ''Hornet'' was badly damaged by hits that caused a fire and subsequent explosion in her forward [[magazine (artillery)|magazine]] and jammed her steering so that she began turning circles. Their return fire was ineffective, but the Austrians disengaged after about 15 minutes, pursued by ''Jackal''. The other four destroyers of the patrol had steamed towards the battle and they joined the pursuit for a couple of hours before turning away about {{convert|20|nmi}} from Cattaro. ''Csepel'' received an extensive refit from 13 June to 7 October in Pola. She returned to Cattaro the following day, but was back in Pola by the war's end.<ref>Bilzer, p. 118; Cernuschi & O'Hara 2016, pp. 68, 71; Halpern 2004, pp. 137–140; Noppen, p. 80; O'Hara & Heinz, p. 284</ref>

===End of the war=== By October 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 Allies in an attempt to preserve the empire from complete collapse. On 26 October Austria-Hungary informed Germany that [[Dual Alliance (1879)|their alliance]] was over. At the same time, the Austro-Hungarian Navy was in the process of tearing itself apart along ethnic and nationalist lines. Vice Admiral [[Miklós Horthy]] was informed on the morning of 28 October that an armistice was imminent, and used this news to maintain order and prevent a mutiny among the fleet. While a mutiny was spared, tensions remained high and morale was at an all-time low.<ref>Sondhaus 1994, pp. 350–351</ref>

The following day the [[State of Slovenes, Croats and Serbs#National Council|National Council]] in [[Zagreb]] announced Croatia's dynastic ties to Hungary had come to an end. This new provisional government, while throwing off Hungarian rule, had not yet declared independence from Austria-Hungary. Thus Emperor Karl&nbsp;I's government in Vienna asked the newly formed State of Slovenes, Croats and Serbs for help maintaining the fleet stationed at Pola and keeping order among the navy. The National Council refused to assist unless the Austro-Hungarian Navy was first placed under its command. Emperor Karl&nbsp;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. 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.<ref>Sokol, pp. 136–137, 139; Sondhaus 1994, pp. 351–352</ref>

The Austro-Hungarian government thus decided to hand over the bulk of its fleet, preferring to do that rather than give the fleet to the Allies, as the new state had declared its neutrality. Furthermore, the newly formed state had also not yet publicly repudiated Emperor Karl&nbsp;I, keeping the possibility of [[Trialism in Austria-Hungary|reforming the Empire into a triple monarchy]] alive.<ref>Halpern 1994, p. 177; Sokol 1968, pp. 136–137, 139; Sondhaus 1994, pp. 353–354</ref>

===Post-war=== On 3 November the Austro-Hungarian government signed the [[Armistice of Villa Giusti]] with Italy, ending the fighting along the [[Italian Front (World War I)|Italian Front]],<ref>Sieche 1985a, p. 329</ref> although it refused to recognize the transfer of Austria-Hungary's warships. As a result, on 4 November, Italian ships sailed into the ports of [[Trieste]], Pola, and Fiume and Italian troops occupied the naval installations at Pola the following day. The National Council did not order any men to resist the Italians, but they also condemned Italy's actions as illegitimate. On 9 November, all remaining ships in Pola harbour had the Italian flag raised. At a conference at [[Corfu]], the Allies agreed the transfer could not be accepted, despite sympathy from the United Kingdom.<ref>Sieche 1985b, pp. 137–140</ref> Faced with the prospect of being given an ultimatum to surrender the former Austro-Hungarian warships, the National Council agreed to hand over the ships beginning on 10 November.<ref>Sondhaus 1994, pp. 357–359</ref> When the Allies divided up the Austro-Hungarian Fleet amongst themselves in January 1920, ''Csepel'' was awarded to Italy. She was commissioned in the ''Regia Marina'' with the name ''Muggia'' on 26 September and transferred to [[Shanghai]], China, in March 1927. The ship ran aground and was wrecked on the [[Finger Rocks]] near [[Hea Chu Island]] near [[Amoy]], in dense fog and darkness, or during a typhoon, on 25 March 1929. The 77 survivors were rescued from rocks by the Japanese oiler {{ship||Matsumoto Maru}} after the fog lifted on 26 March.<ref>Bilzer, pp. 118, 121; Greger, p. 47; Noppen, p. 85</ref><ref>{{cite web |url=http://www.combinedfleet.com/Matsumoto_t.htm |title=Matsumoto Maru: Tabular Record of Movement |work=Yusosen! |edition=Revised |publisher=Combinedfleet.com |orig-date=2009 |date=2018 |last1=Hackett |first1=Bob |last2=Cundall |first2=Peter |name-list-style=amp |access-date=27 December 2022}}</ref>
