Background and description

The loss of two Tátra-class destroyers in the 1st Battle of Durazzo in 1915 caused the Austro-Hungarian Navy to begin construction of four improved versions of the Tátras the following year.

The Ersatz Triglav-class ships were slightly longer than the Tátras with an

deep load.[1] The ships had a complement of 114 officers and enlisted men.[2]

The destroyers were powered by two

kW), were intended to give the ships a speed of 32.6 knots (60.4 km/h; 37.5 mph). The ships carried enough oil and coal to give them a range of 500 nautical miles (930 km; 580 mi) at full speed.[2][3]

The main armament of the Ersatz Triglav-class destroyers consisted of two

anti-aircraft mountings. They were also equipped with four 450-millimeter (17.7 in) torpedo tubes in two twin rotating mountings aft of the funnels. Two spare torpedoes were stored on the main deck.[3]

Construction and service

The four Ersatz Triglav-class destroyers were ordered on 19 January 1916.

Ganz-Danubius on 24 August 1916. The ship was launched on 24 February 1917 and completed on 21 July that year.[5]

First World War

On 19 November 1917, Triglav, together with the destroyer

On the night of 22/23 April 1918, Triglav, together with the destroyers Csepel, Dukla, Lika and Uzsok, under the command of Fregattenkapitän Karl Herkner aboard Triglav, carried out a raid into the Strait of Otranto with the objective of attacking shipping between Italy and Albania. They encountered the patrolling British destroyers Hornet and Jackal, and opened fire on the British ships after Hornet challenged the Austro-Hungarian ships. Both British ships were hit, with Hornet suffering a magazine explosion and a jammed rudder, but Herkner broke off the engagement after about 15 minutes, as Allied reinforcements were likely to arrive soon. Jackal pursued the retiring Austro-Hungarian ships and was joined by the British destroyer Alarm, the Australian Torrens and the French Cimeterre, but the faster Austro-Hungarian ships pulled away from the Allied destroyers and escaped unharmed.[8] In June 1918, Rear Admiral Miklós Horthy, Commander-in-Chief of the Austro-Hungarian fleet, planned a large-scale attack by the Austro-Hungarian Fleet against the Otranto Barrage. Triglav, together with her three sister-ships and the cruisers Novara and Helgoland, were to attack between Fano and Santa Maria di Leuca, while a second group consisting of the cruisers Admiral Spaun and Saida and four torpedo-boats would attack near Otranto, with the Austro-Hungarian battleships deployed to engage any Allied ships that sortied in response. The operation was cancelled, however, when the battleship Szent István was sunk by an Italian motor torpedo boat early on 10 June.[4][9][10]

End of the war

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 Allies in an attempt to preserve the empire from complete collapse. On 26 October Austria-Hungary informed Germany that 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.[11]

The following day the 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 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 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.[12]

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 dethroned Emperor Karl I, keeping the possibility of reforming the Empire into a triple monarchy alive.[13]

Post-war

On 3 November the Austro-Hungarian government signed the

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.[15] 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.[16] When the Allies divided up the Austro-Hungarian Fleet amongst its members in January 1920, Triglav was awarded to Italy. She was commissioned in the Regia Marina with the name Grado in September and was discarded and subsequently scrapped on 30 September 1937.[17]
