SMS Tátra

SMS Tátra was the lead ship of her class of six destroyers built for the kaiserliche und königliche Kriegsmarine (Austro-Hungarian Navy) shortly before the First World War. 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 Tátra was one of the ships conducting raids off the Albanian coast to interdict the supply lines between Italy and Albania. During the early stages of the 1st Battle of Durazzo in late December, the ship was tasked to tow her one of her sister ships that had been crippled by a mine. She was forced to abandon her sister when the Austro-Hungarians were spotted by a strong force of Allied ships and had to evade their pursuit. Tátra participated in several unsuccessful raids on the Otranto Barrage in 1917. She was transferred to Italy in 1920 in accordance with the peace treaties ending the war and renamed Fasana. The Regia Marina (Royal Italian Navy) used her for spare parts; she was discarded in 1923 and subsequently scrapped.

Design and description
The Tátra-class destroyers were faster, more powerfully armed and more than twice as large as the preceding Huszár-class destroyer. The ships had an overall length of 83.5 m, a beam of 7.8 m, and a maximum draft of 3 m. They displaced 870 LT at normal load and 1050 LT at deep load. The ships had a complement of 105 officers and enlisted men.

The Tátras were powered by two AEG-Curtiss steam turbine sets, each driving a single propeller shaft using steam provided by six Yarrow boilers. Four of the boilers were oil-fired while the remaining pair used coal. The turbines, designed to produce 20600 shp, were intended to give the ships a speed of 32.5 kn. The ships carried enough oil and coal to give them a range of 1600 nmi at 12 kn.

The main armament of the Tátra-class destroyers consisted of two 50-caliber Škoda Works 10 cm K10 guns, one each fore and aft of the superstructure in single mounts. Their secondary armament consisted of six 45-caliber 66 mm guns, two of which were on anti-aircraft mountings. They were also equipped with four 450 mm torpedo tubes in two twin rotating mountings amidships.

Construction and career
Tátra was laid down by Ganz-Danubius at their shipyard in Porto Ré in the Kingdom of Croatia-Slavonia of the Austro-Hungarian Empire on 19 October 1911, launched on 4 November 1912 and completed on 18 October 1913. 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. From 21 November to 9 December, Triglav had her propeller shaft bearings replaced.

Action off Vieste
The Kingdom of Italy signed a secret treaty in London in late April 1915 breaking its 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 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 Pelagosa and the Italian coast, four days prior to the Italian declaration of war on 23 May, were four Tátra-class destroyers, including Tátra, and the cruiser SMS Helgoland (1912). 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 Nembo-class destroyers, ITALIAN DESTROYER Turbine and ITALIAN DESTROYER Aquilone, but they were believed by the Italians to be friendly ships in the darkness.

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. The ship 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, Linienschiffskapitän (Captain) Heinrich Seitz, the destroyers SMS Csepel and 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 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. As they were withdrawing they were engaged by the protected cruiser ITALIAN CRUISER Libia and the 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.

Tátra bombarded Pelagosa two days after it had been occupied by the Italians on 11 July. Twelve days later, Helgoland and her sister SMS Saida, escorted by Tátra, Csepel, 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 telegraph cable in Tremiti. On 28 July, all six Tátra-class ships and the same pair of cruisers, reinforced by the German submarine SMU UB-14, 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.

The Bulgarian declaration of war on Serbia on 14 October cut the existing supply line from Serbia to Salonika, Greece, and forced the Allies to begin supplying Serbia through ports in 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 Austro-Hungarian High Command (Armeeoberkommando) on 29 November to patrol the Albanian coast and to disrupt Allied troop movements caused him to transfer Helgoland, her sister SMS Novara (1913) and the Tátra-class ships to Cattaro. On 6 December, Helgoland and the Tátras swept down the coast to Durazzo, sinking five motor schooners, including two in Durazzo harbor.

1st Battle of Durazzo
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) 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 FRENCH SUBMARINE Monge at 02:35. 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 75 mm 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 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. Tátra was finally successful in securing a tow at 09:30, while also rescuing the ship's executive officer and 33 seamen, but was limited to a speed of 6 kn 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 boats were en route to support him.

Italian observers had spotted Seitz's ships at 07:00 and the Allied quick-reaction force of the British light cruiser HMS Dartmouth (1910) and the Italian scout cruiser ITALIAN CRUISER Quarto, escorted by five French destroyers, sortied 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 ITALIAN CRUISER Nino Bixio, the British light cruiser HMS Weymouth (1911) and four Italian destroyers. Seitz had ordered Triglav's crew taken off before any of the columns of smoke from these ships were spotted by his ships and he ordered Tátra to drop her tow at 13:15 and abandon Triglav. Five minutes later the Austro-Hungarian ships were spotted and the French destroyers were ordered to deal with Triglav at 13:38 while the cruisers pursued Seitz's ships.

Seitz turned southwest at 29 kn to put as much distance between his ships and their pursuers although Dartmouth opened fire at her maximum range of 14000 yd at 13:43 and scored her first hit on Helgoland twelve minutes later. The destroyers were generally not engaged during this battle, being further away, although Csepel was hit once with little effect. Despite further hits on the cruiser which reduced her speed to 27 kn the Austro-Hungarians were able to disengage before reaching the Italian coast when darkness fell around 17:30. Tátra had a machinery breakdown at 18:45 that reduced her speed to 20 kn, but she reached Šibenik safely with the rest of Seitz's ships.

On 4 July 1916 Helgoland, Tátra, Orjen and Balaton raided the barrage, but could not find any targets in the poor visibility. Tátra was refitting 1–31 December in Pola and had a pair of boilers replaced. On the night of 11/12 March 1917, Tátra, Orjen, Csepel and Balaton swept through the Strait of Otranto, but failed to sink the French cargo ship SS Gorgone that they encountered. Tátra did not directly participate in the Battle of the Strait of Otranto on 14–15 May, but was one of the reinforcing ships that caused the Allied ships to break off the action. The ship was returned to Pola on 26 May for a refit that lasted until 13 August; it included replacing a boiler. Helgoland and all of the Tátras 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, Tátra, Balaton and Csepel 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 moorings which did nothing to improve the morale of their crews. On 1 February 1918, the Cattaro Mutiny broke out, starting aboard the armored cruiser SMS Sankt Georg. 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. Tátra'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. The scout cruisers and Tátra, 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 Erzherzog Karl-class battleships arrived from Pola and put down the uprising.

The ship was based in Pola from 7 April to 6 June and returned to Cattaro the following day in preparation for an attack on the Otranto Barrage by the bulk of Austro-Hungarian Fleet on 10 June. The operation was canceled after the battleship SMS Szent István was sunk by Italian motor torpedo boats as she steamed south to rendezvous with the forces in Cattaro. Tátra and Orjen provided security to the hospital ship SS Oceania that had run aground on 13 October. Tátra transported Seitz to Pola on 30 October.

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 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.

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.

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 rejected Emperor Karl I, keeping the possibility of reforming the Empire into a triple monarchy alive.

Post-war
On 3 November the Austro-Hungarian government signed the Armistice of Villa Giusti with Italy, ending the fighting along the Italian Front, 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. 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.

On 23 March 1919, the Italians sailed the ship to Venice together with several other former Austro-Hungarian warships and displayed them in a victory parade the following day. When the Allies divided up the Austro-Hungarian Fleet amongst themselves in January 1920, Tátra was awarded to Italy. She was renamed Fasana on 27 September and towed to Pola on 16 October to provide spare parts for her sisters. The ship was discarded on 5 July 1923 and subsequently scrapped.
