two Italian MAS (motor torpedo boats) managed to penetrate the harbour defences undetected and fired several torpedoes at the two ships. Wien was struck by two torpedoes and sank in less than five minutes with the loss of 46 of her crew. 1918 On 13 February, the submarine (Audry) was lost with all hands after hitting a mine off the Bocche di Cattaro. On 22/23 April, the Austro-Hungarian s , , , SMS Lika and SMS Csepel encountered the British destroyers and , the Australian and the French . HMS Hornet was badly damaged in the ensuing fight but the alarm went up and the Austrians turned for home, pursued by Jackal, who had lost her mainmast. The Premuda attack At 03:30 on the morning of 10 June 1918, the battleship Szent István—in the company of SMS Tegetthoff and seven other ships en route to attack the Otranto Barrage – was seen by chance and then hit by two torpedoes launched from the Italian MAS-15 Motor Torpedo Boat under Corvette Captain Luigi Rizzo near Premuda island, near Zara. Many of the 1,087 crew were asleep, getting rested for the battle expected in a few hours. Immediate chaos soon changed into frantic efforts to save the vessel which was rapidly shipping water. SMS Tegetthoff was hit by another torpedo from a second MAS, but it did not explode. Then Tegetthoff—which had at first sped away from the vicinity of the torpedo attack—returned and took Szent István in tow, in an attempt to reach the massive dry dock at Pula. However, the pumps were unequal to the task before them due to loss of steam pressure and the ship continued to slowly list, sinking at 06:12, almost 3 hours after being hit. It is debated that faults in the design – relatively low displacement and high centre of gravity, together with the weight of twelve main artillery – did not assist matters. However, most other battleships in The Great War which were either torpedoed or mined sank far more rapidly. There were, however, only 89 dead, partly attributed to the fact that all sailors with the K.u.K. had to learn to swim before entering active service. The attack on the Otranto Barrage was cancelled as a consequence of this attack. On 20 September, the French submarine was torpedoed north west of Cape Rodoni by the Austro-Hungarian submarine and lost with all hands.
