A second attempt to force the blockade took place in June 1918 under the command of Rear-Admiral Horthy. A surprise attack was planned, but the mission was doomed when the fleet was by chance spotted by an Italian MAS boat patrol, commanded by Luigi Rizzo that had already sunk, at anchor, the 25 year-old battleship (5,785 tons) the year before. Rizzo's MAS boat launched two torpedoes, hitting one of the four Austrian dreadnoughts, the which had already slowed down due to engine problems. The element of surprise lost, Horthy broke off his attack. Huge efforts were made by the crew to save "Szent István", which had been hit below the water-line, and the dreadnought battleship "Tegetthoff" took her in tow until a tug arrived. However just after 6 a.m., the pumps being unequal to the task, the ship, now listing badly, had to be abandoned. "Szent István" sank soon afterwards, taking 89 crewmen with her. The event was filmed from a sister ship.
