1918 06 10 MAS torpedo boats sink the Szent István battleship
Two Italian MAS, a type of motor torpedo boat employed by the Regia Marina, discovered Szent István and her half-sister Tegetthoff early in the morning of 10 June 1918 while returning after a night patrol off the Dalmatian
coast. They penetrated past her escorts and torpedoed her twice abreast
her boiler rooms. They flooded, which knocked out power to the pumps,
and Szent István capsized less than three hours after being torpedoed. All but 89 of her crew were rescued.
