The French battleship Bouvet, in the Dardanelles. It was assigned to escort troop convoys through the Mediterranean at the start of the war. In early 1915, part of a larger group of combined British and French ships sent to clear Turkish defenses of the Dardanelles, Bouvet was hit by at least eight Turkish shells, then struck a mine, which caused so much damage, the ship sank within a few minutes. While a few men survived the sinking and were rescued, nearly 650 went down with the ship.
