Meet the sailor who served with the Axis and the Allies and survived three sinking ships

Nicknamed "Unsinkable Sam," this German sailor served with the Nazi Kriegsmarine and the British Royal Navy during world War II. Three of the ships on which he served were sunk and he miraculously survived all three.

His first cruise was on the legendary German dreadnaught battleship Bismarck. He boarded with his best friend in 1941 as it departed Germany to wreak havoc on British shipping in the Northern Atlantic. Bismarck was sunk after a fight against an aircraft carrier, three battleships, three cruisers, and six destroyers. Only 118 of the ship's 2,200 survived. Oscar (the real name of "Unsinkable Sam") was found floating on a board by the HMS Cossack, and was put to work immediately by the British crew.

After serving on the Cossack for months, Oscar was accepted by the ship's crew. One day on escort duty near Gibraltar, Cossack was torpedoed by a German U-boat and was heavily damaged. Oscar survived. Although attempts were made to tow the ship back to port, the weather made it impossible and the ship was abandoned and sank near Gibraltar.

Now having earned his "Unsinkable" moniker, he was transferred to the aircraft carrier HMS Ark Royal, which was itself torpedoed off of the island of Malta in the Mediterranean, and sank thirty miles offshore. Only one member of the crew was lost because the ship sank at such a slow pace.

Sam survived, but his days at sea were over. He spent the rest of the war serving the governor of Gibraltar and would live for another decade after the war's end. He died in Belfast, Northern Ireland in 1955.
