The cat’s original name is unknown. The name “Oscar” was given by the crew of the British destroyer HMS Cossack that rescued him from the sea following the sinking of the German battleship Bismarck. “Oscar” was derived from the International Code of Signals for the letter ‘O’, which is code for “Man Overboard” (the German spelling, “Oskar”, was sometimes used since he was a German cat).
The black and white patched cat was supposedly owned by an unknown crewman of the German battleship Bismarck and was on board the ship on 18 May 1941 when she set sail on Operation Rheinübung (German for Rhine Exercise), Bismarck’s only mission. Bismarck was sunk after a fierce sea-battle on 27 May, from which only 115 from her crew of over 2,100 survived. Hours later, Oscar was found floating on a board and picked from the water by the British destroyer HMS Cossack. Unaware of what his name had been on Bismarck, the crew of Cossack named their new mascot “Oscar”.
The cat served on board Cossack for the next few months as the ship carried out convoy escort duties in the Mediterranean Sea and North Atlantic Ocean. On 24 October 1941, Cossack was escorting a convoy from Gibraltar to Great Britain when she was severely damaged by a torpedo fired by the German submarine U-563. The crew were transferred to the destroyer HMS Legion, and an attempt was made to tow the badly listing Cossack back to Gibraltar. However, worsening weather conditions meant the task became impossible and had to be abandoned. On 27 October, a day after the tow was slipped, Cossack sank to the west of Gibraltar. The initial explosion had blown off one-third of the forward section of the ship, killing 159 of the crew, but Oscar survived this too and was brought to the shore establishment in Gibraltar.
Now nicknamed “Unsinkable Sam”, the cat was soon transferred to the aircraft carrier HMS Ark Royal, which coincidentally had been instrumental in the destruction of Bismarck (along with Cossack). However, Sam was to find no more luck there, and when returning from Malta on 14 November 1941 this ship too was torpedoed, this time by U-81. Attempts were also made to tow Ark Royal to Gibraltar, but the unstoppable inflow of water made the task futile. The carrier rolled over and sank 30 miles from Gibraltar. The slow rate at which the ship sank meant that all but one of the crew could be saved. The survivors, including Sam, who had been found clinging to a floating plank by a Motor Launch and described as “angry but quite unharmed”, were transferred to HMS Lightning and the same HMS Legion which had rescued the crew of Cossack. Legion would itself be sunk in 1942, and Lightning in 1943.
The loss of Ark Royal proved the end of Sam’s shipborne career. He was transferred first to the offices of the Governor of Gibraltar and then sent back to the United Kingdom, where he saw out the remainder of the war living in a seaman’s home in Belfast called the “Home for Sailors”. Sam died in 1955. A pastel portrait of Sam (titled Oscar, the Bismarck’s Cat) by the artist Georgina Shaw-Baker is in the possession of the National Maritime Museum in Greenwich.
He was then repatriated to the United Kingdom where he received room and board in the House for Sailors in Belfast. Happy to live far from the sea for the rest of his life, this was his home until his death (of natural causes) in 1955. During his lifetime, Unsinkable Sam became famous
