auxiliary information: HMS Prince of Wales was a King George V-class battleship of the Royal Navy, built at the Cammell Laird shipyard in Birkenhead, England. She was involved in several key actions of the Second World War, including the battle of Denmark Strait against the German battleship Bismarck, operations escorting convoys in the Mediterranean, and her final action and sinking in the Pacific in 1941. Prince of Wales first encountered the Germans while being outfitted in her drydock, being attacked and damaged by German aircraft. She was heavily involved in the first contact with the German battleship Bismarck and the cruiser Prinz Eugen, and landed 3 hits on Bismarck including two critical hits, one which caused extensive flooding forward, and another which exploded under Bismarck's armour belt causing machinery damage, the combined effect of both hits caused her to make the ill-fated decision to return to port. Prince of Wales suffered heavy damage during the engagement and had to return to Rosyth to be repaired. Prince of Wales transported Prime Minister Winston Churchill to the Newfoundland Conference with US President Franklin D. Roosevelt.
