Not long afterwards, the "Kriegsmarine" launched Operation Rheinübung. The "Bismarck" and heavy cruiser "Prinz Eugen" set out into the Atlantic from Norway. Their target was the Atlantic Convoys. During the later stage of the "Bismarck" operation, a Catalina of No. 209 Squadron RAF spotted the vessel, just 650 miles short of his destination port of Brest, France. It relayed the message to the British Fleet, enabling Fairey Swordfish aircraft to intercept. An 818 Naval Air Squadron FAA aircraft piloted by Sub-Lieutenant John Moffat hit the "Bismarck" with a torpedo on its stern, jamming its rudder gears, which eventually led to its sinking. "Prinz Eugen" had been detached prior to "Bismarck" last battle. Despite her discovery by Coastal Command's aircraft further south, she escaped to Brest on 1 June. "Rheinübung" was the last attempt by a "Kriegsmarine" surface ship to break-out into the Atlantic.
