While in Bergen, "Prinz Eugen" took on of fuel; "Bismarck" inexplicably failed to similarly refuel. At 19:30 on 21 May, "Prinz Eugen", "Bismarck", and the three escorting destroyers left port. By midnight, the force was in the open sea and headed toward the Arctic Ocean. At this time, Admiral Raeder finally informed Hitler of the operation, who reluctantly allowed it to continue as planned. The three escorting destroyers were detached at 04:14 on 22 May, while the force steamed off Trondheim. At around 12:00, Lütjens ordered his two ships to turn toward the Denmark Strait to attempt the breakout into the open waters of the Atlantic.
