In the wake of a German raid on Scapa Flow, the British Admiralty admitted that the Home Fleet base was vulnerable to air attacks. The fleet was ordered to depart Scapa Flow between 19 and 26 Mar. In anticipation of this move, German submarines U-57, U-19, U-21, and U-22 began to move toward Scapa Flow in an attempt to attack the departing warships.
