Three boats found the convoy and attacked, while a fourth failed to make contact. The fifth, U-42, met a freighter sailing independently; she attacked, but was counter-attacked by two destroyers that came to the scene and was destroyed. The attack on KJF 3 was an ad hoc affair (Blair describes it as "an uncoordinated free for all"[1]); though four ships were sunk, one of the attacking boats, U-45 was destroyed by the convoy escorts.
