British Admiral Sir Max Horton's ideas lead to success in Atlantic: Late in 1942, British admiral Sir Max Horton, commander-in-chief of the Western Approaches Command, changed antisubmarine strategy. He sent groups of fast "hunter-killer" ships away from their convoys to attack German U-boats, preventing the formation of "wolf packs." By spring 1943, those tactics had successfully reopened the North Atlantic to merchant and military shipping. As a WWI submarine commander, Horton had responded to an admiral's assessment of all submariners as "un-English" and "pirates" by flying the "Jolly Roger" (skull and crossbones flag) after his sub sank two German ships. WWII British and Australian submariners took up the Jolly Roger as a signal of success.
