# Convoy battles of World War II

Convoy Battles of World War II occurred when convoys of warships protected cargo ships assembled for mutual defense and were attacked by submarines, surface ships and/or aircraft. Most were in the North Atlantic from 1939 to 1943 and involved attacks by U-boat wolfpacks. Convoy battles also occurred in the Arctic Ocean, Mediterranean Sea and western Pacific Ocean.
