Code breaking dnurig WWII truly turned the tide in both the Pacific & Atlantic. The Brits broke the German Enigma code which gave them a big advantage tracking the German Wolfpacks in the North Atlantic. It was vital that the convoys from the U.S. to Britian get thru with food, war material and manpower for England to survive, and breaking the Enigma code helped turn the tide. Until the German code was broken the U-boats were creating havoc on the convoys in their attempt to strangle England.
