What was the Battle of the Atlantic, and how did the Allies win it ?

The battle of the Atlantic was the naval warfare in the Atlantic Ocean between the German Kriegsmarine and the Allies' navies. The German Kriegsmarine had two categories: the Unterseefloat, which contained U-Boats (a type of German submarine), and the HochSeeFleet which contained the Capital ships, cruisers, and destroyers. The U-Boats were the main danger, as many Allied convoys had no escorts at the beginning of the war. The HochSeeFleet lost its pride, the Bismarck, on its maiden voyage, and never saw the success the Submarines did. Eventually, the battle of the Atlantic was won because of Germany's neglection of the navy, focusing all of it's resources to the land wars. Special sonar technology eventually made U-Boats much less scary, as they could be detected. :)
