Transcript of Untitled Prezi

Submarine Warfare in WWII Hitler's Attack After the attack on Pearl Harbor, Hitler ordered submarine raids against American ships along the east coast. The Germans' aim in the Battle of the Atlantic was to prevent food as well as war materials from reaching Great Britain and the Soviet Union. Nazis could detect American ships easily because city lights formed silhouettes around the ships. Nazi Submarine Impact Unprotected American ships proved to be easy targets for the German submarines. In the first four months of 1942, the Nazis' submarines sank 87 ships off the Atlantic shore. Seven months into the year, German submarines destroyed a total of 681 allied ships in the Atlantic. America's and Allies' Response Allies responded to the submarine attacks by forming convoys with their cargo ships. Convoys were groups of ships traveling together for mutual protection from an enemy, this strategy was also used in World War I. The convoys were escorted across the Atlantic by destroyers equipped with sonar for detecting submarines under water. With improved tracking, the military was able to destroy German subs faster than the Germans could produce them. Cities also helped by dimming their lights at night to reduce depth of the ships' silhouettes. By winter 1943 soldiers began to see victories on land as well as sea.
