why did germany rescind the sussex pledge
The Sussex Pledge was a promise made in 1916 during World War I by Germany to the United States prior to the latter's entry into the war.Early in 1915, Germany had instituted a policy of unrestricted submarine warfare, allowing armed merchant ships, but not passenger ships, to be torpedoed without warning.n 1917, Germany became convinced they could defeat the Allied Forces by instituting unrestricted submarine warfare before the United States could enter the war. The Sussex pledge was therefore rescinded in January 1917, thereby initiating the decisive stage of the so-called First Battle of the Atlantic.
