Meetings at Pless Castle and on Pennsylvania Avenue

Show Summary Details


At a meeting at Pless Castle in Silesia, the German high command decided to adopt a policy of unrestricted submarine warfare, to go into effect February 1, 1917. The reasons for the decision are explored. Germany knew that this decision would be likely to involve the United States and other neutrals in war, but they decided that the policy could starve Britain into surrender before any effective US participation would affect the war. In the United States, Wilson announced that he would break diplomatic relations with Germany (as he had threatened to do on violation of the Sussex Pledge), but that the United States would await an “overt act of war” before taking stronger action.
