4 maio 1916 ano - Sussex Pledge

Descrição:

The Sussex Pledge was a promise made by Germany to the United States in 1916 during WW1 before the United States entered 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.
