Effect of World War I on Mahanian Theory: • Support in two areas: • Commercial antagonism and rivalry cause war. • Faith in the battle fleet for command of the sea. • Unrestricted Submarine Warfare's implications ignored. • Commerce raiding can affect the course of the war. • Importance of convoy system to protect against submarine attacks.
