Brest, France

The U.S. Navy established a Naval Operating Base, with the Frency Navy, at Brest, France, in June 1917 to engage German submarines.  The location became a landing point for U.S. Army troops for service with the American Expeditionary Forces.  In September 1919, both the Naval Port Office and the Army Transport Service were ordered closed, but the Naval Port Office continued operations until July 1920.
