1917 – 1918
The outbreak of World War I in 1914 saw cutters become responsible for enforcing U.S. neutrality laws. With the declaration of war against Germany on 6 April 1917, a coded dispatch was transmitted from Washington to every cutter and shore station of the Coast Guard. Officers and enlisted men, vessels and units, were transferred to the operational control of the Navy Department. The Navy was augmented by 223 commissioned officers, approximately 4,500 enlisted men, 47 vessels of all types, and 279 stations scattered along the entire United States coastline.
