World War I

The Coast Guard’s played an important role in supporting the war effort. It was on Friday, April 6th, 1917, the day Congress declared war on Germany, that the U.S. Navy’s communications center in Arlington, Virginia, transmitted the code words “Plan One, Acknowledge” to Coast Guard cutters, units and bases initiating the Coast Guard’s transfer from the Treasury Department to the Navy and placing the Service on a wartime footing. During the war’s nearly nineteen months, the Coast Guard and Lighthouse Service would lose almost two hundred men and five ships. Nearly 9,000 Coast Guard men and women would participate in the war.
