    April 6th, 2017, marked the 100th anniversary of the Coast Guard’s entry into World War I and the Service’s 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. These ships included two combat losses. On August 6th, 1918, U-140 sank the Diamond Shoals Lightship after her crew transmitted to shore the location of the marauding enemy submarine, but no lives were lost. However, on September 26th, 1918, after completing her convoy escort duty from Gibraltar to Milford Haven, England, Cutter Tampa was torpedoed by UB-91. The cutter sank killing all 131 persons on board, including four U.S. Navy men, sixteen Royal Navy personnel and 111 Coast Guard officers and men. It proved America’s greatest World War I naval loss of life due to combat.

    Nearly 9,000 Coast Guard men and women would participate in the war. This number included over 200 Coast Guard officers, many of whom served as warship commanders, troop ship captains, training camp commandants and naval air station commanders. In all, Coast Guard heroes received two Distinguished Service Medals, eight Gold Life-Saving Medals, almost a dozen foreign honors and nearly fifty Navy Cross Medals, dozens more than were awarded to Coast Guardsmen in World War II.

Charles Green enlisted as Frank Charles Garrett in the United States Coast Guard on 6 April 1917. Born in Kentucky and raised in Flip, Missouri, he changed his name to avoid being found by his father, who had quite a temper. Green served overseas in the European theater on TAMPA during World War I, and perished with all hands when TAMPA was torpedoed and sunk on 26 September 1918 off the coast of England. He was 22. Currently, his Purple Heart is being processed for awarding.

The U.S. Coast Guard has a unique role as a military armed force with extensive peacetime missions. In nearly every U.S. Conflict, the service has been a part of wartime naval operations. The most notable occurrences were during World War I and World War II, where the entire service integrated into the Department of the Navy. Beginning with World War I, this thesis traces the Coast Guard’s development and expansion throughout the interwar period up until World War II. It examines the hearings and proceedings of the General Board of the Navy to show how Coast Guard cutters were prepared for combat. It also analyzes strategic war planning documents to show the Navy’s intent to mobilize, organize and employ the Coast Guard during war. A Master's Thesis by LCDR Nolan V. Cain, USCG.
