William Kirk MacNulty (May 22, 1892 in Antrim, Pennsylvania – August 3, 1964) was a U. S. Marine. He was a U.S. Marine Corps second lieutenant during World War I and saw action at the Battle of the Argonne Forest. He served as a captain during the Second U.S. Nicaraguan Campaign (1926–1933). During the Second World War, as a lieutenant colonel he commanded the U.S. Marine Corps defense of Guam against Imperial Japanese forces during the First Battle of Guam. He was incarcerated by the Japanese as a prisoner of war. He was promoted to brigadier general during captivity and retired from military service in 1946. He is buried at the Golden Gate National Cemetery in San Bruno, San Mateo County, California.
World War I (U.S. 1917–18) As a second lieutenant, William K. MacNulty (MCSN: 0-587) was awarded the silver star for gallantry in action against an enemy of the United States while serving with the Sixth Regiment (Marines), Second Division, American Expeditionary Forces during the Meuse-Argonne Offensive (also known as the Battle of the Argonne Forest) September 30 to November 11, 1918.
Second U.S. Nicaraguan Campaign (1926–33) As a U.S. Marine Corps Captain, MacNulty was awarded the Navy Cross for heroic action in combat at the Battle of El Bramadero during the Second U.S. Nicaraguan Campaign.
Battle of Guam At the very outbreak of World War II, during the Battle of Guam on December 8, 9 and 10, 1941, then, Lt. Col. MacNulty's 153-man U.S. Marine barracks of a U.S. Armed Forces island garrison of 424, outfitted with only small arms and mounted .30 caliber machine guns, defended Guam against the successful attack of then Japanese Maj. Gen. Tomitarō Horii's 5,500 man ground force, supported by the Japanese Fourth Fleet's heavy cruiser Aoba, destroyers Yuzuki, Kihuzuki, Uzuki and Oboro, 12 naval transports, 4 gunboats, 5 subchasers, a minesweeper squadron and other auxiliaries, which under command of Japanese Adm. Shigeyoshi Inoue, prior, surrounded Guam, and, also, air forces from then Japanese Saipan. Guam was the first piece of American soil surrendered during the war. MacNulty's 153 Marines suffered 13 dead and 37 wounded (losses and other casualties of near one third their compliment) before ordered to surrender by a beleaguered U.S. Naval Captain and Guam Governor George Johnson McMillin, who was, then, himself, confronting 400 armed Japanese ground troops with defense of only an 80-man native Insular Force Guard. MacNulty's U.S. Marines, however, could take comfort that with the Japanese attack forces preparations, deployment and predominant withdrawal, the U.S. Marines' tiny, otherwise, insignificant, presence at Guam, because of a Japanese intelligence mistake, had tied down 6,000 first-class Japanese enemy combat troops, a cruiser and support ships and aircraft for well over a month.
Promotion as P.O.W. and, subsequent, retirement MacNulty was promoted to brigadier general in 1942. He retired from military service in 1946. He died in 1964 at the age of 72.
