The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to First Lieutenant (Cavalry) William O. Coleman, United States Army, for extraordinary heroism in action while serving as Aid-de-Camp, 1st Infantry Brigade, 1st Division, American Expeditionary Forces, near Soissons, France, 20 July 1918. His liaison group having suffered many casualties, Lieutenant Coleman exposed himself to heavy fire on two different occasions in traversing the front line of the 18th Infantry during the attack. He returned each time with valuable information. Later, while on a mission to the front line, he was severely wounded, which necessitated the amputation of his left arm. Previously at Seicheprey, France, 1 March 1918, while on a mission to obtain identifications of enemy participants in a raid, he went out in advance of our lines, under heavy enemy fire, to assist in the capture of an enemy raider.
