The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to First Lieutenant (Infantry) William H. Eyler, United States Army, for extraordinary heroism in action while serving with 166th Infantry Regiment, 42d Division, American Expeditionary Forces, northeast of Chateau-Thierry, France, 2 August 1918. Never faltering in his advance during the attack on the hill commanding Marcuil-en-Dole, and disregarding all personal danger, Lieutenant Eyler led his company forward through heavy fire until he was killed.
