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) Harry Mase Keiser, United States Army, for extraordinary heroism in action while serving with Company H, 125th Infantry Regiment, 32d Division, American Expeditionary Forces, near Cierges, northeast of Chateau-Thierry, France, 31 July 1918. In the action to force the passage of the Ourcq River and capture the heights beyond, he distinguished himself by his conduct and personal example to his men. Under artillery fire and heavy machine-gun fire he continued to direct his platoon, even though severely wounded, in an effective manner against the enemy, until he was killed by machine-gun fire.
