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 Corporal John Chyko (ASN: 1782520), United States Army, for extraordinary heroism in action while serving with Company E, 314th Infantry Regiment, 79th Division, American Expeditionary Forces, near Moirey, France, 10 November 1918. Taking command of a platoon in the absence of officers and sergeants, Corporal Chyko led a successful assault. With a small detachment of his men, he wiped out several machine-gun nests, thereby aiding in the advance of his battalion. On the same evening, after establishing listening posts, he patrolled with three men 1 kilometer from the front line, thus establishing security of the battalion position for the night.
