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 Private Joseph J. Dunn (ASN: 1245747), United States Army, for extraordinary heroism in action while serving with Company K, 111th Infantry Regiment, 28th Division, American Expeditionary Forces, in the Argonne Forest, France, 26 September 1918. Having become separated from his combat group, Private Dunn was making his way back to his lines when he came upon a machine-gun crew of four of the enemy. Rushing them with his pistol and hand grenades, he demanded and accomplished their surrender. He returned with the captured men and gun.
