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 William Rosio (ASN: 555288), United States Army, for extraordinary heroism in action while serving with Company A, 9th Machine-Gun Battalion, 3d Division, American Expeditionary Forces, near Mezy, France, 15 July 1918. Corporal Rosio commanded one of the two machine guns at the railroad bridge. He exposed himself to heavy machine-gun and artillery fire in order to effectively direct the fire of his guns against the enemy infantry crossing the Marne River. This was done with such effectiveness that many of the enemy boats were sunk and assault halted at the Marne River bank. Later, after his gun was disabled, he made a reconnaissance of the enemy lines and returned with valuable information.
