Sergeant William Shemin distinguished himself by extraordinary acts of heroism at the risk of his life above and beyond the call of duty while serving as a Rifleman with G Company, 2d Battalion, 47th Infantry Regiment, 4th Division, American Expeditionary Forces, in connection with combat operations against an armed enemy on the Vesle River, near Bazoches, France from August 7 to August 9, 1918. Sergeant Shemin, upon three different occasions, left cover and crossed an open space of 150 yards, repeatedly exposing himself to heavy machine-gun and rifle fire, to rescue wounded. After officers and senior noncommissioned officers had become casualties, Sergeant Shemin took command of the platoon and displayed great initiative under fire until wounded on August 9. Sergeant Shemin's extraordinary heroism and selflessness, above and beyond the call of duty, are in keeping with the highest traditions of the military service and reflect great credit upon himself, with G Company, 2d Battalion, 47th Infantry Regiment, 4th Division, American Expeditionary Forces, and the United States Army.
