By February 8, 1918, Sgt. Stockham was in France and heading for the trenches. Between that time and his death, he served in the Toulon sector, in the Aisne operation, and at Belleau Wood. During the last-named battle, Gunnery Sergeant Stockham displayed the "conspicuous gallantry and intrepidity above and beyond the call of duty" which later earned him the Medal of Honor by an Act of Congress.
