From American fighters in the Foreign legion, 1914-1918 by Paul Ayres Rockwell:
Schuyler Deming was fatally wounded during the German bombardment. It was his first day in the trenches, and a huge torpedo hurled over by an enemy trench-mortar exploded near him; his left leg was torn off* just below the knee, and bits of splinter lodged in his stomach. Deming was hastened to a field hospital, and died there on June 22. He was born at Columbus, Ohio, on March 24, 1884.
