An interesting piece from a Google Books search, about the 131st US Infantry (First Infantry IL National Guard) during WWI:
PVT. PHILIP J. BOENING, Company M. On Oct. 10, 1918, on the east bank of the Meuse, due to intense shelling and terrific machine gun fire, it became necessary for two platoons to take up a position on the reverse slope of a hill. Observation of the enemy had to be maintained. Volunteers were called for.
Pvt. Boening, in company with Cpl. O’Keefe and Pvt. Hartman, volunteered, and under terrific fire established an observation post and kept up liaison with thoir platoon. They maintained the position until nightfall, when the platoons, under cover of darkness, were enabled to come up and dig in on the position.
The report notes Philip was stationed in France in Company M.
