Suffering from illness, Sgt. Seibert remained with his platoon and led his men with the highest courage and leadership under heavy shell and machinegun fire. With 2 other soldiers he charged a machinegun emplacement in advance of their company, he himself killing one of the enemy with a shotgun and capturing 2 others. In this encounter he was wounded, but he nevertheless continued in action, and when a withdrawal was ordered he returned with the last unit, assisting a wounded comrade. Later in the evening he volunteered and carried in wounded until he fainted from exhaustion.
