For most conspicuous bravery and initiative. During an attack the advance was held up in a portion of a village by two enemy machine guns, which were entrenched and strongly covered by wire entanglements. Cpl. Foster, who was in charge of two Lewis guns, succeeded in entering the trench and engaged the enemy guns. One of the Lewis guns was lost, but Cpl. Foster, with reckless courage, rushed forward and bombed the enemy, thereby recovering the gun.Then getting his two guns into action, he killed the enemy gun team and captured their guns, thereby enabling · the advance to continue successfully".
