(non-commissioned officer) assisted an Officer to capture a minnenwerfer and its crew of 20 men he continually sniped at the enemy snipers and was instrumental in keeping down our casualties. He inspired the men of his platoon to carry on by his coolness and courage under trying circumstances on his own initiative he connected the right flank of the Company with the right Battn and in order to do this he was compelled to cross open ground much exposed to enemy rifle and machine gun fire. He kept up communication in daylight with his platoon in the rear and his work throughout the whole operation was the highest quality.”
