Becoming separated from the balance of his company because of a fog, Capt. Mallon, with 9 soldiers, pushed forward and attacked 9 active hostile machineguns, capturing all of them without the loss of a man. Continuing on through the woods, he led his men in attacking a battery of four 155-millimeter howitzers, which were in action, rushing the position and capturing the battery and its crew. In this encounter Capt. Mallon personally attacked 1 of the enemy with his fists. Later, when the party came upon 2 more machineguns, this officer sent men to the flanks while he rushed forward directly in the face of the fire and silenced the guns, being the first one of the party to reach the nest. The exceptional gallantry and determination displayed by Capt. Mallon resulted in the capture of 100 prisoners, 11 machineguns, four 155-millimeter howitzers and 1 antiaircraft gun.
