Seeing that the left flank of his company was held up, he located the enemy machine-gun emplacement, which had been causing heavy casualties. In the face of heavy fire he rushed it singlehandedly, killing the entire crew with grenades. Continuing along the enemy trench in advance of the company, he reached another emplacement, which he also charged, silencing the gun with grenades. A third machine-gun emplacement opened up on him from the left and with similar skill and bravery he destroyed this also. Later, in company with another sergeant, he attacked a fourth machine-gun nest, being killed as he reached the parapet of the emplacement. His courageous action in destroying in turn four enemy machine-gun nests prevented many casualties among his company and very materially aided in achieving the objective.
