When the battalion was going through Gihissignies in support of the attack, information was received that the left company of the leading battalion had been held up. Under heavy shell fire he went forward to reconnoitre, and found that the supporting battalion appeared likely to become prematurely involved in the fighting. By his energy and initiative in taking command of the situation this was prevented."[2]
