On the night of 29/30 July 1943 an engineer mine clearance party was detailed to work with the Royal 22e Regiment during their attack on a feature south of Catenanuova. The engineer party and its protective infantry detachment became separated from their commander. Sapper O'Reilly, showing great initiative, too command of both the engineer party and the infantry covering party and reorganized them for their task. Under extremely heavy enemy fire he led this party forward, clearing mines from the route. His gallant action initiative and coolness at a critical stage allowed the infantry to successfully reach their objective.
