First Lieutenant Wilcox volunteered for a liaison and successfully accomplished it, displaying marked bravery. Passing through a heavy artillery and machine-gun barrage, he pushed through the enemy outpost line, routed one of the outposts, and succeeded in establishing liaison between two battalions at a critical moment.
