The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Silver Star to Major William C. Chamberlin (MCSN: 0-5929), United States Marine Corps Reserve, for conspicuous gallantry and intrepidity as Executive Officer of the Second Battalion, Eighth Marines, SECOND Marine Division, in action against enemy Japanese forces on Tinian, Mariana Islands, 31 July 1944. At the height of an enemy counterattack, Major Chamberlin moved from company to company, coordinating their efforts and encouraging the men of the Battalion despite intense hostile fire. Under his personal direction, the Battalion launched local counterattacks against Japanese penetrations, and repulsed the enemy with heavy losses. His courage, leadership and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
