The President of the United States of America takes pleasure in presenting the Silver Star to Major James Patrick McWilliams, Jr. (MCSN: 0-73146), United States Marine Corps, for conspicuous gallantry and intrepidity in action while serving as Operations Officer of the First Battalion, Ninth Marines, THIRD Marine Division, in connection with operations against the enemy in the Republic of Vietnam. On 18 March 1969, after having completed Operation DEWEY CANYON the First Battalion was located at a landing zone near Tam Bui in Quang Tri Province, and had occupied the site for eight days while awaiting weather favorable for its helicopter extraction. During this time it was under constant harassment from scattered North Vietnamese Army units. In the early morning hours, the Marines came under a vicious hostile ground attack supported by mortars, and Major McWilliams, disregarding his own safety, immediately initiated an energetic defense of the position. In a dynamic display of courage and composure under fire, he directed the operations of the battalion mortar section, maintained communication with his infantry units, and coordinated strikes of fixed wing aircraft on the enemy force. When the intensive Marine attack caused the North Vietnamese to withdraw, he developed further suppressive fire to enable the effective protection of his Marines, should extraction become feasible. A short break in the weather finally permitted extraction helicopters to approach the landing zone and the enemy, noting this, then targeted the Marine aircraft with heavy fire. Repeatedly exposing himself to the intense fire, Major McWilliams directed the extraction of his men and, as the ground forces withdrew he coordinated increased supporting fire. His courage and timely actions inspired all who observed him and were a contributing factor to the North Vietnamese Army’s loss of forty-two soldiers killed with only minimal casualties. By his courage and devotion to duty in the face of grave personal danger, Major McWilliams contributed significantly to the completion of the operation and upheld the highest traditions of the Marine Corps and of the United States Naval Service.
