The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to First Lieutenant (Infantry) Ross Hamilton Calvert, Jr., United States Army, for gallantry in action while serving with Company I, 3d Battalion, 30th Infantry Regiment, 3d Infantry Division, in action against the enemy at Anzio, Italy, on 17 March 1944. While occupying a house to effect relief of another Infantry company the early morning of 17 March 1944, Lieutenant Calvert, two other officers, and their party came under heavy tank fire. As this fire lifted, the house was three times attacked by an enemy platoon reinforced by machine gun and mortars. Twice the attackers were repulsed; the third time the enemy gained positions behind a corner of the houses and behind an out building and began throwing many grenades. Lieutenant Calvert jumped from a window to the ground, crawled around the house to within 10 yards of the enemy, and with grenades and carbine fire forced the Germans to withdraw, killing three and wounding more. His gallant actions and dedicated devotion to duty, without regard for his own life, were in keeping with the highest traditions of military service and reflect great credit upon himself and the United States Army.
