The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Silver Star (Posthumously) to First Lieutenant (Infantry) William G. Buster (ASN: 0-400554), United States Army, for gallantry in action while serving with Company F, 143d Infantry Regiment, 36th Infantry Division. First Lieutenant Buster was in command of Company F, 143d Infantry which occupied a defensive position on Mt. Rotondo, Italy, on the morning of 16 November 1943. Although heavily concentrated enemy artillery fire was falling within his position, First Lieutenant Buster, without regard to his own life and in a manner which inspired confidence and courage of his men, boldly exposed himself to the enemy fire in exercising constant and direct supervision over the preparation and improving of his defensive position. Having occupied the position the previous night he worked continuously without rest. Learning that artillery fire had interrupted communications with the Company Observation Post, and realizing the importance and responsibility of his position, without waiting for the artillery concentration to life, he personally went forward to the observation post. Shortly after his arrival at the observation post an artillery shell struck nearby fatally wounding him. Serious and energetic in the performance of his duties, First Lieutenant Buster has succeeded in organizing his position effectively and efficiently. 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, his unit, and the United States Army.
