The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pride in presenting the Silver Star (Posthumously) to Sergeant Rockwell Grant Jamison (ASN: US-56400982), United States Army, for gallantry in action while engaged in military operations against an armed hostile force in the Republic of Vietnam. On 12 July 1967, Sergeant Jamison distinguished himself while serving as a Squad Leader in Company B, 1st Battalion, 12th Infantry Regiment, 4th Infantry Division, operating south of Duc Co. Shortly after his platoon moved out of its patrol base, it began receiving heavy small arms and automatic weapons fire from a large North Vietnamese Army force. The platoon stopped and deployed in defensive positions. The area Sergeant Jamison’s squad occupied was open and exposed to the intense enemy fire. Realizing that his squad had to move to a safer position, Sergeant Jamison leapt to his feet and began firing directly at the enemy. His fearless action threw the enemy into confusion and allowed his squad to begin maneuvering. Shouting directions and encouragement to his men, Sergeant Jamison stayed back to cover their movement. He was so close to the enemy that often he did not have time to reload his rifle, but instead had to drive them off in hand-to-hand combat. As his men reached better positions, Sergeant Jamison began moving among them distributing ammunition and helping the wounded. Although the enemy unleashed mortar fire on his squad’s area, he continued to lead his men in their valiant efforts until he was mortally wounded. Sergeant Jamison’s gallantry is in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
