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 (Field Artillery) John R. Grimes (ASN: 0-2025348), United States Army, for gallantry in action as a member of Battery A, 26th Anti-Aircraft Artillery (AW) Battalion, 24th Infantry Division, in action against the enemy near Taepyong-ni, Korea, on 16 July 1950. When an effective enemy road block had cut off the Division Artillery and elements of the 19th Infantry Regiment, Lieutenant Grimes brought his half track anti-aircraft vehicles into the area to combat the enemy. Under his direct supervision, his platoon, by the accuracy and volume of its fire, successfully destroyed three enemy machine guns and an anti-tank weapon. In addition, heavy casualties were inflicted upon the opposing enemy company, causing them to withdraw. Although wounded in the action, with complete disregard for his own safety, he continuously exposed himself while moving to each of his seven vehicles, assisting in the evacuation of the injured, and inspired his crews to greater efforts. Only when the enemy pressure on the friendly troops had been relieved did he permit himself to be evacuated for medical aid. His courage, unselfish devotion to duty, and superior leadership, enabled the friendly troops to withdraw with a minimum of casualties and loss of equipment. His gallant actions reflect the greatest credit upon himself and the United States Artillery.
