The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Silver Star to Staff Sergeant Hubert C. Grimes, United States Army, for gallantry in action while serving as Reconnaissance Platoon Sergeant, Division Trains, 6th Armored Division, in the vicinity of Avranches, France, on August 1, 1944. In the face of enemy strafing, Staff Sergeant Grimes placed himself in an exposed position and successfully directed the deployment of the Division Trains. At Plouvien, France, on 8 August, 1944, as reconnaissance non-commissioned officer he made vigorous mounted and dismounted reconnaissance against enemy sniper and machine gun fire, to deploy vulnerable gasoline and ammunition trains during an enemy counter-attack. His leadership and unhesitating courage have been a constant inspiration to his platoon.
