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 Staff Sergeant Olof L. Rosenlof (ASN: 39826992), United States Army, for gallantry in action while serving with the 35th Infantry Division, in action in the vicinity of ****, France, on 8 December 1944. Sergeant Rosenlof, attached to Company E, *** Infantry Regiment, served as Artillery Forward Observer from 6 to 8 December 1944. On the morning of 8 December, an advance group gained the far bank of the **** River but encountered strong enemy resistance and made little progress from that point, since the enemy was determined to reduce the American Bridgehead. Sergeant Rosenlof, exposing himself to enemy fire in order to better his observation of enemy targets, adjusted artillery fire so accurately, that its concentration scattered the enemy force and left the bridgehead intact. The enemy then instituted another counterattack supported by eleven tanks varying in size from the Mark IV to the Tiger Royal. Sergeant Rosenlof immediately acted to meet this new threat. Again exposing himself to the heavy enemy fire, he adjusted artillery fire of such accuracy as to make its effect devastating upon the enemy armor and force its withdrawal. Shortly thereafter, Sergeant Rosenlof was killed by enemy artillery fire. His gallant actions in exposing himself to the enemy fire in order to ensure the success of the battalion mission, are in accord with the military traditions of the United States.
