The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to First Sergeant Walter Jamieson, United States Army, for extraordinary heroism on 30 July 1864, while serving with Company B, 139th New York Infantry. First Sergeant Jamieson voluntarily went between the lines under a heavy fire at Petersburg, Virginia, to the assistance of a wounded and helpless officer, whom he carried within the Union lines. At Fort Harrison, Virginia, 29 September 1864, he seized the regimental color, the Color Bearer and guard having been shot down, and, rushing forward, planted it upon the fort in full view of the entire brigade.
