World War II Congressional Medal of Honor Recipient. He served as a Private First Class, United States Army, Company H, 502d Parachute Infantry, 101st Airborne Division. He was awarded his medal for service at Best, Holland, on September 18, 1944. His citation reads "He distinguished himself by conspicuous gallantry above and beyond the call of duty. On 18 September 1944, in the vicinity of Best, Holland, his platoon, attempting to seize the bridge across the Wilhelmina Canal, was surrounded and isolated by an enemy force greatly superior in personnel and firepower. Acting as lead scout, Pfc. Mann boldly crept to within rocket-launcher range of an enemy artillery position and, in the face of heavy enemy fire, destroyed an 88mm. gun and an ammunition dump. Completely disregarding the great danger involved, he remained in his exposed position, and, with his M-1 rifle, killed the enemy one by one until he was wounded 4 times. Taken to a covered position, he insisted on returning to a forward position to stand guard during the night. On the following morning the enemy launched a concerted attack and advanced to within a few yards of the position, throwing hand grenades as they approached. One of these landed within a few feet of Pfc. Mann. Unable to raise his arms, which were bandaged to his body, he yelled "grenade" and threw his body over the grenade, and as it exploded, died. His outstanding gallantry above and beyond the call of duty and his magnificent conduct were an everlasting inspiration to his comrades for whom he gave his life." The 101st Airborne Division named " The Mann Theater", in his honor located at Fort Campbell, Ky.
