The 458th Bomb Group (H) entered combat with the 8th Air Force early in 1944. Based at Horsham St. Faith in England, the combat crews participated in the decisive Campaigns Big Week, Big B, D-Day and the assault on Germanys oil industry waged by the USAAF up to VE-Day. The group also tested the operational use of Azon radio-controlled bombs. The 458th flew a total of 240 missions, during which over 13,000 tons of ordnance was dropped, and was achieved at the cost of sixty-five crews MIA or involved in operational accidents. This is their complete history.
