The 387th Bomb Group moved to RAF Stoney Cross in Hampshire on 21 July 1944 when Ninth Air Force moved the 98th Bomb Wing's four Marauder groups into the New Forest area at the earliest opportunity to place them closer to the French Normandy Invasion beaches. On 27 June the 387th became operational from Stoney Cross, bombing along the invasion coast and supporting ground forces by raiding railways, bridges, road junctions, defended areas, and fuel dumps.
