The Group ceased Carpetbagger missions on 16 September 1944 to haul gasoline to advancing mechanized forces in France and Belgium, along with attacking airfields, oil refineries, seaports, and other targets in France, the Low Countries, and Germany until February 1945. In October three of the 492d's squadrons, the 857th, 858th, and 859th, transitioned to night bombing operations. This proved to be a difficult transition, since the aircraft had been modified by the removal of the original bomb shackles and the oxygen systems. By mid-November, Headquarters, Eighth Air Force decided that the Carpetbagger aircraft just were not suitable and finally allocated oxygen-equipped B-24s for the new mission. The night bombing force of the 492nd became known as the "Black Liberators."
