Heavy bombers of the USAAF 15th Air Force attacked refineries at Ruhland, where fuel production ceased completely after the attack.
The 388th received another DUC for three outstanding missions: an attack against a tire and rubber factory in Hanover on 26 July 1943; the bombardment of a synthetic oil refinery in Brux on 12 May 1944; and a strike against a synthetic oil refinery at Ruhland on 21 June 1944, during a shuttle raid from England to the Soviet Union.
