6 Bomber Group October 12, 1944
96 Halifaxes from 408, 415, 420, 425,426, 427,429, and 432 squadrons were ordered to attack the oil plants at Wanne-Eickel. The crews were over the target at between 16,000 and 20,000 feet, releasing1,052,000 lbs of high explosives. The oil refinery and a chemical plant were seriously damaged. More than 50\%" of these aircraft were damaged by flak over this target. Richard Koval (6bombergroup.ca)
I11 Halifaxes and 26 Lancasters of 6 and 8 Groups attacked the oil plant. A direct hit 1111 n storage tank early in the raid produced dense cloud and smoke which hindered later bombing. A German report says that the refinery itself was not seriously damaged but that the GA VEG chemical factory was destroyed; it is possible that the bombers were aiming at the wrong target. The report also states that 24 buildings were hit in nearby housing areas and that 103 German civilians, 2 foreign workers 1 prisoner of war were killed, most of them being in makeshift 'earth shelters'.
