PETROL-CARRYING
70 Halifaxes of 4 Group started a series of flights to carry petrol in jerricans from England to airfields in Belgium, in order to alleviate the severe fuel shortage being experienced by Allied ground forces. 4 Group would fly 435 such sorties during an 8-day period. Each Halifax carried about 165 jerricans, approximately 750 gallons of petrol, on each flight. The total amount of petrol lifted during the period was approximately 325,000 gallons, about the same amount of fuel that the Halifaxes themselves consumed. No aircraft were lost during these operations.
Minor Operations: 4 R.C.M. sorties, 5 Hudsons on Resistance operations. No losses.
