100 Lancasters of No 3 Group bombed the fuel-storage depot at Regensburg accurately. 1 Lancaster lost. This was the last raid in the current campaign against German oil targets which had been waged since June 1944. Much of Bomber Command's effort during this period, sometimes at considerable loss, had been devoted to these oil operations, which had helped not only the Allied ground forces on the Western Front but also those fighting in Italy and on the Eastern Front.
