107 Lancasters and 12 Mosquitos of No 5 Group attacked the oil refinery in Tonsberg in Southern Norway in the last raid flown by heavy bombers. The attack was accurately carried out and the target was severely damaged. A Lancaster of No 463 Squadron came down in Sweden, the last of more than 3,300 Lancasters lost in the war; Flying Officer A Cox and his all-British crew all survived and were interned in Sweden until the end of the war - only a few days away.
