Shortly before approaching the target the bomber was swept by cannon and machine gun fire, which set fire to the rear turret and the port inner engine and also damaged the intercomm. The rear gunner was injured by splinters in the face and slightly burnt and the mid upper was hit in the leg by a machine gun bullet. The attack came from astern well down and as soon as the pilot saw the tracer he commenced a corkscrew port, losing height rapidly to gain extra speed, having a full load on. Both gunners saw a JU88 coming in from astern down, but rear gunner could not fire as guns had been damaged and mid upper could not get guns to bear. Enemy aircraft broke away down and attacked again from same position opening fire from approx 600 yards and closing into 100 yards. Enemy tracer all passed above bomber and he broke away to astern down and was not seen again. The pilot resumed course on 3 engines and bombed the target at very low altitude. Rear turret badly smashed. Port inner engine, mid upper turret and fuselage holed in many places.
