"The rear gunner of the Lancaster (or other type of bomber-aircraft) acted first, and before the pilot of the Ju 88 could open fire his aircraft received a full burst from the Lancaster's tail armament. At the same moment the Ju 88 received another burst from below, presumably from a night fighter; the combination of both attacks put the flying controls out of action, in addition to which the port engine caught fire. The crew baled out and the four members were captured." (from

So maybe there is more to find out about this encounter in the RAF bomber-reports of that night in that region?
