Laurence, it is the only Wellington loss that I can find recorded in that geographical area. However, the details seem to indicate a loss on the airfield rather than in the bondou.
Interesting to note that the serial HG116 was allocated to an ASR version of the Warwick. Examples of this version were on the strength of 294 Sqn, alongside the Wellingtons, until early 1946 it seems. However, I can find no record of an accident involving that aircraft.
