In the online book "Generally Speaking" by Richard Rohmer more details are disclosed on page 170-171.

It appears that his logbook was on a Dakota detailed for the move from Evreux to Diest, but somehow the aircraft was then ordered to fly to the UK instead. There the cargo was unloaded. After some days the or another Dakota had to go to Diest with the original load.
According Rohmer the pilot mistook Diest for another Diest (haven't found out yet what other Diest is referred to...) which brought the Dakota over enemy territory, with fatal results.

A loss over Holland therefore more likely?
