Leendert,
Very interesting. From the account of Ray Sherman who saw (or heard) the crash, he was located about 6 miles from St Cloud. He talks about walking to St Cloud from camp. Today St Cloud is called Gdyel. On Google maps there is also a "Foret des Lions" between Gdyel and Oran and also La Montagne des Lions.
I suspect that this the crash site.

Also a reference here to Lion Mountain as Djebel Khar.
I am thinking it is now quite possible Werfel was on the B-25, perhaps with some other non-321st BG passengers.

Possibly Werfel's IDPF file would hold the answers, but it would take almost a year to get it.
