So I've been reading "Street without Joy" very aptly named. From start to finish it was pretty much one catastrophe after another for the French it's only surprising they held on as long as they did and certainly gives plenty of scope for ideas for dioramas !
A fiction book about Indochina I remember reading forty odd years ago was "The Devils Guard" was a very good read I recall.
Been looking at some of the vehicles used by the French during that time period there and I was surprised to see a photo of a Bren Gun carrier parked up alongside a Sdkfz 251 and in another French troops armed with MP 40's
Another interesting vehicle and perhaps one that TG might be interested in producing is the C15TA, used in North West Europe and Far East in WW2 by Britain and Commonwealth Countries, French in IndoChina and up into the mid sixties by ARVN.
