Military history readers might like Jules Roy's
The Battle of Dienbienphu about the beginning of the end of the French colonial empire in Indochina by the Vietminh forces of Nguyen Giap.
It's a better read than Bernard Fall's book:
"Hell in a Very Small Place", imo. Although that wasn't a bad book nor was his
"Street Without Joy". All these books are good background to our experience there.
