Although it is documented that ex-SS soldiers both joined the French Foreign Legion and fought in the French Indochina War until approximately 1947 when France began to crack down, the book's claim that a battalion-sized unit was composed solely of Germans is unsupported by evidence presented by many Legion historians, records and books (such as Bernard Fall's "Hell in a Very Small Place" and "Street Without Joy") on the French Indochina War. Skeptics have stated that the "Nazis in Indochina" myth came from communist bloc sources during the war.
