Nung Battalions in Saigon 1955

Hi,

I saw on Page 283 in The Indochinese Experience of the French and Americans: Nationalis and Communism in Cambodia, Laos and Vietnam. [/u]by Arthur Dommon Indiana University Press 2002. A reference to three ex-Tonkin BVN composed of Nung being moved into Saigon on 3/1/55 in preparation for a battle with the Binh Xuyen. Does anyone have information on which three BVN these are?

Regards
