Institute, were kind enough to talk with me about their personal reminis-
cences. At the Institute of History, Do Quang Hung, Ngo Phuong Ba, Van
Tao, and Tran Huu Dinh were all very helpful in giving their time to explore
key issues related to my research. In particular, I would like to single out Vu
Huy Phuc, who was invariably pleasant and helpful as my escort during my
visit in 1990.

In Moscow, Gennadi Maslov provided me with some intriguing insights
into the inner history of the Party and various aspects of Soviet-Vietnamese
relations. Oxana Novakova of the Institut Vostokovedenia granted me an
extended interview to discuss Soviet views on the history of the Vietnamese
Communist movement. Director Li Xian Heng of the Guangdong Revolu-
tionary Museum was helpful when I was seeking information on Ho Chi
Minh's activities in China in the 1920s. Georges Boudarel and Bui Tin have
shared with me their own written recollections of the war.

I would also like to express my continued gratitude to others whose
names are mentioned in the acknowledgments to the first edition. That, of
course, includes my wife, Yvonne, whose help and encouragement cannot
be adequately acknowledged in a few short words in this preface.
