First, I would recommend two books by Bernard B Fall, a French war correspondent and historian. They are peerless historical accountings of the First Indochina War, and are essential to understanding the American debacle in Vietnam. His analysis of the failings of the French were a direct warning to the US, which were largely ignored, resulting in a predictable failure. He died in 1967 while embedded with US Marines in Vietnam after stepping on a mine.

• Street Without Joy starts with post WW2 French colonial Indochina and the rise of the Indochina War in 1946, giving detailed analysis and reporting on the conflict until it ended in 1954 following the battle of Dien Bien Phu.
  
• Hell In A Very Small Place covers specifically the battle of Dien Bien Phu, how the Viet Mihm were able to prevail and how it could happen to the US.
  
  
  I also recommend a book by Romeo Dallaire, a Canadian general.
  
  
• Shake Hands With The Devil covers Dallaire's experiences as the commanding officer of the failed UN peacekeeping mission in Rwanda that culminated with the genocides in '94.
