CONSEQUENCES WITHIN INDOCHINA OF THE FALL OF DIEN BIEN PHU
THE PROBLEM
To estimate the probable consequences within Indochina during the next two or three months of the fall of Dien Bien Phu within the near future.
SCOPE
The consequences of the fall of Dien Bien Phu on the political situation in France, and the repercussions of major decisions in France or Geneva on the situation in Indochina, are excluded from the scope of this estimate.
CONCLUSIONS
1. The fall of Dien Bien Phu would have far-reaching and adverse repercussions, but it would not signal the immediate collapse of the French Union political and military situation in Indochina. As a con sequence of the fall of Dien Bien Phu, the morale of French Union forces would receive a severe blow. A crucial factor in the military situation thereafter would be the reliability of native units, particularly the Vietnamese. There would almost certainly be increased desertions, and the possibility cannot be excluded that the native components of French Union forces might disintegrate. However, we believe that such disintegration would be unlikely during the ensuring two or three months, and that for at least this period the major part of the native troops would probably remain loyal.
2. Assuming no such disintegration, the fall of Dien Bien Phu would not in itself substantially alter the relative military capabilities of French Union and Viet Minh forces in Indochina during the next two or three months. The French stand at Dien Bien Phu has produced certain compensatory military results. It has prevented an overrunning of Laos and has resulted in the inflicting of casualties upon the Viet Minh comparable in number to the total French force committed at Dien Bien Phu. The bulk of Viet Minh forces released by the fall of Dien Bien Phu would probably not be able to move, regroup, and re-equip in time to be employed in new major operations during the next two or three months, although some lightly equipped infantry battalions might be made available more rapidly for operations in the Delta region.
