Two Infantry divisions and the artillery division are now in base areasnorthwest of the Delta. Twoinfantry divisions have arrived in base areas southwest of tlie Delta. Into the above forces, up toattalions have been assembling In the Thai Nguyen region, ostensibly for reorganization andtraining.

Since the fall of Dlcn Hlen Phu there has been noticeable decline in the morale of French Union forces. Recently, onemilitia battalion deserted, oneregular Army Group Mobile refused orders to go Into action. Vietnamese resistance to conscription lias increased and further Vietnamese defections within the nextays may be expected. On the other hand. French and Vietnamese troops have been engaged in local actions with no Indicationeriously impaired will to fight. If there areViet Minh victories or the Vietnameseconvinced that the French arethe capiUil, Hanoi, and substantial parts of the Delta, we believe Increased and serious defections would occur among Vietnamese units. In these circumstances, however, the French Expeditionary Corps and someunits would continue to fight.
Although there is no positive indications of Vict Minh intentions with respect to the Delta, throughout the period of this estimate the Viet Minh will be capable ofajor assault against the Red River Delta. The Viet Minh may soon undertake such an assault on the Delta because of the political advantages to be gained at Geneva by such action, or because they have becomethat French Union forces have become demoralized and that Vict Minh capabilities for assault combined with those of sabotage, terrorism, and uprisings would prove decisive in the Delta, except lor limited beachheads in the Haiphong area. Tlie Viet Minh will also believe that the French will be handicapped by lack of Initiative and the necessity of tying down considerable numbers for thistype defense. The Viet Minh will weigh these considerations against the obstaclesby terrain and weather and against the fact that the French Union forces willtheir maximum strength within the perimeter during this same period and will be superior in numbers, firepower, air strength, and logistic support.
We estimate that the most likely Viet Minh course of action will be to increase theirlevel of operations during the nextays and to continue attacks on French Union strong points, especially in the Delta. It is possible that elements of the Viet Minh battle corps, redeployed from Dien Bien Phu, will be committed in the Delta during this period to Increase the weight of Viet Minh attacks. The Viet Minh objectives will be to reduce the area under French control, to demoralize the Vietnam Army and militia, and reduce the capacity of the LOC between Hanoi andto such an extent thai the French position In Hanoi becomes untenable.we consider it likely that French Union forces will suffer some reverses, they will probably be able to retain possession of their key strong points and prevent theseverance of the LOC between Hanoi and Haiphong.
If,esult of tlie foregoing course of action, the Viet Minh should develop an
portunity loajor attack, the French Union forces have tlie militaryto hold Hanoi during the period of this estimate. However, If the Viet Minh achieve military successes In the Delta and French control of the native elements in critical areas of the Tonkin Delta deteriorates, the French may withdraw toward the HaiphongMoreover, even in advance ofmilitary pressure by the Vict Minh,for the integrity of the French Expcndi-tionary Corps and for the security of the loyal population in Hanoi might induce the French to evacuate Hanoi and withdraw toward the Haiphongajor attack would probably be accompanied by uprisings,and terrorist activities which wouldcertainly multiply and aggravate the diflleulties of the French. In any event, the French could almost certainly hold Haiphong during the period of this estimate. The French position at Haiphong will beby the arrival of two cruisers now en route.
