As of today general history books and school history textbooks in the West criticize the French for completely believing it would be impossible for the VietMinh to bring artillery up the mountains of Dien Bien Phu and thus general Western history books make it out as the French were complete fools who were not following military doctrine . However if you read magazine articles and intelligence reports of various Western nations (ESP U.S. and Great Britain), they all stated that it would be impossible for the VietMinh to transport artillery up DBP!Infact Pentagon Papers created by American intelligence agencies all stated it would be completely impossible for the VietMinh to ever be able to transport artillery to DBP!British Secret Service intelligence papers state the same thing too!Its not just intelligence agencies of Western nations that believed it would be impossible for the VM to bring artillery in DBP. Military forces of every nation in the Western world all believed that the VM simply cannot bring artillery up to DBP!Literally the generals of every military forces of all Western nations including those of US,Britain, the Netherlands,Italy, Spain, and even the West Germany all believed it would be improssible for VietMinh to bring artillery! Even British and American generals who had been in DBP to observe the fortress before the battle all completely agreed that it there would be no way that the VietMinh to bring artillery up DBP! Believe or not,even the Joint Chiefs of Staff believed it would be impossible for the VM to possess artillery in the upcoming battle in DBP!The Joint Chiefs of Staff were so convinced that VietMinh simply cannot bring artillery in the battle that even President Eisenhower himself became completely convinced that any attack on DBP would fail because the VietMinh won't be able to use artillery!Even Churchill agreed with the intelligence reports! The only western generals who believe that the VietMinh will be able to bring artillery up DBP are a few dissident voices in the French army including General Renee Cogny(who was the one who sent paratroopers to attack and fortify DBP in the first place).Colonel Cogny and several other French officers doubted French intelligence reports of the impossibility of artillery being used by the VM in DBP and even tried to warn General Navarre(head of the French forces during DBP) and the entire French military of the possibility of VM being able to bring artillery in DBP.
As historians and history books today criticize the French for inaccurate intelligence in DBP, this leads me to one question:Why did all military forces of the West including top generals and political leaders of the West including Eisenhower and Churchill believed the VM could never bring artillery in DBP?Why did no one listen to the warnings of lower ranking French officers?I mean looking in retrospect,it s as though Western nations all see the VIetnamese as too primitive to transport artillery!
