I wish I could recall where I read this stuff about Vann, but the gist of it wasn't very flattering---that he ignored warnings from the ARVNs on one occasion and had them drop right into a very hot zone that killed a lot of them. He denigrated them at the very moment that several ARVN chopper pilots were making runs to hold off the commies and get their guys out. It was a totally different portrait of Vann.
Your second sentence went to the lie that is the premise of this and other pieces by this author. John Paul Vann is buried in Arlinton National Cemetery with our other heroes as a Lieutenant Colonel. He was no Major General in equivalent rank, brevet rank or using monopoly rank. I knew Vann and he was a truthful man when dealing with me. He would be appalled that some tinhorn is trying to make a name and reputation by elevating his rank to one he despised.
Vann died as a civialian while in the pay of an American civilian agency. In no way did any Americans ever command anything Vietnamese in Vietnam.
Even on our Special Forces camp we flew the flag of South Vietnam. Their Special Forces, the Luc Long Dat Biet, were our counterparts and we were their advisors. That would have been the case if they ever left their compound. In their absence, we took care of things. But we did not run up the Stars and Stripes and call the camp an American installation or ourselves commanders of Vietnamese citizens. That entire notion belies why we were in Vietnam.
Given that Vietnam history is such a political minefield, can you gentlemen recommend any works to me? I grew up during the war, and turned 17 three or four months after the last American chopper lifted off from the roof of the U.S. Embassy in Saigon, which remains one of the enduring images of my life. And yet, I know almost nothing reliable about the war.
