When I went to the funeral, it was an extraordinary experience to walk into that chapel at Arlington, that red brick chapel right outside the gate to the cemetery at Fort Myer. It was like a class reunion. They buried him as a general officer, with the horse and the caisson and all the trappings. The chief pallbearer was William Westmoreland, who had been the commander-in-chief in Vietnam, and William Colby, who had been the CIA head at one point, was another pallbearer, and here are all these others. Edward Lansdale, who put the Diem regime in power in the 1950s for the Eisenhower regime. He was there. Richard Holbrooke, who had been a young foreign service officer in Vietnam and went on to become the youngest Assistant Secretary of State for the Far East. All these faces. I’m saying, “Hi.” It was extraordinary. I realized that only this man, Vann, could bring all these people together, because he was such a unique figure. So I decided if I write a book, a biography of John, I can reach out to the larger history of the war and to whom the Vietnamese are, et cetera, and I can bring them into the story, and that’s what set me off writing the book.
