It was the friendship between two war veterans from Vietnam and the US, Nguyen Van Nghia and Paul Reed. When Paul Reed was 17, he volunteered to join the US's army. He came to Vietnam in 1966 and was assigned to Kontum province. In March 1968, Paul and his comrades were assigned the mission of searching and capturing backpacks at a Vietnamese troop base. He then sent the diary to his mother in the US to keep it safe. He named it the Kontum diary. This was also the name of his book, published in 1996, where he described how the Kontum diary changed his life.
