Vietnam was the war that tore America apart.
By the beginning of 1968 it had devolved into a nightmare of body counts, B-52 bomber attacks and frustrating guerrilla raids. Then, on the most holy day on the Vietnamese calendar, the Northern Vietnamese unleashed their greatest mass assault of the entire war - the Tet Offensive. It proved to be a game changer, setting in motion a process that would see America lose its first ever war.
