Giap served as
minister of defense and commander-in-chief of the People's Army of Vietnam. With the outbreak of hostilities with South Vietnam, and later the United States, Giap led North Vietnam's strategy and command. In 1967, Giap oversaw the planning for the massive
Tet Offensive. While initially against a conventional attack, Giap's goals were both military and political. In addition to achieving a military victory, Giap desired the offensive to
spark an uprising in South Vietnam and show that American claims about the war's progress were wrong.
