The U.S. embassy in Vietnam was considered U.S.
soil in Vietnam. During the Tet Offensive, the embassy was attacked by Viet
Cong commandos who rode in on bicycles as civilians and used explosives to enter
the building. Some people evacuated the embassy while other barricaded themselves
on the second floor. In the end, all of the Viet Cong commandos were slaughtered.
Finally, after the U.S. had pulled out of the war, the North Vietnamese Army
occupied Saigon and U.S. Diplomats boarded helicopters to leave Vietnam. The
last two casualties of the war were two Marine guards who had been killed by
mortar fire while protecting the diplomats.
