The Tet offensive attack on the US Embassy took place on the early morning of 31 January 1968 when a 19-man Vietcong (VC) sapper team attempted to seize the US Embassy in Saigon at the start of the VC's Tet offensive. While the VC successfully penetrated the embassy compound, they were unable to enter the chancery building and were pinned down by security forces, with the lone survivor eventually surrendering to US forces. Notwithstanding the attack's failure it had a profound political and psychological impact in the United States.
