(VIETNAM HISTORY) Major effort by the National Liberation Front ("Viet Cong") and the PAVN to defeat the US-backed puppet regime in Saigon (the putative Republic of Vietnam"). The Tet Offensive began 31 January 1968 and was suppressed around 24 February.
In Saigon, NLF forces attacked the presidential palace, the airport, the ARVN headquarters, and US Embassy. The US and ARVN forces, who were caught off guard, quickly responded and within a week had recouped most of the lost territory. The NLF held out the longest in the pre-colonial capital of Hue, fighting back with great tenacity.
Prior to the Tet Offensive, the US military could claim it was well on its way to winning the war. Afterward, Gen. William Westmoreland admitted 200,000 more troops would be required to win the war, and US opposition to the war ballooned.
However, the NLF was nearly annihilated in the Offensive, with almost 60,000 killed.
