Skirmish mission (USA, Autralia,South vietnam VS North vietnam, Vietcong)
The Tet Offensive was a military campaign during the Vietnam War that was launched on January 30, 1968 by forces of the Viet Cong and North Vietnam against South Vietnam, the United States, and their allies. It was a campaign of surprise attacks that were launched against military and civilian command and control centers throughout South Vietnam, during a period when no attacks were supposed to take place
The operations are referred to as the Tet Offensive because there was a prior agreement to "cease fire" during the Tet Lunar New Year celebrations. Both North and South Vietnam announced on national radio broadcasts that there would be a two-day cease-fire during the holiday. Nonetheless, the Communists launched an attack that began during the early morning hours of 30 January 1968, the first day of Tet. In Vietnamese, the offensive is commonly called Tết Mậu Thân (Tet, year of the monkey). Military planners called it the "General Offensive and Uprising" (Cuộc Tổng tiến công và nổi dậy).
The Communists launched a wave of attacks on the morning of 30 January in the I and II Corps Tactical Zones of South Vietnam. This early attack did not lead to widespread defensive measures. When the main communist operation began the next morning the offensive was countrywide and well coordinated, eventually more than 80,000 Communist troops striking more than 100 towns and cities, including 36 of 44 provincial capitals, five of the six autonomous cities, 72 of 245 district towns, and the southern capital. The offensive was the largest military operation conducted by either side up to that point in the war.
The initial attacks stunned the US and South Vietnamese armies and took them by surprise, but most were quickly contained and beaten back, inflicting massive casualties on communist forces. During the Battle of Huế intense fighting lasted for a month resulting in the destruction of the city by US forces while the Communists executed thousands of residents in the Massacre at Huế. Around the US combat base at Khe Sanh fighting continued for two more months.
