The Tet Offensive The Tet Offensive was marked as a major turning point in the war. In the end of January to early February, the Vietnamese celebrate Tet, or the Lunar New Year. On January 31, 1968, North Vietnam soldiers attacked South Vietnam cities at 3 a.m. This takeover of the South lasted until February 25, with deaths totaling at 3,470 and 12,062 wounded American and Southern Vietnam troops. Prior to the attack, American citizens were under the impression that the United States was winning the war. When word got back home that this Northern Force, which had been portrayed so esoteric and savage-like, had a major victory, the American people were shocked. With the Tet Offensive, opinions about the war changed throughout the country.
