The Battle of Huế, was a major battle in the Tết Offensive launched by North Vietnam and the Việt Cộng during the Vietnam War. Initially losing control of most of Huế and its surroundings, the combined forces of South Vietnam and the United States gradually recaptured the city after a little over one month of intense fighting. The battle was one of the longest and bloodiest of the war, causing it to negatively affect the American public perception of the war. The battle is widely considered to be one of the toughest and most intense urban battles ever fought.
