U.S. and South Vietnamese Marines were struggling to crush the remnants of North Vietnamese forces in Hue's Citadel. Early on the morning of Jan. 31, 1968, as Vietnamese celebrated the Lunar New Year, or Tet as it is known locally, Communist forces launched a wave of coordinated surprise attacks across South Vietnam. The campaign, one of the largest of the Vietnam War, led to intense fighting and heavy casualties in cities and towns across the South. (AP Photo/Al Chang, File)
