The battle known for the siege lasting 77 days is the one at Khe Sanh. This battle took place during the Vietnam War between January 21 and April 8, 1968. The U.S. Marine Corps, along with supporting Army forces, occupied a remote base in northwestern Quang Tri Province, which was besieged by North Vietnamese forces. The length of the siege, 77 continuous days, is significant because it highlighted the difficulties faced by the troops in a harsh environment while being surrounded and targeted by enemy forces.

The duration of the Khe Sanh siege allowed for various combat strategies to be employed and demonstrated the challenges of supplying and reinforcing troops in a prolonged engagement. The battle gained notoriety not only for its length but also for the immense media coverage it received, impacting public perception of the Vietnam War.
