Intro. The 81-day and night-long battle at Quang Tri Citadel in 1972 is a shining symbol of courage and the spirit of sacrifice for national independence. Amidst the fierce rain of bombs and bullets, every inch of land here was soaked in the blood and bones of thousands of soldiers to create an 'immortal calyx'. That spirit of steel not only protects a strategic landmark but also affirms the resilient and never-subdued will of the Vietnamese people in the face of all enemies.
