War is the ultimate test of human endurance, pushing individuals and nations to their limits of strength, resilience, and ingenuity. Throughout history, many countries have faced wars, but few have matched the level of determination and endurance shown by Vietnam during the Vietnam War (1954–1975; a major proxy war of the Cold War between the Soviet Union and the United States (US)).
A powerful example of this unyielding spirit is the story of Vinh Moc tunnels—a testament to the courage and ingenuity of ordinary Vietnamese people determined to protect their families and way of life.
The Secret Lifeline of Con Co Island
During the Vietnam War, Con Co Island was a North Vietnamese stronghold defending against US air and naval attacks. Armed with surface-to-air missiles, Viet Cong forces disrupted the US bombing missions over Hanoi (formerly capital of North Vietnam) and blocked enemy landings. But to continue the fight, they needed food, medicine, and weapons, all of which came from a quiet fishing village, Vinh Moc, making it a key supply centre and a symbol of resistance during the war. Vinh Moc sat on the northern edge of the former demilitarized zone (near the Hien Luong Bridge, the dividing line between North and South Vietnam (two separate countries then)).
Vinh Moc in the Crosshairs
Under the cover of night, courageous villagers, disguised as fishermen to evade US patrols, regularly rowed across 28 kilometres of open sea to deliver supplies. Each trip was fraught with danger—one wrong move meant death.
It did not take long for the US to recognize that Vinh Moc was more than just a fishing village; it was a lifeline sustaining the enemy. Their response was swift and brutal—wipe it off the map.
A Storm of Fire
American warplanes unleashed relentless bombing campaigns on Vinh Moc. Homes were obliterated, rice fields were reduced to craters, and the land was transformed into a smouldering wasteland. But the villagers refused to surrender; instead, they dug trenches, rebuilt their homes, and continued their secret supply runs.
The bombings only intensified. By the mid-1960s, Vinh Moc had been nearly razed to the ground. Yet the spirit of its people remained unbroken.
Moving Underground
With their homes in ruins from endless shelling, the villagers and North Vietnamese Army soldiers made a bold decision that defied logic and fear: They would move underground.
Underground warfare was not new to Vietnam. Decades earlier, the Viet Minh, under Ho Chi Minh’s leadership, had used tunnels to evade the Japanese in World War II and the French during the First Indochina War. But this time, the tunnelling was not just a military tactic—it was a matter of survival.
Faced with relentless American bombings, the people of Vinh Moc had only one option: to disappear underground. Armed with shovels, determination, and an unbreakable will to live, they carved out a new existence beneath the earth.
Vinh Moc’s Underground Fortress
At first, the villagers dug 10-metre-deep tunnels, just enough to escape standard bombings. But as the American forces adapted, deploying bunker-busting bombs, the villagers were forced to dig deeper. Located on a sea-facing hill composed of red basalt, a porous yet sturdy rock, the tunnels could be excavated by hand while maintaining structural integrity. By the time they were finished, the network extended 30 metres underground—a nearly indestructible fortress requiring no support beams except at entry and exit points.
For 2 years, working over 18,000 labour days, the villagers and soldiers dug a complex tunnel system. Completed in 1967, the impressive 2000-metre-long tunnel network featured six hilltop entrances and seven shoreline exits leading to the South China Sea, which allowed for supply runs and quick escapes. Every time American bombers flew overhead, the villagers and soldiers disappeared underground, safe in their hidden world.
The Ingenious Underground World of Vinh Moc
Fully functional, the tunnels turned into a thriving village completely equipped for survival. Here are the facilities it had:
1. Ventilation
Fresh air supply: Multiple ventilation shafts, at least 5 metres deep, placed throughout the tunnels, ensured continuous airflow, preventing suffocation.
2. Concealed kitchens
Hoàng Cầm stove: A special stove and chimney system was used for cooking, which dissipated the smoke (through long underground bamboo vents), thereby avoiding detection by enemy planes.
3. Drainage
Sloped tunnels: The tunnels were designed to drain rainwater naturally, preventing flooding.
4. Essential living spaces
Sleeping quarters: Small alcoves provided private resting spaces for families.
Medical stations: Areas were set up for treating the sick and injured.
School and meeting rooms: Classrooms and communal halls allowed education and gatherings.
5. Defence
Camouflaged entrances: Covering the entrances with natural vegetation ensured invisibility from above.
Watch posts: Guards monitored enemy activity, warning the villagers of danger.
The tunnels had three levels:
First level (12–15 metres deep): It served as a warehouse for food, weapons, and supplies to sustain both the underground community and the resistance forces on Con Co Island.
Second level (20 metres deep): This floor housed the Party Committee, People’s Committee, and Military Command, where battle strategies were planned.
Third level (28 metres deep): Families lived here, raised children, and found a way to maintain a sense of normalcy. Seventeen children were born here—a testament to life continuing even in wartime.
At any given time, 60 to 90 families lived alongside the soldiers in this underground sanctuary.
Seven Years in Shadows
For 7 years (1966–1972) the tunnels shielded the villagers from one of the most intense bombing campaigns of the war. Incredibly, not a single life was lost to airstrikes. Only one bomb ever struck the tunnels directly—but it failed to detonate. Instead of fearing it, the villagers repurposed the crater into a ventilation shaft, a perfect example of their resourcefulness.
Even underground, vigilance was key. At the first sign of enemy aircraft, a guard would strike a bomb casing, sending a metallic warning through the tunnels. And the villagers disappeared into the earth within seconds, before the sky erupted in flames.
Emerging from Darkness
By 1969, as the war raged on, half the villagers had been evacuated to Nghe An Province for safety. When the air raids finally ended in 1972, the surviving villagers slowly emerged from their subterranean refuge only to find their homeland in ruins. A year later, those who had fled to Nghe An returned, reuniting with their families and beginning the long and arduous journey of rebuilding their lives.
Rising from the Ashes
War brings unimaginable loss, but those who rise from its ashes do so with renewed strength and purpose. The Vietnamese were no different. Despite having endured not only physical destruction but also deep emotional and psychological scars, they rebuilt.
Once-bombed cities like Hanoi (now capital of Vietnam) and Saigon (now Ho Chi Minh City) have now transformed into thriving urban centres. Even the devastating effects of Agent Orange (a herbicide mixture used by the US military in the Vietnam War, causing lasting devastation) did not break the Vietnamese; rather, they became symbols of resilience. Today, Vietnam is a rapidly growing economy—proof that a nation can heal and move forward.
The Legacy of Vinh Moc
The story of the Vinh Moc tunnels is a powerful reminder that true strength comes not from weapons but from the will to survive, adapt, and rebuild. It highlights the resilience, ingenuity, and unity of a community determined to overcome the impossible.
Tips for Visitors:
• Best time to visit: February–August, during dry season

• Book a guided tour or private taxi from Hue.
• Arrive early in the day to avoid crowds.
• The visit will take 1–2 hours, depending on your interest.
• Visit the museum first for deeper insights into the tunnels.
• Wear comfortable shoes; the floors are uneven and slippery.
