If you have ever visited war museums or revolutionary sites, the chances are that you will have seen a wood-burning stove model where you can cook food, but no firelight nor smoke can be seen coming out of it.

Today, if you are an 18-year-old joining the military for the first time, you will learn how to dig a double wood stove to cook for up to 60 people within a short period.

Anyone spending time in the military cannot forget the popular double stove that is the Hoang Cam stove. The three words: Bep Hoang Cam stands for warm and freshly cooked meals anywhere the soldiers are stationed.

In a recent social media post about how soldiers cook, thousands of people have expressed their respect and admiration for the creation of this specific stove, which helped save many lives, and fed millions of soldiers through several wars since 1952.

"If anyone deserves to be a hero, Army Captain Hoang Cam is the hero of all heroes! We all owe him our gratitude," said Nguyen Phu Ninh.

Many veterans have shared their experiences with the Hoang Cam stove.

Tran Van Hung wrote, "I marched along the Truong Son Mountain Range during the anti- American war. And in all the fierce battle on our post, we all had hot food and boiling water thanks to the Hoang Cam stove."

Another veteran Trinh Hoang wrote, "We always dug up a Hoang Cam stove to cook food. No smoke by day, no light by night. The US recon aircraft OV-10 could not detect us. That decreased our human losses enormously along the legendary Ho Chi Minh Trail."

Making of a kitchen king

In the war against French colonialists in the mid-1950s, the young Vietnamese army, founded only in 1944, lacked everything from staple food and ammunition to antibiotics and transport. Troops mostly walked from base camps to battlefields. Heavy losses were inevitable.

When his unit took part in the Hoang Hoa Tham and Hoa Binh campaigns in 1952, military cook Cam saw the human losses his comrades had suffered. There were so many mortalities, and those who survived were weakened due to lack of nutrition. The two main reasons were that the enemy warplanes bombed his troops, and the daily food supply was inadequate.

Cam realised that the war was getting fiercer every day. One issue was the cooking process. When he cooked at night, the firelight can be spotted by enemy recon aircraft, and during the day, smoke showed the place where the soldiers were stationed. There were many incidents when a cook started burning his stove, a cloud of smoke came out, and enemy planes would soon arrive and bomb and shell their garrison. Many died from such attacks.

The cooks switched to prepare food at night only. When they heard an airplane coming, they would use water to stamp out the fire. But the rice was left uncooked, making it hard to consume. Also, food cooked at night that had to be eaten during the day was cold, hardly the morale-boosting meals a soldier needs to fight a war. After all, an army is said to march on its stomach.

Cam tossed and turned for many days and nights. He wanted to help reduce the human losses.

The story about how the kitchen stove was conceived has become a legend, retold countless times in and out of military circles. One morning, during his early shift, Cam took a walk along the stream and saw the smoke hanging under a thatched roof. He suddenly thought of a wood stove, which diverts its smoke so it would not come up in the air and reveals the fire underneath. If successful, it would mean he could cook food during the day, and no smoke would be seen.

Cam started working on channelling the smoke into a system of tunnels like a rat's cave. He put it on paper, dug into a hill and tried digging various types of stoves. He dug dozens, with many tunnels that spread the smoke around the ground surface. He then tried to cook rice on that wood stove. The results were not bad, but the flickering light was still seen, and the smoke still came up, though lighter.

Cam didn't give up. He dug dozens more, doubling the tunnel lengths and adding more turns. He would place tree branches on the tunnels and then cover them with dirt so no visible smoke could come out. He also dug a large hole in front of the stove, covered with a plastic mat, where he could store cooking tools on top, and cover the light. Underneath, the hole was like a smoke cell, giving more air for the fire to burn stronger.

At last, Hoang Cam invented the fire stove as he wished. A fire stove dug into a hill's foot or on the ground, with the smoke channels like a squid's tentacles. The channels were then covered with tree branches and damp dirt on top. Smoke from the furnace spread out into the channels and was screened and blocked by the ground. It rose but looked just like the morning mist and quickly vanished.

Little did Cam know then his invention would still be used in the army kitchens 70 years later, long after he died.

In the early days of the young democratic republic, people thought little about possession and private property. Patent registration didn't even exist, and intellectual property was a concept that would come to Vietnam some half a century later.

During those days, the Vietnamese offered all they had to the common cause to fight for freedom from French rule, giving up their houses, gold savings, and privileges. In that same spirit, Cam's invention soon became the model stove made across all regiments of the people's army. All soldier-cooks lauded it.

The double wood stove invented by Cam fit perfectly with soldiers during the war: it's close, not revealing firelight, and smoke stays close to the ground. Having dug this stove, cooks can cook rice on one stove and meat or veggie soup on the other. Chefs can cook during the day and at night without fear of detection by enemy recon warplanes. Soldiers in battle could have hot rice and soup every day.

In October 1952, the army gave this new kitchenette a name: the Hoang Cam stove, after its inventor.

Revolution of its own

Since its birth until now, the Hoang Cam stove has been widely used in the Vietnamese army and is a must for use in all units.

This invention gave soldiers hot food every day, and they got hot water during winter. Frontline medical staff had boiling water to sterilise their operation tools. This creation brought enormous practical benefits when soldiers had to move from one location to another.

Since cooks were not afraid of enemy recon airplanes whenever they started a fire. The soldiers didn't have to eat cold food cooked the night before.

In his memoir, Road to Điện Biên Phủ by General Vo Nguyen Giap, he wrote of the stove: "It would have been a shortcoming if I won't mention here an initiative which improved the life and health of our soldiers on battlefields."

When the resistance war ended, Hoang Cam was awarded the Dien Bien Soldier Badge and the Victory Order, third class. He was among the proud soldiers marching in their battalion to Hanoi on October 10, 1954, two years after his creation solved the daily food issue on the frontline.

Demobilisation

In 1958, the entire army shifted to a peaceful period, cutting the number of active soldiers. Thousands of soldiers who had gone through the actual war were demobilised to go home with their families or moved to other workplaces, including cooperatives and factories.

In early 1959, Hoang Cam was demobilised from the army as a lieutenant.

For many years he lived with his family in Tam Dao Town, working in the local cooperative. He had taught fellow neighbours to make icecream sticks from bamboo, then he packed the sticks onto his bicycle and cycled to Hanoi to sell for Thuy Ta ice cream shop by Hoan Kiem Lake. According to the local cooperative, during his tenure as head of the cooperative, he sold 12 tonnes of ice cream sticks, earning money for cooperative members to buy rice.

This prompted avid veterans to laud him as the Labour Hero, an honour bestowed by the President to individuals with outstanding work achievements.

His family later moved to Hanoi where he died at Military Hospital 108 at 80 years of age. He was promoted to the rank of Captain posthumously.

He perished, but his legacy lived on. Today Bep Hoang Cam is still in the syllabus of all military academies. It was even mentioned in one of the most sung war songs by composer Huy Du, Let's Turn the Fire on!

Hoang Cam's incredible legacy will surely never be forgotten.
