Surrounded by flames and crown fire that immediately spread over the nearby standing trees the firefighters got trapped amid a hellish firestorm.
Russian Ministry of emergencies published a video showing firefighters surrounded by fire.
They were fighting to contain the fire till nightfall when the bulldozers came to cut trees down along the inner edge of the burning circle and the crown fire was eventually contained.
"It was an emotional moment that I will never forget. When a tree falls it makes this loud sound and amid smoke and this blazing mess you can't see where it's falling and this is terrible as you just don't know what to do and what way to run," said Mikhail Chirkov, a senior firefighting specialist of the Nizhny Novgorod fire fighting unit.
To localize the fire on the escape routes tanker trucks and heavy equipment were sent to help.
Rescuers broke through to the ring of fire.
After almost a day of struggle, people managed to escape the fiery hell.
According to the emergency officials, not a single life or piece of equipment was lost.
