About the book: 1966 / From besieged Leningrad, a submarine breaks through to the west. Her path is long and difficult - under bombing and shelling, through minefields and net barriers, through the curtains of ship patrols. Due to nearby explosions, instruments and mechanisms fail, and the steel of the body crumples and crumbles. Fires break out in the cramped compartments, and water gushes from the holes with a deafening whistle. It sells metal, although submarines are built from the best steel. Metal does not have enough safety margin. And people endure everything. They put out fires, seal holes, and make damaged mechanisms work. And the formidable ship goes out to the open sea, overtakes and sinks the enemy. The author of this book is a submarine engineer. He writes about what he himself saw and experienced during military campaigns. He writes about his comrades. And it turns out that these people are the most ordinary. It can be both scary and very difficult for them. And yet these are amazing people. Nothing will break them. Because they have a high goal in front of them and the sacred fire of love for the Motherland burns in their hearts.
