The capture of German Poznan opens the way for Soviet troops to Berlin. But the fascists do not think of giving up. They defend themselves to the last, turning the city into an impregnable fortress with concrete fortifications and unprecedented firepower. At the forefront of our attack is the battalion of Major Prokhor Burmistrov. The fighters, meter by meter, conquer important strategic space from the enemy until they run into a labyrinth of ancient stone walls. But to stop means to disrupt the offensive. Burmistrov decides to take a desperate step: if you can’t get around these walls, then you need to go... through them... Novels about the Great Patriotic War are exceptional in their truth. The roar of distant explosions, the smell of gunpowder, the clanging of tracks - the terrible signs of war come to life again on the pages of books written by the grandchildren of those who reached Berlin back in 1945.
