The Battle of the Ice is approaching. Riot policeman Vasily Burtsev, who found himself in the thirteenth century, has two goals: to return his kidnapped wife and stop the onslaught of German aggressors on Rus'. Moreover, the first problem cannot be solved without solving the second. But how to achieve victory if not only the order’s “pig” will participate in the coming battle, but also the new ally of the crusaders - the SS Zeitkommando? The Nazis, thrown into the past, intend to change the course of history. Submachine gunners with Schmeisers, heavy motorcycles with machine guns in their sidecars, tanks and Messerschmitts - this is the kind of enemy the Russians will have to deal with on Lake Peipsi. No chance to win the battle? Burtsev, who joined the army of Alexander Nevsky, does not think so. The book is published in a new, original edition.
