The Cossacks were the best warriors of all eras in which they lived. Napoleon said that with the Cossacks he would have conquered the whole world. The Cossacks prevailed not only with their military skill, but also with their bestial strength, endurance and agility, as well as the battle strategy inherent in them by nature itself. Life on the outskirts of the Moscow state, which was always at war with its formidable neighbors, taught them to win. They were the true gods of war! Dmitry Agalakov's new novel is dedicated to four legendary Volga Cossacks - Ermak Timofeevich, Ivan Koltso, Matvey Meshcheryak and Bogdan Barbosh. Their struggle with the Polish-Lithuanian Commonwealth on the Dnieper, the victory over Khan Kuchum, as well as the merciless war on the Volga and Yaik with the Nogai Horde of Prince Urus - another worst enemy of the Muscovite kingdom.
