Everybody knows them as the national Russian hero and holy prince Alexander Yaroslavovich Nevsky. However, knowledge about him is most often limited to the brilliant victory over the dog knights on the ice of Lake Peipsi. How did Alexander live before this feat? How was his childhood and adolescence? A fascinating book by Dmitry Abramov talks about this. The author is distinguished by his deep knowledge of the historical realities of that time. The book describes in detail the military equipment and military tactics of the medieval Russian army. The geographical range of events described in the book is also wide, from the Mongolian steppes to the Byzantine capital. Political intrigues, war, the youthful love of the young prince and his military exploits - all this will not leave any lover of Russian history indifferent.
