The book of Kaluga historians and search engines A. Ilyushechkin and M. Mosyagin is dedicated to one of the tragic pages of the Great Patriotic War - a fierce struggle for control over the Warsaw highway, the focus of which fell on the territory of several heights and villages in the Baryatinsky district of the Kaluga region, adjacent to this most important transport artery. The battle for Zaitseva Gora - such a collective name was given to the battles - lasted more than a year, from February 1942 to March 1943.
