Publisher's abstract: The Battle of the Marne is one of the key moments of the First World War. Previously published in the “Military History Library” series, B. Takman’s book “The First Blitzkrieg. August 1914” ends on the eve of the Marne, on the evening of September 4, when “a new page of the world war silently turned over and opened.” This “new page” is the subject of the work of M. Galaktionov, which can be considered as a standard of military historical research. It combines a wealth of factual material with detailed and disciplined analysis, logic of presentation with brilliant literary language.
