The book of the famous military historian Andrew Roberts is replete with details and details showing in a new light the characters and logic of the behavior of the main actors of the world war on both sides of the conflict. The author, using unique, previously unpublished documents, talks about little-known heroes who determined the outcome of battles on the battlefield, about the valor, courage and courage of some, about the meanness and baseness of others, about the horrors and savages that made this war the bloodiest in the history of mankind.
