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 The author, using unique, previously unpublished documents, talks about little-known heroes on the field battles that determined the outcome of the battles, about the valor, bravery and courage of some, about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