There is no more hushed up, more slandered, more damned and forgotten war in our country than the First World War (1914-1918). The fate of her heroes is bitter. Due to historical circumstances, they did not receive any anniversary medals, no pensions, no museums, no eternal flames, no flowers on Victory Day... This book is a modest tribute to those who did not return from the bloody fields of Galicia, Volyn, Poland, Lithuania, Latvia , Belarus, over whom the cold waters of the Baltic or the Black Sea closed forever. Twelve essays are presented to the reader’s attention - short biographies of people who forever inscribed their names in the history of the First World War. This is an outstanding commander and commander of a warship, the son of the Grand Duke and a simple Don Cossack, the first fighter pilot in Russia and a nurse, a military priest and a dashing hussar officer... The biography of each hero can be traced in close connection with the fate of Russia, which is why upon reading a holistic picture emerges about a great and tragic era. The book is equipped with appendices, from which the reader will learn a lot of useful information about the organization and structure of the Russian Imperial Army, military ranks and awards.
