The book highlights and summarizes the experience of the positional massacre of the First World War. It tells how a situation arose in which the largest armies in Europe were deprived of the ability to maneuver and were forced to exhaust themselves for months in long battles, without obvious results. The book talks about the development of military thought and technical changes that occurred at that time, drawing parallels with our time. The book will help the reader understand how trench warfare works, how it should be waged, and whether there is a way out of it. The book consistently shows the possibilities of maneuvers in trench warfare and tells about ways out of the deadlock of trench battles.
