During the 19th and early 20th centuries. It was in Germany that military theorists who received worldwide recognition appeared. Their theories were then put into practice by German generals, who during this time plunged Europe into several bloody wars - including the world war. But even the defeat of Germany in 1918 did not put an end to this issue. It was the military theorists whose works are collected in this book who laid the foundations of the military tradition that ultimately led to the outbreak of a new - World War II. And even the latest military developments are based on the same ideas, put forward in many respects by the authors of this book. The book contains the works of leading military theorists in Germany, who revolutionized the art of war and laid the foundations of modern military art. The book is intended for a general reader interested in the history and theory of military art.
