Anyone who falls into the habit of thinking and expecting the best of his subordinates at all times is, for that reason alone, unsuited to command an army. -Carl von Clausewitz, On War, 1832

On War is Carl von Clausewitz’ masterpiece on war and military strategy, which was written between 1816 and 1830 and was published posthumously by his wife Marie von Clausewitz (nee von Bruhl) in 1832.

Three main concepts of war stand out: war should be seen as an instrument of politics; the military objectives in war that support one’s political objectives fall into two types: war to achieve limited aims and war to disarm the enemy; and the course of war will tend to favor the party with the stronger emotional and political motivations, but especially the defender.

This edition is the classical translation of On War (1873) by Col. J.J. Graham, with an introduction and notes by Colonel F.N. Maude, published in three volumes. A must-read for military historians and theorists, policy makers, and anyone interested in understanding the philosophy and concepts of war.
