von Clausewitz, Carl: On War. V1. 8 Nov 2010
 

von Clausewitz's seminal work on warfare.

Description from the Penguin Classics edition:
Writing at the time of Napoleon's greatest campaigns, Prussian soldier and writer Carl von Clausewitz created this landmark treatise on the art of warfare, which presented war as part of a coherent system of political thought. In line with Napoleon's own military actions, he illustrated the need to annihilate the enemy and make a strong display of one's power in an 'absolute war' without compromise. But he was also careful to distinguish between war and politics, arguing that war could only be justified when debate was no longer adequate, and that if undertaken, its aim should ultimately be to improve the wellbeing of the nation.

from www.clausewitz.com/:
The Prussian military thinker Carl von Clausewitz is widely acknowledged as the most important of the major strategic theorists. Even though he's been dead for over a century and a half, he remains the most frequently cited, the most controversial, and in many respects the most modern.

This work was translated into English by Colonel J.J. Graham in 1874.
