War...is an act of violence intended to compel our opponent to fulfil our will' 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 though. In line with Napoleon's military actions, Clausewitz illustrated the need to annihilate the enemy and to 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 well-being of the nation. Combining military theory and practice, On War has had a profound influence on subsequent thin king on warfare. This edition contains a detailed introduction examining Von Clausewitz's skill and reputation as a writer, philosopher and political thinker, as well as a bibliography, notes and a glossary.
