Carl von Clausewitz’s On War is the most significant attempt in Western history to understand war, both in its internal dynamics and as an instrument of policy. Since the work’s first appearance in 1832, it has been read throughout the world, and has stimulated generations of soldiers, political leaders, and intellectuals. First published in 1976 and revised in 1984, Michael Howard and Peter Paret’s Princeton edition of Clausewitz’s classic work has itself achieved classic status and is widely regarded as the best translation and standard edition of On War in English. This feature-rich edition includes an essay by Paret on the genesis of Clausewitz’s book, an essay by Howard on Clausewitz’s influence, and an essay by Bernard Brodie on the continuing relevance of On War. In addition, Brodie provides a lengthy and detailed commentary on and guide to reading On War, and the edition also includes a comprehensive index.
