Perhaps the most important book on military strategy ever written, Carl von Clausewitz’s On War has influenced generations of generals and politicians, has been blamed for the unprecedented death tolls in the First and Second World Wars, and is required reading at military academies to this day. But On War, which was never finished and was published posthumously, is obscure and fundamentally contradictory. What Clausewitz declares in book one, he discounts in book eight. The language is confusing and the relevance not always clear. For a book that has truly changed the world, On War is extremely difficult for the general reader to approach, to reconcile with itself, and to place in context.
Hew Strachan, one of the world’s foremost military historians, answers these problems in this fascinating book. He explains how and why On War was written, elucidates what Clausewitz meant, and offers insight into the impact it made on conflict and its continued significance in our world today.

A century has passed since the outbreak of World War I, yet as military historian Hew Strachan argues in this brilliant and authoritative new book, the legacy of the “war to end all wars” is with us still. The First World War was a truly global conflict from the start, with many of the most decisive battles fought in or directly affecting the Balkans, Africa, and the Ottoman Empire. Even more than World War II, the First World War continues to shape the politics and international relations of our world.
Strachan has done a masterful job of reexamining the causes, the major campaigns, and the consequences of the First World War, compressing a lifetime of knowledge into a single definitive volume tailored for the general reader. Written in crisp, compelling prose, The First World War re-creates this world-altering conflict both on and off the battlefield-the clash of ideologies between the colonial powers at the center of the war, the social and economic unrest that swept Europe both before and after, the military strategies employed with stunning success and tragic failure in the various theaters of war, the terms of peace and why it didn’t last.
