The Great War was the first conflict to draw men and women into uniform on a massive scale. From a small regular force of barely 250,000, the British Army rapidly expanded into a national force of over five million. A Nation in Arms brings together original research into the impact of the war on the army as an institution, gives a revealing account of those who served in it and offers fascinating insights into its social history during one of the bloodiest wars.

A comprehensive new history of the shaping and performance of the British army during the First World War.

The colossal scale of World War II required a mobilization effort greater than anything attempted in all of the world's history. The United States had to fight a war across two oceans and three continents--and to do so, it had to build and equip a military that was all but nonexistent before the war began. Never in the nation's history did it have to create, outfit, transport, and supply huge armies, navies, and air forces on so many distant and disparate fronts. The Axis powers might have fielded better-trained soldiers, better weapons, and better tanks and aircraft, but they could not match American productivity. The United States buried its enemies in aircraft, ships, tanks, and guns; in this sense, American industry and American workers, won World War II. The scale of the effort was titanic, and the result historic. Not only did it determine the outcome of the war, but it transformed the American economy and society. Maury Klein's A Call to Arms is the definitive narrative history of this epic struggle--told by one of America's greatest historians of business and economics--and renders the transformation of America with a depth and vividness never available before.
