Defeat in 1918 left many of the losers recalcitrant, Germany foremost. Drawn to totalitarianism under a new leader in the 1930s, it first made common cause with other discontented nations, including Italy and Spain, which waged wars of their own in that decade, then in 1939 embarked on a second European war to reverse the outcome of the First. That rapidly became a World War, whose character was dominated by the development and refinement of the embryo technology of 1918. This volume covers the blitzkrieg of 1939-41, the war in Russia, and the Anglo-American counter-offensives in Africa, the Mediterranean and North-West of Europe, concluding with the campaigns of 1945 that resulted in the final defeat of Nazism in Europe.
