The Eastern Front
Until recently, the eastern theater of the First World War was what Winston Churchill called “the Unknown War.” It was not overlooked, as other fronts were, but unknown; while people knew of some battles (Tannenberg), the assumption was that the Eastern Front was simply a mirror of the Western Front. Instead of trench warfare and stalemate, however, the Eastern Front was the war everyone expected: it featured mass armies making sweeping movements, breakthroughs leading to tremendous advances, and innovation in both tactics and technology. Yet while the conflict proved decisive for both Russia and Austria-Hungary, the ultimate decision came elsewhere.
