Imperial Russia's massive, if finally fatal contribution to the Allied war effort of 1914-17 involved huge numbers of men and some of the greatest battles of the war. The defeat at Tannenburg in 1914, and Brusilov's successful 1916 offensive against the Austro-Hungarians, were major events which had far-reaching effects on the Western fronts; and the attempts to keep the war effort going after the fall of the Tsar greatly influenced the course of the Bolshevik Revolution. This volume provides illustrated detail on the range of varied and colourful uniforms worn by the troops who played central roles in these events, many of which appear exotic to western eyes.
