In A Nasty Little War, top Russia historian Anna Reid offers a sweeping and deeply researched account of the conflict. Initially launched to prevent Germany from exploiting the power vacuum in Eastern Europe left by the Russian Revolution, the Intervention morphed into a bid to destroy the Bolsheviks on the battlefield. But Allied armaments, supplies, and loans could not prevent Russia's anti-Bolshevik armies from collapsing, and the Allies were forced to retreat in defeat. The humiliation sapped British imperial swagger, chastened American idealism, and stoked militarism and nationalism in France and Germany. Combining immersive storytelling with deep research, A Nasty Little War reveals how the Allied Intervention reshaped the West's relationship with Russia.
