Russian Civil War, 1920 Campaign

The Red Army invaded Poland in October, 1920 as a continuation of their pursuit of the remains of the White forces in the west of Russia. The Whites, under the command of their last-hope leader, Vrangel, were on their last legs. One of the principal Red commanders was cavalry officer Josef Stalin. The Poles pushed them back across the Curzon Line and their national borders into western Greater Russia. Lenin and Trotsky accepted this defeat in anticipation of the onset of Winter.  The Poles had a number of European military advisers in the background, among whom was one Charles De Gaulle. A few months later, ignoring Poland, the Red Army pushed south and drove the Whites through Crimea and into exile by evacuation across the Black Sea. The war was over.
