Southern Russia intervention

The Southern Russia intervention was an Allied military intervention in present-day Ukraine between December 1918 and April 1919 on the Black Sea shores of the former Russian Empire, as part of the Allied intervention in Russia after the October Revolution. The intervention was an involvement in the Russian Civil War on the side of the White movement, but lacking in forces and sympathy among the local population, it was a failure that ended with the evacuation of the territory.
