BATTLE // November 18, 1918
Soviet westward offensive of 1918–1919
Overview
The Soviet westward offensive of 1918–1919 was part of the campaign by Soviet Russia into areas abandoned by the Ober Ost garrisons that were being withdrawn to Germany following that country's defeat in World War I. The initially successful offensive against the Republic of Estonia ignited the Estonian War of Independence which ended with the Soviet recognition of Estonia. Similarly, the campaigns against the Republic of Latvia and Republic of Lithuania ultimately failed, resulting in the Latvian–Soviet Peace Treaty and Soviet–Lithuanian Peace Treaty respectively. In Belarus, the Belarusian People's Republic was conquered and the Socialist Soviet Republic of Byelorussia proclaimed.

Significance
The Soviet westward offensive of 1918–1919 unfolded in the vacuum left by the withdrawal of German Ober Ost garrisons following Germany's defeat in World War I. Soviet Russia moved into these abandoned territories with a force of roughly 285,000 against approximately 70,000 opposing troops across multiple fronts. Results were mixed and consequential: the advance into Estonia triggered the Estonian War of Independence, which concluded with Soviet recognition of Estonian sovereignty. Campaigns into Latvia and Lithuania similarly failed, producing the Latvian–Soviet Peace Treaty and the Soviet–Lithuanian Peace Treaty. In Belarus, however, Soviet forces succeeded in displacing the Belarusian People's Republic and establishing the Socialist Soviet Republic of Byelorussia. The offensive thus produced divergent political outcomes—independent statehood for the Baltic republics and Soviet consolidation in Belarus—defining the postwar political map of the region during the broader Russian Civil War.
