Battle of Vilnius (January 1919)

The Battle of Vilnius in January 1919 (Polish: Walki o Wilno, Russian: Сражения за Вильно) were a series of battles fought in Vilnius between the pro-Polish Self-Defence of Lithuania and Belarus who were initially against the Imperial German Army retreating from the city and the Bolshevik paramilitaries (December 31, 1918 – January 3, 1919) and then against the attacking Red Army (January 4–5, 1919). The fighting resulted in the temporary capture of most of the city of Vilnius by the Poles, who eventually had to retreat before the Red Army came.
