As part of the broader Polish–Soviet War of 1919–1920, the Polish Army sought to expand its eastern frontier and assert control over Vilnius, then held by the Red Army. The strategic and symbolic importance of the city drove Polish military planners to organize a dedicated offensive operation.
On April 16, 1919, Polish forces launched an offensive toward Vilnius. After three days of street fighting between April 19 and 21, Polish troops captured the city and forced the Red Army to withdraw. The offensive also resulted in Polish seizure of nearby towns including Lida, Pinsk, Navahrudak, and Baranovichi.
The Red Army's subsequent counterattacks in late April 1919 all failed to retake the city. Although Soviets briefly recaptured Vilnius in spring 1920 during a general Polish retreat, the offensive generated significant political controversy in Poland and internationally, affecting diplomatic relations in the region.
