BATTLE // April 1, 1919

Vilna offensive

Name: Vilna offensive
Start: 1919-04-01
End: 1919-04-01
Location: Vilna offensive

Significance

The Vilna offensive secured Vilnius for Poland after three days of street fighting against the Red Army in April 1919, marking one of the earliest major Polish territorial gains of the Polish–Soviet War. The Red Army's retreat following the city's capture allowed Polish forces to extend control well beyond Vilnius itself, with Lida, Pinsk, Navahrudak, and Baranovichi also falling to Polish hands during the same operation. This combination of gains pushed the front line substantially eastward in the war's opening phase, establishing a broad Polish foothold in the contested borderlands and complicating Soviet efforts to consolidate control over the region.

Tactics

The Polish assault involved street fighting within Vilnius over three days from April 19–21, 1919, resulting in the city's capture and the Red Army's withdrawal. The overview does not describe specific maneuvers, terrain use, or unit dispositions beyond this.
