Cause

During the Polish-Soviet War, Alexander Yegorov's forces, including Semyon Budyonny's 1st Cavalry Army, targeted the city of Lwów from mid-June 1920 as part of a broader Soviet offensive into Polish-held territory. The city's inhabitants responded by raising three infantry regiments and two cavalry regiments and constructing defensive lines.

Event

On August 16, 1920, the Red Army crossed the Bug River and launched a full assault on Lwów, reinforced by eight additional divisions of Red Cossacks. Heavy fighting ensued on both sides for three days, but the assault was ultimately halted and the Red Army withdrew from its positions around the city.

Consequence

The failure to take Lwów, combined with the decisive Polish victory at the Battle of Warsaw and Polish successes at Komarów and Zadwórze, forced Russian forces to retreat entirely from the region. In recognition of the city's defense by locally raised volunteers, Lwów was awarded the Virtuti Militari medal on 11 November 1920.
