The Battle of Lida took place on 16 and 17 April 1919 around the city of Lida during the Polish–Soviet War of 1919–20. During World War I Lida was occupied by the German troops. In 1919 the Red Army briefly established Soviet power here. Polish troops under General Józef Adam Lasocki reached the outskirts of the town, which was an important railroad junction, in early March 1919. On April 15 they resumed their advance and on April 17 they captured Lida, as a screening operation to the taking of Vilnius, which was the main target of Polish operation. Background In early 1919, the situation on the Polish–Ukrainian front stabilized (see Polish–Ukrainian War). Further to the north, Polish – Soviet frontline went along the line Brest – Pinsk – Baranavichy – Skidzyelʹ. Southern sector of the Polish – Soviet frontline (near Byaroza), was protected by the so-called Podlasie Group of the Polish Army concentrated, under General Antoni Listowski, while in the north (around Vawkavysk), stationed the 1st Lithuanian–Belarusian Division, commanded by General Wacław Iwaszkiewicz-Rudoszański. In early March 1919, Polish forces initiated a series of local offensives: on March 2, Poles captured Slonim, three days later Pinsk, and their units reached Lida. In April 1919, Headquarters of the Polish Army had to make a strategic decision: whether to continue fighting the Ukrainians in Eastern Galicia and Volhynia, or to move bulk of the forces to Polesia and Belarus, and face the Soviets. Józef Piłsudski chose the latter option, probably for personal reasons, as he was emotionally attached with the city of Vilnius. In early April 1919, Polish units concentrated along the line of the Yaselda River and the Oginski Canal. Soviet forces controlled the towns of Vilnius, Lida, Baranavichy and Luninets, while German units of the Ober Ost remained east of Grodno. The area of Lida was guarded by weak Soviet forces, and Polish troops took advantage of it, capturing Eišiškės, located between Lida and Varėna. Following the order of Polish Headquarters, both Vilnius and Lida were to be captured in a simultaneous operation. Forces, sent to Lida under General Józef Lasocki, consisted of the following units: 1st Battalion of 2nd Legions' Infantry Regiment (Captain Emil Czaplinski), 1st Battalion of 3rd Legions' Infantry Regiment (Captain Waclaw Zborowski), 3rd Battalion of 4th Legions' Infantry Regiment (Captain Stefan Jazdzynski), a battery of field artillery and two batteries of heavy artillery, two infantry battalions of
