On 24 March 1942, the first stage of the evacuation of the soldiers serving in the so-called Anders Army from the Soviet Union to Persia began. About 78,000 exiles, who joined the Polish army and 37 thousand civilians, including about 18,000 Polish children were evacuated in total.

The Polish-Bolshevik war broke out on 14 February 1919. The site of the first confrontation was the town of Mosty near Szczuczyn in the Grodno region, where Polish Army units halted the Red Army’s march.
