During the Polish–Soviet War fought from February 1919 to October 1920 (ended by armistice in March 1921) between Soviet Russia and the Second Polish Republic – in the aftermath of World War I in Europe – the Polish order of battle included broad disposition of personnel, strength, organization, and command structure.
[1][2] In late 1920, the Polish Army had a total of 23 infantry divisions and nine cavalry brigades.
[3] Frequently, the infantry divisions were divided for specific tasks, with the resulting brigade-sized formations being called 'groups'.
[3] Larger ad hoc formations of more than a single division were called operational groups (Grupa operacyjna) rather than corps.
