Battle of Warsaw (1920)
The battle of Warsaw was fought from August 12–25, 1920 as Red Army forces commanded by Mikhail Tukhachevsky approached the Polish capital of Warsaw and the nearby Modlin Fortress. On August 16, Polish forces commanded by Józef Piłsudski counterattacked from the south, disrupting the enemy's offensive, forcing the Russian forces into a disorganized withdrawal eastward and behind the Neman River. Estimated Russian losses were 10,000 killed, 500 missing, 30,000 wounded, and 66,000 taken prisoner, compared with Polish losses of some 4,500 killed, 10,000 missing, and 22,000 wounded.
Battle of Stoczek
The Russian Army commanded by Field Marshal Hans Karl von Diebitsch entered Poland on 4 February and started an advance towards Warsaw. 2nd Mounted-Jaeger Division—2 brigades of 2 regiments, each consisting of 3 troops of 2 squadrons—under baron Teodor Geismar, who assumed command just 9 days earlier, entered Poland on 13 February and was marching to the Brest road with some 20 10-pounder guns of field artillery attached. The main forces of Field Marshal Dybich were marching towards Warsaw from the direction of Lublin.
General Józef Dwernicki, commander of the Polish forces in the area, organised a Polish Division. He managed to gather 14 cavalry squadrons, 3 infantry battalions and 6 3-pounder guns—approximately 4,700 men at arms altogether, including 2,200 cavalrymen—and on 10 February he crossed the Vistula River.
