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 Warsaw (1831)
The Polish plan was based on fixed defence of the front line, with the forces under Umiński and Dembiński behind the second line of defences and acting as a mobile reserve, together with divisional artillery and cavalry. Umiński's Corps was to cover the southern sector of the front, a line of approximately from road to Puławy, through the road towards Kraków, to the line connecting Fort 18 and Fort 74. Forces under Dembiński were to defend the western and northern sector, along a line of running from Redoubt 54 to the suburb of Marymont. Most of the Polish forces were in the southern part of the city, as the Polish headquarters incorrectly assumed that the Russians would attack the weakest part of the defences, around Królikarnia, the suburbs of Mokotów and Czerniaków.
