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 (1705)
In 1705 Stanisław Leszczyński was due to be crowned in Warsaw, after which peace negotiations between Sweden and Poland could take place. The Swedes were eager to increase support for Leszczyński to strengthen their position in the Polish–Lithuanian Commonwealth. The coalition forces, under Peter I of Russia and Augustus II, would not sit idle, and planned a grand strategy of their own, mainly based upon the ideas of Johann Patkul and Otto Arnold von Paykull; they would gather all available forces and crush the Swedish Army in Poland–Lithuania by a joint offensive.
