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)
Paskevich held a war council with his generals. Karl Wilhelm von Toll and many other generals insisted that the assault on Wola be resumed, but Paskevich was sceptical. The Russians still had 25,000 fresh troops, but the dusk was nearing, and Paskevich feared that after dark his forces might lose cohesion and suffer excessive losses. The Russian commander also thought that an attack on Wola might be hampered by positions of the first line still held by the Poles (Forts 58, 59 and 60; in reality Fort 58 had been abandoned), or by a Polish counter-attack from the area of Czyste. He decided to postpone offensive actions until the following day. Paskevich also sent another envoy to Warsaw, but the hastily called session of the Sejm renounced his offer of a cease-fire.
