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)
General Prądzyński was once again dispatched to the Russian headquarters, where he was greeted by Grand Duke Michael Pavlovich as Paskevich had been wounded shortly before. Although Michael believed the Poles were playing for time to allow Ramorino's Corps to return from Podlasie, Prądzyński convinced him to send General Berg to Warsaw with a draft of an act of unconditional surrender. The agreement (apparently never signed on paper) stipulated that the Polish Army was free to leave the city, a two-day cease-fire would come into effect and that Warsaw would be spared the horrors it experienced during the 1794 siege. No political clauses were included. Around 17:00 Prądzyński and Berg arrived in Warsaw, where Krukowiecki generally agreed with the Russian terms, but considered them too harsh. Berg and Prądzyński then returned to Russian headquarters and Grand Duke Michael agreed to allow the Polish Army free passage to Modlin and Płock, an amnesty to all fighters of the Uprising, and to exchange prisoners. The new terms were more than acceptable to Krukowiecki. Upon Prądzyński's return the more liberal wing of the government won a temporary majority, and Krukowiecki was ousted from power and replaced with Bonawentura Niemojowski as head of government and General Kazimierz Małachowski as Commander-in-Chief.
