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.

By that point the battle plan of the Russians was still not clear to the Polish Commander-in-Chief General Krukowiecki. Unsure whether the main attack was on Wola or the forts around Królikarnia, he did not reassign any sizable infantry force to the western front, despite the fact that the southern line was safely in Polish hands and repeated Russian attacks there were being repelled one by one. Out of 3,000 casualties suffered by the Polish side on the first day only approximately 300 were in the southern sector near Królikarnia, including at most "several dozen killed". Yet only a small detachment of horse artillery was dispatched to the second line near Wola. In the evening General Krukowiecki called a meeting of the government and described the situation of his forces as extremely difficult. He suggested that talks with Paskevich be resumed and sent General Prądzyński to Paskevich's camp.
