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.
First Battle of Nowa Wieś (1863)
After the lost Battle of Krzywosadz (February 19), General Ludwik Mieroslawski retreated to Nowa Wies, where he camped with his soldiers. In the evening of February 21, Polish insurgents were taken by surprise, when Russian forces surrounded them, and attacked. Mieroslawski’s unit was completely destroyed, also due to internal arguments between different factions in Polish camp. Most insurgents retreated towards the nearby Prussian border, and Mieroslawski himself resigned from his post as leader of the uprising.
