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)
The Polish Army withdrew across the Vistula and continued north towards the Modlin Fortress. The Sejm, Senate and many civilians also left the city "in grim silence". Many soldiers, including high-ranking officers, decided to stay in the city and lay down their arms. Up to 5,000 soldiers stayed in Warsaw, along with 600 officers, among them Generals Krukowiecki, Małachowski, Chrzanowski and Prądzyński. The food stores were opened, and their contents were distributed among the civilians.
