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)
During the fights for the ramparts of Wola, only artillery of the second line gave limited support to the outnumbered Polish troops. Krukowiecki claimed after the war that he ordered Dembiński, Bem and General Franciszek Młokosiewicz to support the first line, but apparently none of them received the order. General Ludwik Bogusławski, commander of the 3rd Infantry Division manning the second line, could have supported the forts of the first line, but he could not see what was happening in Fort 56 due to dense smoke and the trees of Brühl's Garden.
