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)
Forces under General Martinov assaulted the central wing of Fort 56. Here the obstacles were intact, and 200 Polish soldiers repelled three consecutive assaults by a famed Moscow Guards Regiment. The Russians lost two regimental commanders before their forces managed to reach the moat. When a force of 2,900 Russians reached the top of the rampart, they were surprised by a staunch defence of a second rampart behind it. Russian infantry retreated and hid under the first rampart. Biernacki, fighting in the northern wing, managed to expel the Russian infantry, but was killed in action during the counter-attack, and the Poles withdrew back into the trees on the far side of the fort. To stabilise the situation, General Sowiński ordered a company of the 8th Line Infantry Regiment to leave the central wing and join the fight in the north. The new commanding officer of the north wing, Maj. Lipski, organised yet another counter-attack. Shouting "Mates, remember Grochów, remember Iganie!" he led his men in a charge and pushed the Russians back once again, but the impetus was lost and the Russians retained control of the rampart to the north-west. A short stalemate ensued, in which the Polish infantrymen and their single twelve-pounder carronade prevented much larger enemy forces from entering the fort.
