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)
Despite the loss of forts 54, 55 and 57, Krukowiecki was still convinced that the attack on Wola was a diversion, and refused to grant General Dembiński more reinforcements. Only General Ludwik Bogusławski, commanding officer of the 3rd Infantry Division, disregarded his orders and sent a single battalion of the 10th Line Infantry Regiment to Fort 56 as reinforcements. The battalion was led by Col. Piotr Wysocki, the officer who started the entire November Uprising. Dembiński abandoned Fort 58. Its artillery, along with 12 cannons and six rocket launchers from his reserves, was ordered to take positions between the first and second lines of defence, in front of Forts 21, 22 and 23. Around 9:00, when Russian forces were preparing to push further into the second line of Polish defences, Brigadier Józef Bem arrived to Wola with his 12 cannon and positioned them not far from the recently-lost Fort 54, right on the flank of Kreutz's infantry and Russian artillery shelling Fort 56. Eight more guns and four rocket launchers arrived to the northern flank of Wola and joined the defence of Fort 58. Around that time the combined artillery forces of both Russian infantry corps shifted their fire to Forts 56, 59 and 23. This time the Poles won the artillery duel. Despite Russian numerical superiority in guns and mortars, the Russian artillery suffered losses and was forced to withdraw, followed by infantry, likewise forced back into hiding behind the captured earthworks. Dembiński did not take advantage of this success, and the Polish infantry remained hidden behind fixed defences.
