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)
Seeing that their forces had failed, Paskevich and Pahlen decided to throw in even more forces into the fight. Elements of the 9th 'Ingermanland' Infantry Regiment and 10th 'New Ingermanland' Infantry Regiment (890 men and six guns) were ordered to attack the eastern side of the northern wing. Simultaneously seven battalions (ca. 4,000 men) were to attack the central and eastern wings from the south. About 70 pieces of artillery were ordered to fire on the second line of Polish defences to prevent Polish reinforcements from breaking through to the fort. This time several thousand Russians entered the northern wing in strict military formations. By then the garrison under Maj. Lipski had 800 men and was not strong enough to withstand the assault. Poles were again pushed back into the trees of the far side of the northern wing, and Maj. Lipski was killed. He was replaced by Maj. Dobrogoyski, who panicked and sounded a retreat, taking with him 500 men. The remaining 300 soldiers under Maj. Świtkowski tried again to force the Russians out, but were by then outnumbered 10 to 1 and around 10:30 had to withdraw towards the central wing. The central wing, by then under the command of Lt. Col. Wodzyński, held out against a large column led by General Lüders, composed of the elite regiments of Prince Wilhelm and Prince Charles.
