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.
4th Cavalry Brigade (Poland)
During the Battle of Warsaw it fought in the ranks of the 4th Polish Army of Józef Piłsudski and largely contributed to the success of Piłsudski's manoeuvre that outflanked the Bolshevik forces near Warsaw. During the initial phase of the battle, the brigade fought the Battle of Cyców against the forces of Bolshevist 172nd Rifle Brigade. A successful cavalry charge broke the enemy lines and allowed the Poles to proceed with the assault. In that battle the brigade captured approximately 70 prisoners and 5 MGs.
