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.
Konstanty Plisowski
During the Polish Defensive War of 1939 Plisowski found himself in Brześć, where he volunteered for the army. He was made the commander of the Brześć Fortress and managed to organise resistance against the advancing German XIX Panzer Corps of general Heinz Guderian. After the unconcluded Battle of Brześć, in which his four infantry battalions managed to halt the advance of four German divisions for four days, Plisowski retreated with his men and joined the forces of general Franciszek Kleeberg. He was assigned to the Cavalry Operational Group of general Władysław Anders as his deputy. On 24 September he was made the commanding officer of the Nowogródzka Cavalry Brigade, with which he fought both against Nazi Germany and the Soviet Union.
