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.
Siege of Zbarazh
The Polish-Lithuanian forces were commanded officially by Andrzej Firlej. However, as noted by Polish historian Widacki, Firlej had little authority, and often listened to Wiśniowiecki's advice, who could be seen as the real commander of the Polish-Lithuanian forces. As a contemporary memoir notes, Wiśniowiecki's position was enough to veto a plan proposed and backed by all three regimentarzs. Each of the regimentarz, as well as prince Wiśniowiecki, commanded a division of the troops, tasked with defending a part of the line; there were five divisions in total, with the last one commanded by chorąży Aleksander Koniecpolski.
