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.
Lack of outside support during the Warsaw Uprising
In the Praga area Polish units under command of General Zygmunt Berling (thus sometimes known as 'berlingowcy' - 'the Berling men'), the 1st Polish Army ("1 Armia Wojska Polskiego") were in position. On the night of September 14/September 15 three patrols from landed on the shore of Czerniaków and Powiśle areas and made contacts with Home Army forces. Under heavy German fire only small elements of main units made it ashore (I and III battalions of 9th infantry regiment, 3rd Infantry Division). At the same time the commanders of the Red Army declined to support the Polish troops with artillery, tanks or bombers.
