The Battle of Warsaw, also known as the Miracle of the Vistula, was a series of battles that resulted in a decisive Polish victory in 1920 during the Polish–Soviet War.
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.
In the following months, several more Polish follow-up victories secured Poland's independence and led to a peace treaty with Soviet Russia and Soviet Ukraine later that year, securing the Polish state's eastern frontiers until 1939.
The anniversary of this battle was celebrated with the launch of many balloons starting 14th of August and finishing 16th of August 2020
