The Battle of Warsaw (Polish: Bitwa Warszawska; Russian: Варшавская битва, Varshavskaya bitva), also known as the Miracle on the Vistula (Polish: Cud nad Wisłą), was a series of battles that resulted in a decisive Polish victory and complete disintegration of the Red Army in August 1920 during the Polish–Soviet War. After the Polish Kiev offensive, Soviet forces launched a successful counterattack in summer 1920, forcing the Polish army to retreat westward. The Polish forces seemed on the verge of disintegration and observers predicted a decisive Soviet victory. The Battle of Warsaw was fought from August 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.
