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.
