Battle of Warsaw

The Battle of Warsaw, also known as the Miracle on the Vistula, was a series of battles that resulted in a decisive Polish victory in 1920 during the Polish–Soviet War. Poland, on the verge of total defeat, repulsed and defeated the Red Army. After the Polish Kiev offensive, Soviet forces launched a successful counterattack in summer 1920, forcing the Polish army to retreat westward in disarray. The Polish forces seemed on the verge of disintegration and observers predicted a decisive Soviet victory. 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 Tadeusz Rozwadowski 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. The defeat crippled the Red Army; Vladimir Lenin, the Bolshevik leader, called it "an enormous defeat" for his forces. 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 1938.
