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.
History of Poland (1939–1945)
The Bug River was crossed by the Soviets (1st Belorussian Front) on 19 July 1944 and their commander Konstantin Rokossovsky headed for Warsaw, together with the allied Polish forces. As they approached the Polish capital, German panzer divisions counterattacked, while the Poles commenced the Warsaw Uprising. After the German attack was brought under control, Rokossovsky informed Stalin on 8 August that his forces would be ready to engage in an offensive against the Germans in Warsaw around 25 August, but received no reply. The Soviets secured their Vistula bridgeheads, and, with the First Polish Army, established control over the Praga east-bank districts of Warsaw. The situation on the ground, combined with political and strategic considerations, resulted in the Soviet decision to pause at the Vistula for the remainder of 1944.
