Warsaw 1920

The war between Poland, which has regained its independence, and Russia, which wants to export the revolution to Europe, also called the "Soviet-Polish War," has been waged since September 1919 without a formal declaration of war. Full-scale combat began in April 1920, when the Polish army launched an offensive in the south and occupied Kiev while the Russian army was extracting troops from the front to clear the remnants of the White army.
