The Battle of Radzymin (Polish: Bitwa pod Radzyminem) took place during the Polish–Soviet War (1919–21). The battle occurred near the town of Radzymin, some 20 kilometres (12 mi) north-east of Warsaw, between August 13 and 16, 1920. Along with the Battle of Ossów and the Polish counteroffensive from the Wieprz River area, this engagement was a key part of what later became known as the Battle of Warsaw. It also proved to be one of the bloodiest and most intense battles of the Polish–Soviet War. The first phase of the battle began on August 13 with a frontal assault by the Red Army on the Praga bridgehead. The Russian forces captured Radzymin on August 14 and breached the lines of the 1st Polish Army, which was defending Warsaw from the east. Radzymin changed hands several times in heavy combat. Foreign diplomats, with the exception of the British and Vatican ambassadors, hastily left Warsaw. The plan for the battle was straightforward for both sides.
