The Battle of the Four Rivers (Russian: Сражение на четырех реках) or Battles on the Bzura, Rawka, Pilica and Nida was one of the key battles in 1914, as a result of which the Germans tried to break through and take Warsaw, but they could not do it. The battle was the first positional battle on the eastern front, and is also one of the bloodiest battles in 1914.
