The Battle of Kostiuchnówka was a World War I battle that took place July 4–7, 1916, near the village of Kostiuchnówka (Kostyukhnivka) and the Styr River in the Volhynia region of modern Ukraine, then part of the Russian Empire. It was a major clash between the Russian Army and the Polish Legions (part of the Austro-Hungarian Army) during the opening phase of the Brusilov Offensive. Polish forces, numbering 5,500–7,300, faced Russian forces numbering over half of the 46th Army Corps of 26,000. The Polish forces were eventually forced to retreat, but delayed the Russians long enough for the other Austro-Hungarian units in the area to retreat in an organized manner. Polish casualties were approximately 2,000 fatalities and wounded. The battle is considered one of the largest and most vicious of those involving the Polish Legions in World War I.
