The Battle of Krasnystaw was fought around the city of Krasnystaw by the Polish 39th Infantry Division and the Cavalry Brigade of Colonel Adam Zakrzewski of the Northern Front under Stefan Dąb-Biernacki against German forces. In the battle the Northern front seeked to recapture Krasnystaw from the German 4th Infantry Division as they there were blocking their southwards advance to come to the aid of Lublin Army and Kraków Army fighting at the Battle of Tomaszów Lubelski. Polish forces were unable to capture Krasnystaw in the battle and this delayed them meeting up with Lublin army and Kraków army.
