On 7 April 1340, Prince Yuri II Boleslav of Galicia-Volhynia was poisoned by boyars. He died heirless and had bequeathed his duchy to Casimir the Great of Poland. Casimir launched rapid military expeditions into Ruthenia, but Ruthenian boyars opposed to Polish incorporation allied with Tatar forces and invaded Polish lands under the leadership of boyar opposition leader Dmytro Dedko.
In January 1341, the combined Tatar cavalry and Ruthenian forces under Dmytro Dedko clashed with the Polish army at the Vistula River. The Polish knights successfully defended the river line, preventing the invaders from crossing. During the fighting, Sandomierz voivode Mikołaj Czelej was killed by a Tatar arrow, as recorded by chronicler Jan of Czarnków.
The Tatar-Ruthenian forces were repulsed and retreated toward Lublin, ending their immediate incursion into Polish territory. The battle was part of the broader, prolonged struggle for control of the Kingdom of Galicia-Volhynia, in which Casimir the Great would continue to contest Ruthenian lands against both local boyars and Tatar interference.
