The action of (the) Tyniec Abbey was an engagement between the armies of the Russian Empire and the Bar Confederation that took place on 20 May 1771. Russian Major-General Suvorov, in co-operation with Lieutenant-Colonel Shepelev's cavalry, assaulted Lieutenant-Colonel Dumouriez's army on a mountain redoubt fortified with a palisade, trous de loup, and two cannons; near the Tyniec Abbey, the village of Tyniec; but after taking the redoubt twice, they were twice repulsed, however, managed to capture all the cannons; Suvorov refused to retake the redoubt, and withdrew to meet Dumouriez, who had meanwhile brought reinforcements, in the third confrontation at Lanckorona. Almost all the infantry of the Tyniec consisted of Austrian deserters.
