The Battle of Zieleńce was a battle in the Polish–Russian War of 1792, in defence of the Polish Constitution of 3 May 1791. The battle took place on 18 June 1792, between the Polish–Lithuanian Commonwealth Army of Józef Poniatowski and an Imperial Russian Army group under the command of General Irakly Morkov, which was a part of General Mikhail Krechetnikov's Russian forces invading the Polish–Lithuanian Commonwealth from the south. The battle ended in Polish victory, as the Russian assault was repulsed, although the Poles soon withdrew from the battlefield. Prelude Polish forces had been retreating for several weeks, avoiding a decisive engagement with the numerically superior Russian forces. On 15 June, the joined Polish forces reached Połonne. After a meeting, the Polish commanders decided to withdraw because they did not have the possibility of defending a town that did not have fortifications. On 17 June, Polish commander Prince Józef Poniatowski received information in Szepietówka that the Lubomirski division was now camped in Zasław. He ordered the Lubomirski division to join his forces near Zieleńce. Lubomirski had about 2,000 infantry and 1,000 cavalry, including units of general Józef Zajączek and Ludwik Trokin. His formation secured a hill situated on the north of the road from Połonne to Zasław which dominated the area. Infantry taking position in centre wings were secured by cavalry. In the early morning of 18 June, a Russian group under command of General Irakly Morkov was observed. This group was front watch of larger corps of General Mikhail Golenishchev-Kutuzov. The order of this group was to attack the Polish army left wing and destroy the rest of train. With a force about 10,500.-11,500s soldiers and 24 cannons (2 infantry regiments of about 6,000 soldiers, three regiments of line cavalry of 2,500 soldiers, and a Cossack brigade under command of Orlov), the Russian formations took positions in a valley below a hill. Their order of battle was the same as Polish, except that one battalion was a reserve and the second to secure the train. Meanwhile, General Zajączek contacted Poniatowski for help.
