The siege was put under the command of Adjutant General Menshikov, with total forces of 23,000 personnel and 170 artillery pieces against the 20,000 garrison of Varna. When Menshikov being wounded the siege was entrusted to General Field Marshal Mikhail Semyonovich Vorontsov.
In an attempt to desiege Varna, Omer Vryonis Pasha brought an army of 20,000, but was successfully held off. At the battle of Kurtepe the Russians under prince Eugene attacked but they were defeated and retreated. However the Turks did not follow up this victory and waited 11 days at the place. In the meantime Varna capitulated. Eventually Varna was taken with 6,900 prisoners and 140 artillery pieces. The town was surrendered by Yusuf Pasha.
