During the Russo-Turkish War (1735–1739), the Russian field marshal Burkhard Christoph von Munnich successfully stormed the fortifications on June 17, 1736, and left the Tatar fortress in ruins. In 1738, it was taken again by Russian General Lacy. This was a serious, if not mortal, blow to the independence of the Crimean Khanate. In 1754, it was rebuilt by Qirim Giray. In 1771, the fortress was captured decisively by Russian General Dolgorukov.
