1738 proved inconclusive for the Russians. Lacy once again invaded Crimea for the third time, and once again produced no lasting results. Münnich marched down the west coast of the Black Sea and crossed the Dnestr with 100,000 men, but again, disease (this time the plague), a shortage of supplies, and harassment by the Turkish screening force quickly forced him to withdraw north. To circumvent this problem, in 1739 Münnich cut even further west of the west bank of the Black Sea, skirting through Poland before arriving at the Prut. However, the situation proved to be a repeat of Peter the Great's campaign in 1711; once again the Russian's supply line was cut by encircling Turkish cavalry. Confident that he could break through this trap once he needed to, on 28 August 1737 (N.S.) he attacked the main Turkish encampment at Stavuchany. Münnich landed a diversionary blow to the Turkish right flank, then massed troops on its right and smashed through the Turks, capturing the Turkish encampment, artillery, supplies, and the Khotyn Fortress on the upper Dnestr.
