Historians still argue over whether or not a direct attack could have succeeded, but the Ukrainian diversion turned out to be a disaster for Charles. Charles's long baggage train out of Riga, along with 12,000 reinforcements, were caught by fast-moving Russian cavalry in the fall of 1708. They harassed the reinforcements and supplies, and in the ensuing Battle of Lesnaya Peter's dragoons fought the Swedes to a standstill. Facing increasing Russian numbers, the Swedes were forced to burn their supplies, bury their cannons, and make a rush for Charles's main army; out of 12,000 men, only 6,000, and virtually none of the supplies, actually made it to Charles. With more men and no supplies, this only compounded Charles's food problems. The thought-of Cossack reinforcements proved to be illusory as well; although Mazepa defected to the Swedes, he only brought 3,000 troops with him. As retribution, Menshikov sacked and razed Baturyn, slaughtering upwards of 6,000 men, women, and children and completely destroying Mazepa's capital. No one else dared defect, and Ukraine remained firmly under Peter's control.
