" The Battle of Konotop, fought near the present-day Russo-Ukrainian border in June 1659, ended in a spectacular victory for Vyhovsky. The Muscovite army, approximately 70,000 strong, was defeated, up to 15,000 soldiers were killed, and the flower of the Muscovite cavalry was annihilated. The Tatars moved on, pillaging the southern borderlands of Muscovy. Rumors filled Moscow that the tsar was about to leave the capital. "
