クリコヴォの戦い
St. Sergius supported Dmitri Donskoi in his struggle against the Tatars and sent two of his monks, Peresvet and Oslyabya, to participate in the Battle of Kulikovo (1380). At the outbreak of the battle, Peresvet died in a single combat against a Tatar bogatyr. The monastery was devastated by fire, when a Tatar unit raided the area in 1408.
