Mykhailo Krychevsky

Mykhailo Krychevsky or Stanisław Krzyczewski or Krzeczowski (died 3 August 1649) was a Polish noble, military officer and Cossack commander. He fought for the Polish–Lithuanian Commonwealth against various Cossack revolts and Crimean Tatar factions. During his time as a Cossack commander, Krychevsky befriended Bohdan Khmelnytsky, who would go on to stage a revolt against the Polish-Lithuanian throne.

After being captured by enemy forces in 1648, Krychevsky was ransomed to Khmelnytsky and was named an acting hetman of Khmelnytsky's rebel forces. Krychevsky was mortally wounded in the battle of Loyew on 31 July 1649 and died in the custody of Polish forces.
