Ivan Iskra
Ivan Ivanovych Iskra was a colonel of Poltava. Iskra belonged to the anti-Hetmanate coalition led by Vasily Kochubey. In late 1707, Kochubey and Iskra delivered a letter to the Tsar's court that accused Ivan Mazepa of initiating talks with Stanislaus Leszczynski of Poland and Charles XII of Sweden.
Peter I did not believe the letter and beheaded them both. Later when the Tsar realized that they were correct, they were reburied near the Refectory Church in Kiev Pechersk Monastery.
