Within the White Movement of the Russian Civil War of 1917-1923, Yakov Aleksandrovich Slashchov was a leading commander of Baron Wrangel's Crimean army who eventually reconciled with the Soviets and returned from Constantinople to Moscow in 1921. In 1929 he was killed in his Moscow apartment by a Jew named Lazar Kalenberg, apparently in revenge for the execution of Kalenberg's brother.
