クン・ベーラ
In the Crimea, Béla Kun and Rosalia Zemlyachka, with Vladimir Lenin's approval, had 50,000 White prisoners of war and civilians summarily executed by shooting or hanging after the defeat of general Pyotr Wrangel at the end of 1920. They had been promised amnesty if they would surrender. This is one of the largest massacres in the Civil War.
