ミハイル・トゥハチェフスキー
Found guilty, Dumenko and three others were shot on 11 or 13 May 1920. The background of this execution is the conflict between Trotsky and Stalin. Dumenko was a supporter of Joseph Stalin, his successor Mikhail Tukhachevsky a nominee of Leon Trotsky. Dumenko had been highly critical on the policy of Lev Trotsky of having political commissaries control the Army commanders from the rearguard and not in combat.
