Joachim Lemelsen (28 September 1888 – 30 March 1954) was a German general during World War II who rose to army-level command. During Operation Barbarossa, the invasion of the Soviet Union in 1941, troops of the XLVII Motorized Corps under his command executed the criminal Commissar Order, prompting Lemelsen to complain: "Soon the Russians will get to hear about the countless corpses lying along the routes taken by our soldiers (...). The result will be that the enemy will hide in the woods and fields and continue to fight--and we shall lose countless comrades".
