Johannes Blaskowitz:
"As a traditional soldier, Blaskowitz kept a firm control on the men under his command in their dealings with civilians, and was outraged by the atrocities committed by the SS and the Einsatzgruppen against Polish and Jewish people. Between November 1939 and February 1940 he wrote several memoranda to higher command, in which he detailed SS atrocities in Poland, their effects on Wehrmacht soldiers, and the insolent attitude of the SS to the army.
"However, his protests produced no condemnations of such behavior, and merely earned him the enmity of Hans Frank, Reinhard Heydrich, Heinrich Himmler, and Adolf Hitler, while Chief of Staff Alfred Jodl dismissed them as naive and "uncalled for".[1]
"Commander-in-Chief Walther von Brauchitsch forwarded Blaskowitz's first memorandum to Hitler on 18 November, who launched a tirade against Blaskowitz, denouncing his concerns about due process as "childish" and poured scorn on his "Salvation Army attitude".[2] As a result, Blaskowitz found himself placed on a blacklist, and he was relieved of his command on 29 May 1940."
Walter von Reichenau:
"During the invasion of the Soviet Union in June 1941, von Reichenau again commanded the 6th Army, which captured Kiev and Kharkov.
"Politically, von Reichenau was an active anti-Semite and supported the work of the SS Einsatzgruppen in exterminating the Jews in the occupied Soviet territories. He encouraged his soldiers to commit atrocities against the Jews, telling them: "...In this eastern theatre, the soldier is not only a man fighting in accordance with the rules of the art of war...For this reason the soldier must learn fully to appreciate the necessity for the severe but just retribution that must be meted out to the subhuman species of Jewry...".
"During the offensive, Reichenau inspected every single Russian tank he came across. He would enter each tank and, using a ruler, he would examine the thickness of the armor. Upon examining a T-34 Tank, he told his officers, "If the Russians ever produce this tank on an assembly line, we will have lost the war."
..."In January 1942 von Reichenau suffered a cerebral hemorrhage... von Reichenau actually died of a heart attack."
Gunther von Kluge:
"When Stauffenberg attempted to assassinate Hitler on July 20, Kluge was Oberbefehlshaber West ("Supreme Field Commander West") with his headquarters in La Roche-Guyon. The commander of the occupation troops of France, General Karl-Heinrich von Stülpnagel, and his colleague Colonel Cäsar von Hofacker - a cousin of Stauffenberg - came to visit Kluge. Stülpnagel had just ordered the arrest of the SS units in Paris.
"Kluge had already learned that Hitler had survived the assassination attempt and refused to provide any support. "Ja - wenn das Schwein tot wäre!" ("Well - if the pig were dead!)" he said. [4]
"He was recalled to Berlin for a meeting with Hitler after the coup failed; thinking that Hitler would punish him as a conspirator, he committed suicide by taking cyanide near the World War I battlefield at Verdun. He left Hitler a letter in which he advised Hitler to make peace and “put an end to a hopeless struggle when necessary...”
"Hitler reportedly handed the letter to Alfred Jodl and commented that “There are strong reasons to suspect that had not Kluge committed suicide he would have been arrested anyway.” "
