On 30 August 1939 (the next morning the
Wehrmacht started the
invasion of Poland), Hitler appointed Keitel to the six-person
Council of Ministers for the Defense of the Reich which was set up to operate as a "war cabinet". Nazi Germany began the
Westfeldzug on 10 May 1940 and defeated France in the
Battle of France in mid June. Keitel called Hitler "the greatest warlord of all time" and conducted the negotiations of the
French armistice. On
19 July 1940 he and eleven other generals were promoted to
Generalfeldmarschall (field marshal). The planning for
Operation Barbarossa, the 1941 invasion of the Soviet Union, was begun tentatively by Halder with the redeployment of the
18th Army into an offensive position against the Soviet Union. On 31 July 1940, Hitler held a major conference that included Keitel, Halder,
Alfred Jodl,
Erich Raeder, Brauchitsch, and
Hans Jeschonnek which further discussed the invasion. The participants did not object to the invasion. Hitler asked for war studies to be completed and
Georg Thomas was given the task of completing two studies on economic matters. The first study by Thomas detailed serious problems with fuel and rubber supplies. Keitel bluntly dismissed the problems, telling Thomas that Hitler would not want to see it. This influenced Thomas' second study which offered a glowing recommendation for the invasion based upon fabricated economic benefits. In January 1943, just before the final surrender at
Stalingrad, Hitler agreed to the creation of a three-man committee with representatives of the State, the Armed Forces High Command, and the
NSDAP in an attempt to centralize control of the war economy and over the home front. The committee members were Keitel, (Chief of OKW)
Hans Lammers (Chief of the Reich Chancellery), and
Martin Bormann (Chief of the Party Chancellery). The committee, soon known as the
Dreierausschuss (Committee of Three), met eleven times between January and August 1943. However, it had little autonomy, with Hitler reserving most of the final decisions to himself. In addition, it ran up against resistance from cabinet ministers, who headed deeply entrenched spheres of influence and, seeing it as a threat to their power, worked together to undermine it. The result was that nothing changed, and the Committee declined into irrelevance. Keitel played an important role after the failed
20 July plot in 1944. He sat on the army "
court of honour" that handed over many officers who were involved, including Field Marshal
Erwin von Witzleben, to
Roland Freisler's notorious
People's Court. Around 7,000 people were arrested, many of whom were tortured by the
Gestapo, and around 5,000 were executed. In April and May 1945, during the
Battle of Berlin, Keitel called for counterattacks to drive back the Soviet forces and relieve Berlin. However, there were insufficient German forces to carry out such counterattacks. After
Hitler's suicide on 30 April, Keitel stayed on as a member of the short-lived
Flensburg Government under
Grand Admiral Karl Dönitz. Upon arriving in Flensburg,
Albert Speer, the Minister of Armaments and War Production, said that Keitel grovelled to Dönitz in the same way as he had done to Hitler. On 7 May 1945, Alfred Jodl, on behalf of Dönitz, signed Germany's unconditional surrender on all fronts.
Joseph Stalin considered this an affront, so a second signing was arranged at the Berlin suburb of
Karlshorst on 8 May. There, Keitel signed the
German Instrument of Surrender on 8 May 1945. Five days later on 13 May, he was arrested at the request of the United States and interned at
Camp Ashcan in
Mondorf-les-Bains. Jodl succeeded him as Chief of OKW until the final dissolution of the
Flensburg Government on 23 May. ==Role in crimes of the
