From 21 July 1942, taking over from the court-martialed Georg Stumme,[11] to 30 September 1942, he was commanding General of the XXXX Panzer Corps, taking part in the fighting in the Caucasus. Geyr was relieved in a command cadre shakeup at the end of September 1942.[11]
In the spring of 1943 Field MarshalGerd von Rundstedt ordered Geyr to prepare a force of 10 Panzer and motorised infantry divisions. On 19 November 1943 Geyr's command was formalised as Panzer Group West, which had responsibility for the training and formation of all armoured units in the west. This group of armoured divisions near Paris constituted the Germans’ main force of tanks in France. In the event of an Allied landing on the northern French coast, Panzer Group West was expected to counterattack northward and halt the invasion force.[12]
Geyr’s reinforced tank units managed to prevent the British advance for another month, but he was nevertheless relieved of his command on 2 July, after seconding Rundstedt’s request that Hitler authorize a strategic withdrawal from Caen.[14][15][16] He was succeeded by Heinrich Eberbach on 4 July and served as Inspector General of Armoured Troops until the closing phase of the war.[12]
Post-war
Between 1945 and 1947, Geyr was in American captivity. He participated in the work of the U.S. Army Historical Division, where, under the guidance of Franz Halder, German generals wrote World War II operational studies for the U.S. Army, first as POWs and then as employees.[17][18] After his release Geyr wrote a memoir of his years in London as a military attaché, Erinnerungen eines Militärattachés, London 1933–1937 (1949), which was translated and published along with additional material covering his life through World War II as The Critical Years (1952). During the early 1950s Geyr was involved in both the development and creation of the newly built German Army (Bundeswehr) of West Germany.[19]
Geyr died in Irschenhausen near Munich. He was married to Anais Krausse (22 July 1890, Ludwigsburg - 6 November 1960, Irschenhausen).[20] Their daughter Blanche Freiin Geyr von Schweppenburg (24 March 1918 - 21 May 2003) was married to Curt-Christoph von Pfuel (2 September 1907, Berlin - 5 August 2000, Bonn), Prussian assessor, member of the Council of Europe, last Fideikommiss, Lord of Jahnsfelde.[21]
