On 1 February 1944 Funck was promoted to General der Panzertruppe and appointed as the commanding general of the XXXXVII Panzer Corps, initially on the eastern and later the western fronts. During the Battle for Normandy he (who was thoroughly disliked) accused Gerhard von Schwerin of passive resistance, cowardice and incompetence over the Vire counterattack on 28 July. Less than four hours before the start of Operation Luttich, Gunther von Kluge received an order from Hitler that Heinrich Eberbach rather than Funck was to lead it, although Kluge managed to persuade OKW to postpone the transfer of command.[1]
