Günther Adolf Ferdinand von Kluge (30 October 1882 – 19 August 1944) was a German Generalfeldmarschall (Field Marshal) during World War II. Kluge held commands on the Eastern and Western Fronts, until his suicide in connection with the 20 July plot.
He commanded the 4th Army of the Wehrmacht during the invasion of Poland in 1939 and the Battle of France in 1940, earning a promotion to Generalfeldmarschall. Kluge went on to command the 4th Army in Operation Barbarossa (the invasion of the Soviet Union) and the Battle for Moscow in 1941. Amid the crisis of the Soviet counter-offensive in December 1941, Kluge was promoted to command Army Group Centre replacing Field Marshal Fedor von Bock. Several members of the German military resistance to Adolf Hitler served on his staff, including Henning von Tresckow. Kluge was aware of the plotters' activities but refused to offer his support unless Hitler was killed.
