Question: Which  Chief of the German General Staff was sacked on on 28 August 1916
Context: Matvei Vasilevich Zakharov (Russian: Матве́й Васи́льевич Заха́ров , August 17, 1898 – January 31, 1972), Marshal of the Soviet Union, Chief of the General Staff, Deputy Defense Minister, was born in Voylovo, a village in Kalininsky District, Tver Oblast to peasant parents.  Zakharov joined the Red Guards (precursor to the Red Army) in 1917.  He served under Kliment Voroshilov during the Russian Civil War.  Zakharov graduated from the Frunze Military Academy in 1928, and from Soviet General Staff Academy in 1937 (his graduation was actually a year ahead of schedule, due to the lack of officers in the Red Army because of the explosive growth of the army, as well as Stalin's purges.)  Zakharov held a number of high-ranking positions before World War II even began.  In 1937 he was made the Chief of Staff of the Leningrad Military District, then in 1938–1940 he was the Deputy Chief of the General Staff, and then the Chief of Staff of the Odessa Military District. The Army Group Rupprecht of Bavaria or Army Group A (German: "Heeresgruppe Kronprinz Rupprecht von Bayern") was an Army Group of the German Army, which operated on the Western Front under command of Rupprecht, Crown Prince of Bavaria , between 28 August 1916 and 11 November 1918 during World War I.  It was formed from the short-lived Army Group Gallwitz under Max von Gallwitz (19 July - 28 August 1916). The Hindenburg Programme of August 1916 is the name given to the armaments and economic policy begun in late 1916 by the Third "Oberste Heeresleitung" ("OHL", the German General Staff), Field Marshal Paul von Hindenburg and General Erich Ludendorff.  The two were appointed after the sacking of General Erich von Falkenhayn on 28 August 1916 and intended to double German industrial production, greatly to increase the output of munitions and weapons. The General Staff of the Armed Forces of the Republic of Belarus is the central body of military management and operational control of the Armed Forces of Belarus.  The Chief of the General Staff is appointed by the President of Belarus, who is the Supreme Commander-in-Chief of the Armed Forces.  The current Chief of the General Staff is Major General Oleg Belokonev.  The General Staff is part of the Ministry of Defense of Belarus. General Staff (Vietnamese: "Bộ Tổng tham mưu" ) is the commanding and managing organisation of the Vietnam People's Army, the paramilitary forces, militia and other activities relating to defence of Vietnam.  The General Staff was established on 7 September 1945, right after the foundation of the Democratic Republic of Vietnam, the first Chief of the General Staff was General Hoàng Văn Thái.  During the Second Indochina War, Vietnam War, Cambodian-Vietnamese War, Sino-Vietnamese War and other skirmishes, the General Staff always had an essential role in organising, commanding the armed forces and planning, operating military campaigns for the Ministry of Defence and the Government of Vietnam.  The current Chief of the General Staff is Senior Lieutenant General (AKA Colonel General) Phan Văn Giang who also holds the position of Deputy Minister of Defence. The German General Staff, originally the Prussian General Staff and officially Great General Staff ("Großer Generalstab"), was a full-time body at the head of the Prussian Army and later, the German Army, responsible for the continuous study of all aspects of war, and for drawing up and reviewing plans for mobilization or campaign.  It existed unofficially from 1806, and was formally established by law in 1814, the first general staff in existence.  It was distinguished by the formal selection of its officers by intelligence and proven merit rather than patronage or wealth, and by the exhaustive and rigorously structured training which its staff officers undertook.  Its rise and development gave the German armed forces a decisive strategic advantage over their adversaries for nearly a century and a half. Franz Halder (30 June 1884 – 2 April 1972) was a German general and the chief of the "Oberkommando des Heeres" staff (OKH, Army High Command) from 1938 until September 1942, when he was dismissed after frequent disagreements with Adolf Hitler.  Until December 1941 Halder's military position corresponded to the old Chief of the General Staff position, which during World War I had been the highest military office in the German Imperial Army.  Halder's diary during his time as chief of OKH General Staff has been a source for authors that have written about such subjects as Hitler, World War II and the Nazi Party.  In William Shirer's "The Rise and Fall of the Third Reich", Halder's diary is cited hundreds of times. Ludwig August Theodor Beck (29 June 1880 – 21 July 1944) was a German general and Chief of the German General Staff during the early years of the Nazi regime in Germany before World War II.  Ludwig Beck was never a member of the Nazi Party, though in the early 1930s he supported Adolf Hitler's forceful denunciation of the Versailles Treaty and belief in the need for Germany to rearm.  Beck had grave misgivings regarding the Nazi demand that all German officers swear an oath of fealty to the person of Hitler in 1934, though he believed that Germany needed strong government and that Hitler could successfully provide this so long as he was influenced by traditional elements within the military rather than the SA and SS. The Chief of the General Staff (Ukrainian: Начальник Генерального штабу ) is the chief of staff of the General Staff of the Ukrainian Armed Forces.  He/she is appointed by the President of Ukraine.  If the Minister of Defense is a civilian the Chief of the General Staff becomes the commander-in-chief of the Ukrainian Armed Forces.  The current Chief of the General Staff is Viktor Muzhenko. General Erich Georg Anton von Falkenhayn (11 September 1861 – 8 April 1922) was the Chief of the German General Staff during the First World War from September 1914 until 29 August 1916.  He was removed in the late summer of 1916 after the failure at the battle of Verdun, the opening of the Allied offensive on the Somme, the Brusilov Offensive and the entry of Romania into the war.  He was later given important field commands in Romania and Syria.  His reputation as a war leader was attacked in Germany during and after the war, especially by the faction which supported Hindenburg.  Falkenhayn held that Germany could not win the war by a decisive battle but would have to reach a compromise peace; his enemies said he lacked the resolve necessary to win a decisive victory.  Falkenhayn's relations with the Chancellor Bethmann-Hollweg were troubled and undercut Falkenhayn's plans.
Answer: Erich von Falkenhayn
