Moritz Albrecht Franz Friedrich Fedor von Bock (3 December 1880 – 4 May 1945) was a German Generalfeldmarschall who served in the German Army during the Second World War. Bock served as the commander of Army Group North during the Invasion of Poland in 1939, commander of Army Group B during the Invasion of France in 1940, and later as the commander of Army Group Center during the attack on the Soviet Union in 1941; his final command was that of Army Group South in 1942. Bock commanded Operation Typhoon, the ultimately failed attempt to capture Moscow during the autumn and winter of 1941. The Wehrmacht offensive was slowed by stiff Soviet resistance around Mozhaisk, and also by the , the season of rain and mud in Central Russia. The Soviet counteroffensive soon drove the German army into retreat, and Bock was subsequently relieved of command by Adolf Hitler. A monarchist, Bock was not heavily involved in politics and he did not sympathize with plots to overthrow Adolf Hitler. Bock was also uncommonly outspoken, a privilege Hitler extended to him only because he had been successful in battle. Bock, his second wife and his stepdaughter were killed by a strafing Royal New Zealand Air Force fighter-bomber on 4 May 1945 as they traveled by car towards Hamburg. Fedor von Bock was born into an old Prussian military family in Cüstrin, Germany (now Kostrzyn, Poland), a fortress city on the banks of the Oder River in the Province of Brandenburg. His father, Moritz Albert Karl von Bock, had commanded a division in the Franco-Prussian War of 1870–1871. His mother, Olga Helene Franziska von Falkenhayn, was the sister of Erich von Falkenhayn, Chief of the German General Staff during the First World War. At the age of eight, Bock went to study at a military academy in Berlin. The education emphasized Prussian militarism, and he quickly became adept in academic subjects such as modern languages, mathematics, and history. He spoke fluent French, and some English and Russian.
