Germany, USSR, 1941: The largest military operation in human history, "Operation Barbarossa", started. Four and half million troops (with thousands of tanks and aircrafts) of the Axis powers attacked the Soviet Union. Adolf Hitler himself was the supreme commander, but the most important general was Field-Marschal Gerd von Rundstedt, who successfully directed the attacks on Poland and France. Now he took part in Operation Barbarossa as commander of Army Group South, where he led 57 divisions into the Soviet Union. Reading biography of general von Rundstedt by Earl F. Ziemke, I have found that he, who spent his childhood in an old Prussian officer’s household, has started his military schooling from age 12 (twelve)!
