== Operation Barbarossa ==

June 22, 1941 marked the beginning of Operation Barbarossa. For this intricate attack, German troops were split into three divisions: Army Group North, under von Leeb; Army Group South, commanded by von Rundstedt; and Army Group Center, led by von Bock. Army Group North was destined for Leningrad, the troops under von Rundstedt in the south were to proceed through Ukraine to secure the plentiful natural resources of that country, and von Bock’s men in the Center Group were ordered through the Soviet portion of Poland to Belorussia and on to Moscow.<ref>Lyons, 107.
