World War II Headlines
Below are more images and highlights from World War II detailing the Nazi German campaign of 1941.
German Wehrmacht overwhelms Red Army in Russia: When Operation Barbarossa began, three separate German army groups -- comprised of tanks, trucks, motorcycle troops, foot soldiers, and several hundred thousand horses -- raced into Russia, attacking in the north, south, and central areas. They surrounded and captured masses of Red Army soldiers. Wehrmacht general Blumentritt described "great clouds of yellow dust kicked up by the Russian columns attempting to retreat and by our infantry hastening in pursuit." However, the general also commented, "The infantry had a hard time keeping up." A march of 25 miles a day was not unusual, and when panzers encountered rough or wooded terrain and superior Russian tanks, they had to stop and wait for the infantry to catch up to help clear the route.
