Soviet forces gathered 166 divisions on the Belorussian front, and attacked along a 450-mile expanse. The attack was so swift that the Red Army sometimes advanced as much as 15 miles a day. Although caught by surprise, the Germans still exacted a terrible price as Soviet forces suffered nearly 750,00 casualties during the two-month-long operation. But Operation Bagration was soon seen as the death knell of Nazi Germany.
