At 2:00 that morning, a Russian train hauling grain chugged across the River Bug at Brest-Litovsk, on the German-Russian border. It was one of many that had taken the route during the past few months under Berlin-Moscow trade agreements. Seventy-five minutes later, more than 7,000 German field guns of all calibers started bombarding pinpointed targets, while overhead droned 1,000 Luftwaffe bombers on their way to pound Soviet airfields, military installations, and communications centers. A key objective was the destruction of the Red Air Force. Then, German armor and infantry surged eastward across the frontier on a 500-mile front. The onslaught would eventually cover a 2,000-mile front from the North Cape to the Black Sea.
