Success of Blitzkrieg
Before a potential attack, all possible information about enemy dispositions was obtained. A weak point in the enemy's defenses was identified and a powerful offensive was launched against this weak point. This offensive, known as a Schwerpunkt, comprised of massed panzers advancing under heavy fire supplied by artillery and dive-bombers. The Panzers were also supported by mechanised infantry which isolated by-passed strongpoints and defended any attacks against the German lines of communication.
