September Storm The German Invasion of Poland

The German Blitzkrieg doctrine called for multiple deep penetrations by Panzer and other mobile forces to thrust into the enemy rear areas to destroy combat forces in their path, artillery positions, headquarters, and rear service organizations. Flanks were frequently ignored with emphasis on striking deep and disrupting the enemys defensive plan, command and control, and lines of communications. Frontline enemy forces would be splinted and often separated into pockets cutoff from retreat or reinforcement to be dealt with by follow-on infantry forces. Other infantry forces would hold by-passed enemy frontline forces in-place with limited attacks.
