why was the blitzkrieg effective
During the interwar period, aircraft and tank technologies matured and were combined with systematic application of the German tactics of infiltration and bypassing of enemy strong points. When Germany invaded Poland in 1939, Western journalists adopted the term blitzkrieg to describe this form of armoured warfare. Blitzkrieg operations were very effective during the campaigns of 1939â1941. These operations were dependent on surprise penetrations (e.g. the penetration of the Ardennes forest region), general enemy unpreparedness and an inability to react swiftly enough to the attacker's offensive operations.
