In the first year of the war, from September 1939 to September 1940, Germany’s military forces fought four seperate European campaigns (Poland, Scandanavia, France and the Low Countries, Britain), three of which could be described as blitzkriegBlitzkrieg Full Description A German tactical concept combining tanks, motorised infantry, artillery, and close air support in rapid offensive operations designed to penetrate enemy lines and create encirclements before the enemy could respond. Although the term was widely used during the war, it was largely a post-hoc description rather than a formal German doctrine. The fall of France in 1940 — completed in six weeks — appeared to validate blitzkrieg as a revolutionary military method, though German success also relied heavily on French strategic errors and poor command decisions. Critical Perspective Military historians have increasingly questioned whether “blitzkrieg” describes a coherent doctrine or a series of improvised successes. Karl-Heinz Frieser’s research shows that German commanders often improvised tactics on the fly in 1940, and that the Wehrmacht’s apparent invincibility was partially an artefact of Allied dysfunction. The concept became a self-fulfilling prophecy: because enemies believed it was unstoppable, they sometimes failed to resist when resistance was possible., rapid, armoured ‘lightning wars’ using aircraft and armour. The fourth campaign, the Battle of Britain, fought in the summer and autumn of 1940 was a failure, despite Lufwaffe hopes that a war could be won from the air alone. This podcast explores the us
