Early in World War II, the German Blitzkrieg appeared to smash through all resistance, but were these tactics really as devastating as they seemed? In 1941, the Germans overran Greece in three weeks, yet never managed to gain ascendancy over the token British and Anzac force sent to bolster the Greek army. As Jeffrey Plowman points out here, the Blitzkrieg had reached its strategic limit, and Greece's defenders found ways of repelling and redirecting Germany's aggressive attacks.
