“Non-motorised infantry divisions are only of value against a motorised and armoured enemy when occupying prepared positions.
If these positions are pierced or outflanked, a withdrawal will leave them helpless victims of the motorised enemy, with nothing else to do but hold on in their positions to the last round.” (Rommel, 1953, p198).
Field-Marshal Erwin Rommel (the Desert Fox), World War I junior officer and World War II General, considered a brilliant military commander; adored by his troops and feared by his enemies.
