Why the historical German victory was fragile

Repeated command changes left British and Commonwealth units confused and poorly coordinated after the Greek campaign. The episode foreshadows Malaya: individual formations fought well while the higher command failed to turn their performance into a coherent defence. Part of the disruption came from Winston Churchill's repeated search for a commander of sufficient seniority. Yet the Allies had roughly 38,000 to 39,000 troops against about 15,000 German airborne and mountain troops reaching the island, alongside active Cretan resistance. About 10,000 Greek troops also offered the nucleus of a substantial local garrison. Prepared positions and an established Greek staff could therefore remove much of the uncertainty that made the historical attack succeed.
