The Germans invaded Crete on May 20th 1941. Its geographical importance in both German and Allied planning for the domination of the Mediterranean and Africa was to prove Crete's downfall. As the Germans mounted 'Operation Mercury' a ragbag collection of defenders readied themselves for the onslaught. Nazi intelligence had assured the attacking force that their presence on the island would be welcomed by the presumed docile inhabitants. The local Cretans, along with an eclectic mix of Allied troops, would prove that intelligence flawed. This episode tells the story of the mistakes and miscalculations made by both the British and German armies as they fought for control of the Island and how the 'mountain men' of Crete played a crucial role in the allied fight back. With the island captured in bloody fighting by the Germans, the skillful native fighters of Crete would prove a significant thorn in the side of the occupying German army.
