 Nazi Germany intervened on its ally's behalf in southern Europe.While most of the Hellenic Army was dislocated on the Albanian front to fend off the relentless Italian counter-attacks, a rapid German "Blitzkrieg" campaign commenced in April 1941, and by June (with the conquest of Crete) Greece was defeated and occupied.The Greek government went into exile, and an Axis collaborationist puppet government was established in the country.
