The Battle of Greece (also known as Operation Marita, German: Unternehmen Marita) is the common name for the invasion of Greece by Germany and Italy in April 1941. It followed a previous, unsuccessful Italian invasion known as the Greco-Italian War. It is usually distinguished from the Battle of Crete, which came after mainland Greece had been subdued. These operations were part of the greater Balkan Campaign of Germany in World War II.At the time of the German invasion, Greece was already at war with Italy, following the Italian invasion on 28 October 1940. Greece successfully defeated the initial attack and the counterattack of March 1941.
