During the German invasion in 1941, a memorable event occurred: on April 27, as the German Army was entering Athens, the Germans ascended to the Acropolis of Athens and ordered the young Evzone who was guarding the flag post, Konstantinos Koukidis, to haul the Greek flag down and replace it with the swastika flag.
In World War II he took part in the campaigns against France, Greece, Crete and at last against Russia, when he was killed in action near Smerdyna.
After the German invasion, the occupation of Athens and the fall of Crete, King George II and his government escaped to Egypt, where they proclaimed a government-in-exile, recognised by the Western Allies, but not yet by the Soviet Union, which was temporarily friendly to Nazi Germany after the signature of the Molotov–Ribbentrop Pact.
New Zealand forces served primarily in Europe, fighting in Greece, North Africa and Italy, but with some forces serving in Singapore, Fiji, and in the Solomon Islands campaign.
