The Oxi (No) Day on Crete.
October 28th is a national holiday throughout Greece and at the same time the annual tourist season comes to an end.
On 28 October 1940 the Greek dictator Metaxas rejected Mussolini’s ultimatum with a short Oxi (No), after which the Italian army attacked Greece from Albania.
This soon ended in a severe Italian defeat and forced Hitler to go on the Balkans campaign half a year later.
