October 28 is a National holiday in Greece celebrating the Οxi (No) Day – the refusal of General Metaxas, prime minister of Greece in 1940, to accept the Italian ultimatum in WW2. It also celebrates the following successful military campaign of Greece, which eventually ended with the Greek victory over the invading Italian army. The Greek victory changed the course of World War II because it was first Allied victory in World War II and because it forced Hitler to divert some of his forces to aid Italy in April 1941 – delaying the German attack against Russia to wintertime.
