After the German army defeated Poland, Denmark, and France, a still-jealous Mussolini decided to use Albania as a springboard to invade Greece. The Italians launched their attack on October 28, 1940, and at a meeting of the two fascist dictators in Florence, Mussolini stunned Hitler with his announcement of the Italian invasion. Mussolini counted on a quick victory, but Greek resistance fighters halted the Italian army in its tracks and soon advanced into Albania. The Greeks took Korçë and Gjirokastër and threatened to drive the Italians from the port city of Vlorë. The presence of the Greek troops fighting in Albania cooled the Albanians' enthusiasm for fighting the Italians and the Greeks, and Mussolini's forces soon established a stable front in central Albania. In April 1941, Germany and its allies crushed both Greece and Yugoslavia, and a month later the Axis gave Albania control of Kosovo. Thus Albanian nationalists ironically witnessed the realization of their dreams of uniting most of the Albanian-populated lands during the Axis occupation of their country.
