The naval bombardment and occupation of the Greek island of Corfu by Italian troops. An Italian general and four members of his staff, engaged under international authority in determining the boundary between Greece and Albania, had been murdered three days before. Following the bombardment by Italy in which 16 people were killed, Mussolini issued an ultimatum, demanding a heavy indemnity. Greece appealed to the League of Nations, which referred the dispute to the Council of Ambassadors. The Council ordered Greece to pay 50 million lire. Under pressure from Britain and France, Italian troops withdrew. The outcome of the dispute raised serious doubts about the strength and efficiency of the League.
