In the early hours of October 28, 1940, Mussolini sent an ultimatum to Greece through the ambassador in Athens, Emanuele Grazzi, who delivered it directly to Ioannis Metaxas. The Italians aimed to gain control over strategic locations, such as ports and airports in Greece, without resistance.
Upon receiving the ultimatum, Metaxas responded negatively to the Italian ambassador in French: “Alors, c’est la guerre” (So, this means war). This response became known in history as the “NO.”
The Greco-Italian War of 1940-41, or the Epic of ’40, lasted from October 28, 1940, until June 1, 1941, when German forces completed their occupation of the country.
