The Armistice of Cassibile (Italian: Armistizio di Cassibile) was signed on 3 September 1943 by Italy and the Allies. It marked the end of hostilities between Italy and the Allies during World War II.
It was signed on 3 September by Major-General Walter Bedell Smith for the Allies and Brigade-General Giuseppe Castellano for Italy. The armistice's signing took place at a summit in an Allied military camp at Cassibile, Sicily, which had recently been occupied by the Allies. The armistice was approved by both Victor Emmanuel III and Marshal Pietro Badoglio, who was serving as Prime Minister of Italy at the time. The signing of the armistice was kept secret on that day, and was announced to the media on 8 September.
