Walter Bedell Smith in the context of "Armistice of Cassibile"

Supreme Headquarters Allied Expeditionary Force (SHAEF; /ˈʃeɪf/ SHAYF) was the headquarters of the Supreme Commander, Allied Expeditionary Force (SCAEF), in northwest Europe, from late 1943 until the end of World War II. US General Dwight D. Eisenhower was the commander in SHAEF throughout its existence. The position itself shares a common lineage with Supreme Allied Commander Europe and Atlantic, but they are different titles.

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.
