The Corps was formed in Palestine in August 1917 under the command of Lieutenant General Edward Bulfin.^[1] It formed part of the Egyptian Expeditionary Force (EEF) and served in the Sinai and Palestine Campaign. At the Battle of Sharon it fought what has been described as 'one of the most overwhelmingly successful operations of the war'^[2] and 'a precursor to the modern Blitzkrieg.'^[3] It then carried out remarkable march up the coast of modern-day Lebanon as the war came to an end.
