In 1938, he organised an amphibious combined operations landing exercise that impressed the new C-in-C of Southern Command, General Sir Archibald Percival Wavell. He was promoted to major general on 14 October 1938 and took command of the 8th Infantry Division in the British mandate of Palestine. In Palestine, Montgomery was involved in suppressing an Arab revolt which had broken out over opposition to Jewish emigration. He returned in July 1939 to Britain, suffering a serious illness on the way, to command the 3rd (Iron) Infantry Division. Reporting the suppression of the revolt in April 1939, Montgomery wrote, "I shall be sorry to leave Palestine in many ways, as I have enjoyed the war out here".
