Order of battle for the Battle of Megiddo (1918)

This is the order of battle for the Battle of Megiddo (1918), the concluding engagement of the Sinai and Palestine Campaign of the First World War. The Entente's Egyptian Expeditionary Force, commanded by General Edmund Allenby and composed mainly of British, Indian, Australian and New Zealand troops, with a small French and Armenian contingent, cooperated with the Arab Northern Army, which was part of the Arab Revolt and was under the overall command of the Emir Feisal, in an all-out offensive against the Yıldırım Army Group, part of the army of the Ottoman Empire.

After preliminary attacks beginning late on 16 September 1918, Allenby's main attack overran the Ottoman front lines on 19 September. British Indian Army and Australian mounted divisions seized objectives far behind the front line, while British and Australian aircraft crippled the Ottoman armies' headquarters and attacked retreating Ottoman troops, turning their retreat into a rout.

Most of the Ottoman formations were destroyed by 26 September. Allenby's mounted divisions and Arab irregulars captured Damascus on 1 October. The surviving Ottoman troops were pursued to Aleppo, and the war in the Middle East ended on 31 October.
