World War I: The end of the Battle of Megiddo, the climax of the British Army's Sinai and Palestine campaign under General Edmund Allenby.

The Battle of Megiddo was fought between 19 and 25 September 1918, on the Plain of Sharon, in front of Tulkarm, Tabsor and Arara in the Judean Hills as well as on the Esdralon Plain at Nazareth, Afulah, Beisan, Jenin and Samakh. Its name, which has been described as "perhaps misleading" since very limited fighting took place near Tel Megiddo, was chosen by British commander Edmund Allenby for its biblical and symbolic resonance.

The Sinai and Palestine campaign was part of the Middle Eastern theatre of World War I, taking place between January 1915 and October 1918. The British Empire, the French Third Republic, and the Kingdom of Italy fought alongside the Arab Revolt in opposition to the Ottoman Empire, the German Empire, and the Austro-Hungarian Empire. It started with an Ottoman attempt at raiding the Suez Canal in 1915 and ended with the Armistice of Mudros in 1918, leading to the cession of Ottoman Syria.

Field Marshal Edmund Henry Hynman Allenby, 1st Viscount Allenby, was a senior British Army officer and imperial governor. He fought in the Second Boer War and in the First World War, in which he led the British Empire's Egyptian Expeditionary Force (EEF) during the Sinai and Palestine Campaign against the Ottoman Empire in the conquest of Palestine.
