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 Allenby for its biblical and symbolic resonance.

The battle was the final Allied offensive of the Sinai and Palestine Campaign of the First World War. The contending forces were the Allied Egyptian Expeditionary Force, of three corps including one of mounted troops, and the Ottoman Yildirim Army Group which numbered three armies, each the strength of barely an Allied corps.

These battles resulted in many tens of thousands of prisoners and many miles of territory being captured by the Allies. Following the battles, Daraa was captured on 27 September, Damascus on 1 October and operations at Haritan, north of Aleppo, were still in progress when the Armistice of Mudros was signed ending hostilities between the Allies and Ottomans.

The operations of General Edmund Allenby, the British commander of the Egyptian Expeditionary Force, achieved decisive results at comparatively little cost, in contrast to many offensives during the First World War. Allenby achieved this through the use of creeping barrages to cover set-piece infantry attacks to break a state of trench warfare and then use his mobile forces (cavalry, armoured cars and aircraft) to encircle the Ottoman armies' positions in the Judean Hills, cutting off their lines of retreat.
