After its arrival in Egypt the 2nd Battalion saw active service against the Ottoman Empire and later took part in the Palestine campaign, the second largest campaign by force totals during the First World War. It fought in the Autumn Offensive, seeing their first action during the Battles of Gaza. It was involved in many other actions during the campaign, including the Battle of Mughar Ridge in November 1917 and the capture of Jerusalem in December. On 19 September 1918, just a few months before the conclusion of the war, the Megiddo Offensive, began and the battalion was involved in the capture of Sharon. For its part in the campaign the 3rd Gurkhas gained seven Battle Honours and the Theatre Honour "Palestine 1917–18" after such honours were granted to units in the 1920s.
