This is a secret British War Office memorandum, which summarises the Hejaz revolt from its outbreak in June 1916 up to August 1918. More commonly known as the Arab Revolt, it was started by Hussein bin Ali, Sharif of the Hejaz region of Arabia, against the Ottoman Turks, with the co-operation of British and French forces.
At the outbreak of the First World War in 1914, the Hejaz was part of the Ottoman Empire. Many British and French officers were sent to the area to assist the revolt. Among these officers was Captain T E Lawrence, who later became famous as Lawrence of Arabia.
The Arab Revolt played a significant part in the conflict against Turkey. The capture of the Red Sea port of Aqaba in 1917 allowed supplies to reach the Arab forces more easily, while the repeated attacks on the Hejaz Railway disrupted Turkish communications. The revolt in the Hejaz would constitute a steady drain on Turkish military resources during the last two years of the war.
