In the spring of 1916 the Turkish High Command despatched a picked force of brigade strength with German staff-officers attached to reinforce their troops in the Yemen, which had driven back the small British garrison in the Aden Protectorate almost to the narrow confines of Aden Colony itself. This Turkish force travelling south by the Hijaz Railway arrived at Madina in May 1916. Its arrival greatly alarmed the Sharif, who feared that his correspondence with the British might have become known to the Turks, and that the force had been sent to deal with him. In addition, the recent news from Syria of the last and largest crop of political executions had finally convinced the sceptical Faisal that nothing was to be gained by further procrastination and haggling with both sides. The Arab Revolt was accordingly begun on 5 June 1916. Lord Wavell has commented, 'Its value to the British commander was great, since it diverted considerable Turkish reinforcements and supplies to the Hijaz, and protected the right flank of the British armies in their aclvance through Palestine, Further, it put an end to German pro- paganda iiiToSfE-western 'Arabia and removed any danger of the establishment of a German submarine base on the Red Sea. These were important services, and worth the subsidies in gold and munitions expended on the Arab forces/1 That the Revolt did not succeed in raising the civil populations of the Arab provinces is partly due in Syria to the effectiveness of the Turkish repression, and in Iraq to the unsympathetic attitude of the Indian Army authorities, who withheld or minimized the news of the progress of the Revolt in order not to encourage ideas of independence in the local Arab population. The Government of India, aiming at an outright British annexation of Lower Iraq, regarded the Cairo Arab Bureau policy of encouraging Arab independence as vision- ary, and its support of an Arab rising against the Ottoman Sultan- Caliph2 as liable to cause unrest among the ninety million Muslims of India, whose sentimental attachment to the Caliphate was mag- nified by their immunity from the realities of Ottoman rule. The Viceroy of India actually described the Arab Revolt as *a dis- pleasing surprise whose collapse would be far less prejudicial to us 1 The Palestine Campaign, 56. 2 Later Ottoman sultans, and especially Abdul Hamid II with his pan-Is- lamic policy, *had elaborated a fiction that the medieval Caliphate had passed from the last Abbasid to them in 1517. cf.
