From Army of Empire: The Untold Story of the Indian Army in World War I, by George Morton-Jack (Basic Books, 2018), Kindle pp. 479-482:
On 28 September 1918, Lawrence, the Arab forces and their Pukhtun and Gurkha attachments joined up with the main body of Allenby’s Indian cavalry at the southern Syrian town of Dera, a Turkish railway junction between Amman and Damascus. Over the following four days, Lawrence had a series of personal run-ins with the Indian cavalry at Dera that were to leave him with a lifelong contempt for the Indian Army. Indeed, in his autobiographical masterpiece Seven Pillars of Wisdom (1926) he would belittle the Indian troops in Palestine as ‘not worthy of the privilege of space’ in the desert, being ‘something puny’ with minds ‘like slow sheep’.
The sourness started outside Dera when Lawrence, on horseback, trotted up to the advance guard of the 2nd Gardner’s Horse. Freshly shaved and in clean Arab robes with a white headdress, intending to impress as an authoritative Arab military leader, he called out, ‘I am Colonel Lawrence. Where is your General? Take me to him at once.’ The young British officer of the guard, Dysart Whitworth, had not slept for fifty hours on the march, and did not like Lawrence’s tone; he snapped back that he was commanding in action, was not a guide, and Lawrence was ‘a bloody fool’. A yelling impasse ensued which Lawrence backed down from, riding off in fury shouting, ‘I’ll have you court martialled!’ Shortly afterwards, while the robed Lawrence was driving in his Rolls-Royce with a Bedu escort, he came upon another Indian advance guard–this time of the 34th Poona Horse under their senior Indian officer Hamir Singh, a veteran of First Ypres. Mistaking Lawrence and his Bedu for Turkish irregulars, Hamir Singh’s guard charged mounted at them, driving off the Bedu and taking Lawrence prisoner as a suspected spy. Another heated argument broke out, with Hamir Singh refusing to let an apoplectic Lawrence go for some time.
On 1 October Lawrence drove into Damascus triumphantly in his Rolls-Royce with his Arab irregulars as liberators, just ahead of the Egyptian Expeditionary Force’s Indian and other Allied troops. The capture of the city, 120 miles north of Allenby’s Megiddo start line on 19 September, confirmed the crushing success of the offensive. In weighing up the contribution of Lawrence’s Arabs, George Barrow would always repeat what a captured Turkish divisional commander told him: ‘The Arabs gave us pin pricks; the British–blows with a sledge hammer.’ The Arabs had indeed been marginal, and the hammer blows had been struck most frequently by the Indian infantry and cavalry.
In the week leading up to Lawrence’s entry into Damascus, Indian cavalry regiments had been decisive in the pursuit of the retreating Turkish divisions and German Asia Corps all the way up from Megiddo. They had taken the majority of the Allies’ 75,000 predominantly Turkish prisoners, along with several towns–for instance, the Jodhpur Lancers had seized Haifa on 23 September with a mounted charge through the streets. The Indian cavalry’s feat of arms at Megiddo was in fact the last time in western military history mounted troops played a leading role.
The Turks’ own part in their downfall in Palestine was rooted not so much in their inferiority in numbers, guns or aircraft, all of which they had in good quantities for defence, as in their sapped spirit. This accounted for the large numbers of prisoners who surrendered easily. By mid-1918 the resolve of the Turkish Army was not what the Indians had seen at Gallipoli in 1915, on the Tigris in 1916 or at Gaza in 1917. The long war had gradually worn down them and their supply system, and by Megiddo they had little energy to carry on. Some of the Turkish troops there had fought hard, but many had lost heart, with no boots on their feet and almost no food to eat, at one with their artillery horses who were too under-nourished to pull back half their guns on the retreat. On account of the Turkish Army’s scrawny appearance and reduced fighting capacity at Megiddo compared to the well fed, trained and equipped Egyptian Expeditionary Force, one British staff officer remarked that Allenby’s offensive had ultimately been that of an Indian tiger against a Turkish tomcat.
