From there they traveled on to Wadi Yenbo, a deep, wide valley, scoured by flash floods, where heat mirages shimmered before their eyes. They rested during the worst heat of the day under the sparse branches ofan acacia tree, then rode on through sand and shingle until they halted for the night, and felt at last like a balm “a salt wind from the sea blowing over our chafed faces.” After baking bread and boiling coffee, they rested until two in the morning, then moved on over rough country—hard, slow going until they arrived at a salt flat, which they raced over, reaching the gates of Yenbo, perched high above the salt flat on a coral cliff, at six in the morning.

Here Lawrence spent four days in the “picturesque, rambling house” of Sheikh Abd el Kader el Abdo, Feisal’s “agent” here—at this point Yenbo was by no means safe, since the local sharif and emir was known to be pro-Turk. While waiting for the Royal Navy to appear, Lawrence wrote down everything he had seen. His reports were remarkable documents, long (in this case 17,000 words), detailed, full of trenchant and well-expressed military and political opinions, and containing a wealth of invaluable information and observations on everything from the position of wells to the most minute topographical observations. This was to be an important factor in Lawrence’s swift rise—even those who did not much like him, or agree with him about the importance and the direction of the Arab Revolt, were often persuaded by his written reports, which reached the very highest levels of the War Office and even the war cabinet, and confirmed that here, at any rate, was a uniquely well informed and self-confident young officer, with strong opinions formed on the spot, rather than in an office in Cairo 800 miles from the fighting.

However, when Captain William (“Ginger”) Boyle, RN, appeared at last with HMS Suva, a former Australian freighter, on November 1, Lawrence failed to make a good initial impression; he was “travel-stained,” he had abandoned his luggage, and he wore a native head cloth instead of his uniform cap, which he had lost during his arduous days of desert travel. Boyle, the senior officer of the Red Sea Naval Patrol, was a large, bluff, hearty, quick-tempered naval type (he would go on to a long career, ending as Admiral of the Fleet the Twelfth Earl of Cork and Orrery, GCB, GCVO). He had been a fervent supporter of the Arab Revolt from its beginning—and generous with supplies, ammunition, and offshorebombardments of Turkish positions—but not to the point of wishing to see a British officer dressed like a native, or sauntering casually onto the bridge of HMS Suva with his hands in his pockets, as if the vessel were a cab he had just hailed on the Strand. Lawrence’s unmilitary appearance, his failure to salute, and his strongly expressed opinions on every subject under the sun, including the Royal Navy, sent Boyle’s temper soaring; but despite Lawrence’s diminutive height, improper attire, and irritating habit of omniscience, his combination of enthusiasm, sincerity, and practical common sense eventually put Boyle at ease, and by the time they reached Jidda they were friends, and would remain so for life. Boyle had discovered the most striking thing about Lawrence: however far-fetched his ideas might seem at first, he usually knew what he was talking about.

In Jidda they found HMS Euryalus, the flagship, with the commander in chief of the Egyptian Squadron, Vice-Admiral Sir Rosslyn Wemyss, GCB, CMG, MVO, on board, on his way to Port Sudan to meet with General Sir Reginald Wingate, governor-general of the Sudan and sirdar of the Egyptian army, at Khartoum. This was fortunate for Lawrence: Wemyss—a widely respected naval figure and a friend of King George V—combined impeccable connections with a fervent belief in the possibilities of the Arab Revolt. Indeed, a visit on board Wemyss’s flagship had been one factor clinching the Arabs’ decision to revolt: they were awed by the size of its guns, and indeed astonished that a vessel so big and heavy could float at all.

Wemyss was no stranger to odd behavior—he kept in his day cabin on board Euryalus a gray parrot trained to cry out, in a pronounced Oxford accent, “Damn the kaiser!"—and he liked Lawrence, whatever headgear Lawrence wore. Wemyss, who would come to Lawrence’s help again, always appearing at the right moment unexpectedly like a wizard in a pantomime, took him across the Red Sea to Port Sudan, and from there to Wingate’s headquarters in Khartoum, where Wingate—the original and firmest supporter of the Arab Revolt—read his reports and listened to his opinion that the situation in the Hejaz was not dire, as many peoplein Cairo supposed, but “full of promise.” What the Arabs needed, Lawrence said, was not British troops, whose appearance at Rabegh would cause the tribesmen to give up the fight and return to their herds, but merely a few Arabic-speaking British technical advisers, explosives, and a modest number of modern weapons.

As it happened, this was exactly the message that the chief of the imperial general staff (CIGS) in London most wanted to receive, for the terrible battles on the western front in 1916 made manpower a crucial question. Verdun had cost the French nearly 500,000 casualties, and the first Battle of the Somme, launched by the British to support the French at Verdun, would cost them more than 600,000 casualties, 60,000 on the first day alone; and General Murray, the commander in chief of the Egyptian Expeditionary Force in Cairo, was under constant pressure from the CIGS in London to squeeze every possible division, brigade, and person out of his army for immediate dispatch to France.

Lawrence was perhaps the only person in the world who would have described his three or four days at Wingate’s palace in Khartoum—on the steps of which Lawrence’s predecessor in the imagination of the British public as a desert adventurer, General Gordon, had been murdered—as “cool and comfortable.” Everybody else who had visited Khartoum at any time of year described it as hellishly hot, though certainly Wingate’s palace was plush and lavish after the desert, and surrounded by beautiful gardens. When Lawrence was not conferring with Wingate and Wemyss, he spent his time reading Malory’s Morte d’Arthur, a pleasure interrupted by the kind of event that seldom failed to occur at the right moment in Lawrence’s career. His host, Sir Reginald Wingate, was abruptly informed that Sir Henry McMahon had been recalled from Cairo to Britain, and Wingate was to take McMahon’s place as British high commissioner in Egypt. Thus supreme control of Egypt would pass from the hands of a civilian into the firmer hands of a soldier who supported the revolt passionately, who would be in direct command of the British end of it, and who knew Lawrence well. At the same time the change would bring to an end a curious division: political responsibility for the Arab Revolt hadbeen in Cairo and military responsibility in Khartoum, and this had been a source of delay and confusion to all concerned.

Both senior officers read and were impressed by Lawrence’s reports from the Hejaz. They were still more impressed by Lawrence himself; and it must be noted that, as was so often the case with Lawrence, though still a temporary second-lieutenant he was conferring as an equal with an admiral and with his excellency the governor-general of the Sudan and sirdar of the Egyptian army. This easy access to the most senior officers and officials was due not to Lawrence’s social position, which was less than negligible, but to his acute mind; to his strong opinions, which were based on facts he had personally observed; and to his view of policy and strategy, which was far broader and more imaginative than that of most junior officers—or, indeed, most senior ones.

In short, part of the reason for Lawrence’s success was that he knew what he was talking about, and could make his points succinctly even among men far senior to him in age, experience, and rank. Even the busiest of officials made time to listen to what Lawrence had to say: generals, admirals, high commissioners, and princes now, and in the not very distant future, also artists, scholars, prime ministers, presidents, kings, and giants of literature. Lawrence himself, though reasonably respectful of rank unless provoked, seemed almost unconscious of it, treated others as if they were all equals and was himself treated as an equal by many of the highest figures in the world. He may have been the only person in twentieth-century Britain who was just as much at ease with King George V as with a hut full of RAF recruits. Certainly, he eventually won Wingate over completely, and Wingate was not an easy man for a temporary second-lieutenant without a proper cap or uniform to win over.
