What is harder to understand is why Lawrence included the story in his book at all—it feels out of place, squeezed in between a long description of how he selected his bodyguard and the plans for his campaign against Talifeh. It is preceded by a puzzling disquisition on sex in Arabia, in which Lawrence remarks that “the sacredness of women in nomad Arabia forbade prostitution” (yet there were three prostitutes in Aqaba),and argues that “voluntary and affectionate” sexual relationships among Bedouin were better than “the elaborate vices of Oriental cities” or—in an odd aside—"the bestialities of their peasantry with goats and asses.”

Aside from the fact that stories about peasants having sex with their animals are common to every country and culture, it is hard to see how “the elaborate vices” of Oriental cities would be different from or worse than those practiced in the open air at Aqaba. Granted that frankness about acts and words that were still taboo was one of the things Lawrence sought to bring to literature later on, there is still something disturbing about a man who has recently endured a savage whipping himself feeling “rather inclined to laugh” at the spectacle of two young men just having been whipped. There is also an uneasy feeling of sexual ambivalence—or perhaps simply a lack of sympathy with or understanding of the sexual impulse, which seems to affect Lawrence whenever he writes about what was, for him, an uncongenial subject.

By the second week of January, Lawrence was on the move again. He rode out into the desert with his bodyguard to reconnoiter a ridge overlooking the railway station Jurf el Derawish, thirty miles north of Maan. Deciding that the position was a good one, he brought up Nuri as-Said, with 300 Arab regulars and a mountain gun. Under the cover of darkness, he cut the railway line above and below Jurf, and at dawn opened fire on the station with the mountain gun, silencing the Turkish artillery. Then the Beni Sakhr charged on camels from their position behind the ridge, where they had been hidden. The Turkish garrison, surprised and overwhelmed, surrendered when Nuri captured the Turks’ own gun and turned it on the station at point-blank range. Twenty Turks were wounded or killed, and nearly 200 were taken prisoner—but the discovery of two trains in the station loaded with delicacies for the officers in Medina set the Arabs off on a prolonged burst of looting and gorging, and as a result they missed an opportunity to destroy another train as it approached the station.

During two days of extreme cold, heavy snow, and hail, the tribesaround Shobek, near Petra, stormed and took the town. Hearing the news Nuri rode on to Tafileh through the night, and halting at the edge of the cliff above the town at dawn, he demanded that the town surrender or be shelled, even though his gun and his troops were far behind him. The Turks hesitated—they too had heard the news of the capture of Jurf and Shobek, but they were 150 men, and well armed. Then Auda Abu Tayi cantered out in full sight of them, his heavy cloak flowing behind him, and called out: “Dogs! Do you not know Auda?”

In Liddell Hart’s words, “The defences of Tafila* collapsed before his trumpeting voice as those of Jericho had once collapsed before Joshua.” Holding on to the place was harder, however, since the Arabs immediately began quarreling among themselves, and the majority of the townspeople who were Arab were divided in their loyalty to different clans. Lawrence arrived, and began to spread around gold sovereigns to induce peace, but he had hardly even begun to restore order when news reached him that a sizable Turkish force was marching from Amman to retake Tafileh, consisting of “three … battalions of infantry, a hundred cavalry, two mountain howitzers and twenty-seven machineguns … led by Hamid Fakhri Bey, the commander of the 48th Division.” By late afternoon, the Turks had brushed aside the Arab mounted pickets guarding Wadi Hesa, “a gorge of great width and depth and difficulty” ten miles north of Tafileh, which, like almost every place in Palestine and western Syria, was part of biblical geography, cutting off the land of Moab from that of Edom. Lawrence had been elated by the capture of Jurf, Shobek, and Tafileh, but he was dismayed by the swift response of the Turks; he had assumed they would be too busy defending Amman to worry about retaking Tafileh.

In ordinary circumstances, the right thing for the Arabs to do in the face of a powerful Turkish advance would have been to withdraw, first destroying whatever they could in Tafileh, and carrying away as much booty as they could load on their camels. Instead Lawrence decided to fight a conventional battle, marking a new stage in the development of theArab army. He was moved in part by the plight of the residents of Tafileh, whom the Turks would certainly punish severely for surrendering the town, and in part by a desire to prove to Allenby that the Arabs could fight and win a conventional battle.

Until now, Lawrence had been following his own maxim: “To make war upon rebellion is messy and slow, like eating soup with a knife,” and his aim was to keep the Turks trying to eat soup with a knife for as long as possible. His model was Marshal de Saxe, who had written, “I am not in favor of giving battle, especially at the outset of a war—I am even convinced that an able general can wage war his whole life without being compelled to do so.” Now, Lawrence, a convinced admirer of de Saxe, was following instead the formula of Napoleon: “There is nothing I desire so much as a great battle.” He had not changed his opinion about de Saxe, whose maxims would remain the essential basis for all guerrilla wars on into the present, but he recognized the political reality, which was that the British, and especially the French, were unlikely to take the Arabs’ claims to territory seriously until the Arabs had demonstrated an ability to hold their ground and beat the Turks in a conventional battle of positions. It was not that Lawrence’s philosophy of war had changed; it was that politics, and its by-product, public relations—Lawrence had already learned something from Lowell Thomas—required something more than blowing up bridges and looting trains if the Arabs were to get Damascus. Since Lawrence considered it his job to get them Damascus, he made up his mind to fight the Turks at Tafileh.

In desert skirmishes Lawrence’s command was direct and unchallenged; by contrast, the force at Tafileh had, if anything, too many leaders for its size. The overall commander of the march toward the Dead Sea was Feisal’s younger half brother Zeid, “a cool and gallant fighter,” who did not have much experience directing a battle but who, as a son of the sharif of Mecca (now king of the Hejaz), had the respect of all the tribes, and even of Auda. The uniformed regulars were under the command of Major-General Jaafar Pasha, a former officer in the Turkish army and now Feisal’s chief of staff, a competent professional soldier. Lawrence’sbodyguard was led by Abdulla el Nahabi, a fearless adventurer with a series of murders and assaults on his head, as well as a price. As for the Bedouin, the bulk of them were divided into two mutually hostile factions, since Auda’s tribe and the Motalga were traditional blood enemies. By means of a lavish payment in gold, Auda was sent “back to his desert beyond the railway to contain the garrisons of the Turkish stations,” thus removing one source of friction, but clearly the battle could not be won unless Lawrence took command of it, though he passed his orders through the Arabs’ chief.

It is always difficult to compare battles, but to anybody interested in military history, once allowance is made for the difference in climate and scale, the topography of Tafileh bears a startling resemblance to that of Gettysburg. Lawrence, then, was in the position of Lee, and Hamid Fakhri Bey in the position of Meade, when Longstreet launched his attack against Cemetery Ridge on the afternoon of July 3, 1863—with the crucial difference that Lawrence succeeded.
