Clayton a few days later told me to return to Arabia and Feisal. This being much against my grain I urged my complete unfitness for the job: said I hated responsibility — obviously the position of a conscientious adviser would be responsible — and that in all my We objects had been gladder to me than persons, and ideas than objects. So the duty of succeeding with men, of disposing them to any purpose, would be doubly hard to me. They were not my medium: I was not practised in that technique. I was unlike a soldier: hated soldiering. Of course, I had read the usual books (too many books), Clausewitz and Jomini, Mahan and Foch, had played at Napoleon’s campaigns, worked at Hannibal’s tactics, and the wars of Belisarius, like any other man at Oxford; but I had never thought myself into the mind of a real commander compelled to fight a campaign of his own.

Last of all I reminded Clayton, relevantly, that the Sirdar had telegraphed to London for certain regular officers competent to direct the Arab war. The reply was that they might be months arriving, and meanwhile Feisal must be linked to us, and his needs promptly notified to Egypt. So I had to go; leaving to others the Arab Bulletin I had founded, the maps I wished to draw, and the file of the war-changes of the Turkish Army, all fascinating activities in which my training helped me; to take up a role for which I felt no inclination. As our revolt succeeded, onlookers have praised its leadership: but behind the scenes lay all the vices of amateur control, experimental councils, divisions, whimsicality.

My journey was to Yenbo, now the special base of Feisal’s army, where Garland single-handed was teaching the Sherifians how to blow up railways with dynamite, and how to keep army stores in systematic order. The first activity was the better. Garland was an enquirer in physics, and had years of practical knowledge of explosives. He had his own devices for mining trains and felling telegraphs and cutting metals; and his knowledge of Arabic and freedom from the theories of the ordinary sapper-school enabled him to teach the art of demolition to unlettered Beduin in a quick and ready way. His pupils admired a man who was never at a loss.

Incidentally he taught me to be familiar with high explosive. Sappers handled it like a sacrament, but Garland would shovel a handful of detonators into his pocket, with a string of primers, fuse, and fusees, and jump gaily on his camel for a week’s ride to the Hejaz Railway. His health was poor and the climate made him regularly ill. A weak heart troubled him after any strenuous effort or crisis; but he treated these troubles as freely as he did detonators, and persisted till he had derailed the first train and broken the first culvert in Arabia. Shortly afterwards he died.

Things in Hejaz had changed a good deal in the elapsed month. Pursuing his former plan, Feisal had moved to Wadi Yenbo, and was trying to make safe his rear before going up to attack the railway in the grand manner. To relieve him of the burdensome Harb tribes, his young half-............
