When I told them of the landing of the five-inch howitzers at Rabegh they rejoiced. Such news nearly balanced in their minds the check of their last retreat down Wadi Safra. The guns would be of no real use to them: indeed, it seemed to me that they would do the Arabs positive harm; for their virtues lay in mobility and intelligence, and by giving them guns we hampered their movements and efficiency. Only if we did not give them guns they would quit.

At these close quarters the bigness of the revolt impressed me. This well-peopled province, from Una Lejj to Kunfida, more than a fortnight's camel march, had suddenly changed its character from a rout of casual nomad pilferers to an eruption against Turkey, fighting her, not certainly in our manner, but fiercely enough, in spite of the religion which was to raise the East against us in a holy war. Beyond anything calculable in figures, we had let loose a passion of anti-Turkish feeling which, embittered as it had been by generations of subjection, might die very hard. There was among the tribes in the fighting zone a nervous enthusiasm common, I suppose, to all national risings, but strangely disquieting to one from a land so long delivered that national freedom had become like the water in our mouths, tasteless.

Later I saw Feisal again, and promised to do my best for him. My chiefs would arrange a base at Yenbo, where the stores and supplies he needed would be put ashore for his exclusive use. We would try to get him officer-volunteers from among the prisoners of war captured in Mesopotamia or on the Canal. We would form gun crews and machine-gun crews from the rank and file in the internment camps, and provide them with such mountain guns and light machine-guns as were obtainable in Egypt. Lastly, I would advise that British Army officers, professionals, be sent down to act as advisers and liaison officers with him in the field.

This time our talk was of the pleasantest, and ended in warm thanks from him, and an invitation to return as soon as might be. I explained that my duties in Cairo excluded field work, but perhaps my chiefs would let me pay a second visit later on, when his present wants were filled and his movement was going forward prosperously. Meanwhile I would ask for facilities to go down to Yenbo, for Egypt, that I might get things on foot promptly. He at once appointed me an escort of fourteen Juheina Sherifs, all kinsmen of Mohamed Ali ibn Beidawi, the Emir of the Juheina. They were to deliver me intact in Yenbo to Sheikh Abd el Kadir el Abdo, its Governor.

CHAPTER XVI

Leaving Hamra as dusk fell, we marched back down Wadi Safra until opposite Kharma, where we turned to the right up the side valley. It was closely grown with stiff brushwood, through which we drove our camels strenuously, having tucked up the streamers of our saddle-bags to save them from being shredded by the thorns. Two miles later we began to climb the narrow pass of Dhifran, which gave evidence even by night of labour expended on the road. It had been artificially smoothed, and the stones piled at each side into a heavy wall of protection against the rush of water in the rains. Parts had been graded, and were at times carried on a causeway built seemingly six or eight feet high, of great blocks of uncut stone: but it had been breached at every turn by torrents, and was in terrible ruin.

The ascent lasted perhaps for a mile; and the steep descent on the other side was about the same. Then we got to the level and found ourselves in a much broken country of ridges, with an intricate net of wadies whose main flow was apparently towards the south-west. The going was good for our camels. We rode for about seven miles in the dark, and came to a well, Bir el Murra, in a valley bed under a very low bluff, on whose head the square courses of a small fort of ashlar stood out against the starry sky. Conceivably both fort and causeway had been built by an Egyptian Mameluke for the passage of his pilgrim-caravan from Yenbo.

We halted there for the night, sleeping for six hours, a long luxury upon the road, though this rest was broken twice by challenges from half-seen mounted parties who had found our bivouac. Afterwards we wandered among more small ridges until the dawn showed gentle valleys of sand with strange hills of lava hemming us about. The lava here was not the blue-black cinder-stone of the fields about Rabegh: it was rust-coloured, and piled in huge crags of flowing surface and bent and twisted texture, as though played with oddly while yet soft. The sand, at first a carpet about the foot of the dolerite, gradually gained on it. The hills got lower, with the sand banked up against them in greater drifts, till even the crests were sand-spattered, and at last drowned beyond sight. So, as the sun became high and painfully fierce, we led out upon a waste of dunes, rolling southward for miles down hill to the misty sea, where it lay grey-blue in the false distance of the heat.

The dunes were narrow. By half-past seven we were on a staring plain of glassy sand mixed with shingle, overspread by tall scrub and thorn bushes, with some good acacia trees. We rode very fast across this, myself in some discomfort; for I was not a skilled rider: the movement exhausted me, while sweat ran down my forehead and dripped smartingly into my gritty, sun-cracked eyelids. Sweat was actually welcome when a drop fell from the end of a tuft of hair, to strike on the cheek cold and sudden and unexpected like a splash, but these refreshments were too few to pay for the pain of heat. We pressed on, while the sand yielded to pure shingle, and that again hardened into the bed of a great valley, running down by shallow, interwoven mouths towards the sea.

We crossed over a rise, and from the far side opened a wide view, which was the delta of Wadi Yenbo, the largest valley of Northern Hejaz. It seemed a vivid copse of tamarisk and thorn. To the right, some miles up the valley, showed darkly the palm-groves of Nakhi Mubarak, a village and gardens of the Beni Ibrahim Juheina. In the distance, ahead of us, lay the massive Jebel Rudhwa, brooding always so instantly over Yenbo, though more than twenty miles away. We had seen it from Masturah, for it was one of the great hills of Hejaz, the more wonderful because it lifted itself in one clear edge from flat Tehama to crest. My companions felt at home in its protection; so, as the plain was now dancing with unbearable heat, we took shade under the branches of a leafy acacia beside the path, and slumbered through the middle day.

In the afternoon we watered our camels at a brackish little water hole in the sand bed of a branch watercourse, before a trim hedge of the feathery tamarisk, and then pushed on for two more happy hours. At last we halted for the night in typical Tehama country of bare slowly-swelling sand and shingle ridges, with shallow valleys.

The Sherifs lit a fire of aromatic wood to bake bread and boil coffee; and we slept sweetly with the salt sea air cool on our chafed faces. We rose at two in the morning, and raced our camels over a featureless plain of hard shingle and wet sand to Yenbo, which stood up with walls and towers on a reef of coral rag twenty feet above our level. They took me straight through the gates by crumbling, empty streets--Yenbo had been half a city of the dead since the Hejaz Railway opened--to the house of Abd el Kader, Feisal's agent, a well-informed, efficient, quiet and dignified person, with whom we had had correspondence when he was postmaster in Mecca, and the Survey in Egypt had been making stamps for the new State. He had just been transferred here.
