The Hejaz war, meanwhile, would be one of dervishes against regular troops. It was the fight of a rocky, mountainous, barren country (reinforced by a wild horde of mountaineers) against an enemy so enriched in equipment by the Germans as almost to have lost virtue for rough-and-tumble war. The hill-belt was a paradise for snipers; and Arabs were artists in sniping. Two or three hundred determined men knowing the ranges should hold any section of them; because the slopes were too steep for escalade. The valleys, which were the only practicable roads, for miles and miles were not so much valleys as chasms or gorges, sometimes two hundred yards across, but sometimes only twenty, full of twists and turns, one thousand or four thousand feet deep, barren of cover, and flanked each side by pitiless granite, basalt and porphyry, not in polished slopes, but serrated and split and piled up in thousands of jagged heaps of fragments as hard as metal and nearly as sharp.
