It may have been chance, or it may have been skill, but the third and fourth shells burst over the square. Sheik Kadra smiled grimly and galloped back to the left, where his spearmen were streaming down into the gully. As he joined them a deep growling rose from the plain beneath, like the snarling of a sullen wild beast, and a little knot of tribesmen fell into a struggling heap, caught in the blast of lead from a Gardner. Their comrades pressed on over them, and sprang down into the ravine. From all along the crest burst the hard, sharp crackle of Remington fire. The square had slowly advanced, rippling over the low sandhills, and halting every few minutes to re-arrange its formation. Now, having made sure that there was no force of the enemy in the scrub, it changed its direction, and began to take a line parallel to the Arab position. It was too steep to assail from the front, and if they moved far enough to the right the general hoped that he might turn it. On the top of those ruddy hills lay a baronetcy for him, and a few extra hundreds in his pension, and he meant having them both that day. The Remington fire was annoying, and so were those two Krupp guns; already there were more cacolets full than he cared to see. But on the whole he thought it better to hold his fire until he had more to aim at than a few hundred of fuzzy heads peeping over a razor-back ridge. He was a bulky, red-faced man, a fine whist-player, and a soldier who knew his work. His men believed in him, and he had good reason to believe in them, for he had excellent stuff under him that day. Being an ardent champion of the short-service system, he took particular care to work with veteran first battalions, and his little force was the compressed essence of an army corps. The left front of the square was formed by four companies of the Royal Wessex, and the right by four of the Royal Mallows. On either side the other halves of the same regiments marched in quarter column of companies. Behind them, on the right was a battalion of Guards, and on the left one of Marines, while the rear was closed in by a Rifle battalion. Two Royal Artillery 7 lb. screw-guns kept pace with the square, and a dozen white-bloused sailors, under their blue-coated, tight-waisted officers, trailed their Gardner in front, turning every now and then to spit up at the draggled banners which waved over the cragged ridge. Hussars and Lancers scouted in the scrub at each side, and within moved the clump of camels, with humorous eyes and supercilious lips, their comic faces a contrast to the blood-stained men who already lay huddled in the cacolets on either side.
