For more than two hours the force advanced, moving across smooth swells of sand broken by rocks and with occasional small bushes. Several shallow khors traversed the road, and these rocky ditches, filled with a strange, sweet-scented grass, delayed the brigades until the pace was hardly two miles an hour. The smell of the grass was noticed by the alert senses of many, and will for ever refresh in their minds the strong impression of the night. The breeze which had sprung up at sundown gradually freshened and raised clouds of fine sand, which deepened the darkness with a whiter mist.
At nine o'clock the army halted in a previously selected space, near the deserted village of Mutrus and about two miles from the river. Nearly half the distance to Mahmud's zeriba was accomplished, and barely four miles in the direct line divided the combatants; but since it was not desirable to arrive before the dawn, the soldiers, still formed in their squares, lay down upon the ground. Meat and biscuits were served out to the men. The transport animals went by relays to the pools of the Atbara bed to drink and to replenish the tanks. All water-bottles were refilled, pickets being thrown out to cover the business. Then, after sufficient sentries had been posted, the army slept, still in array.
During the halt the moon had risen, and when at one o'clock the advance was resumed, the white beams revealed a wider prospect and, glinting on the fixed bayonets, crowned the squares with a sinister glitter. For three hours the army toiled onwards at the same slow and interrupted crawl. Strict silence was now enforced, and all smoking was forbidden. The cavalry, the Camel Corps, and the five batteries had overtaken the infantry, so that the whole attacking force was concentrated. Meanwhile the Dervishes slept.
At three o'clock the glare of fires became visible to the south, and, thus arrived before the Dervish position, the squares, with the exception of the reserve brigade, were unlocked, and the whole force, assuming formation of attack, now advanced in one long line through the scattered bush and scrub, presently to emerge upon a large plateau which overlooked Mahmud's zeriba from a distance of about 900 yards.
It was still dark, and the haze that shrouded the Dervish camp was broken only by the glare of the watch-fires. The silence was profound. It seemed impossible to believe that more than 25,000 men were ready to join battle at scarcely the distance of half a mile. Yet the advance had not been unperceived, and the Arabs knew that their terrible antagonists crouched on the ridge waiting for the morning; For a while the suspense was prolonged. At last, after what seemed to many an interminable period, the uniform blackness of the horizon was broken by the first glimmer of the dawn. Gradually the light grew stronger until, as a theatre curtain is pulled up, the darkness rolled away, the vague outlines in the haze became definite, and the whole scene was revealed.
The British and Egyptian army lay along the low ridge in the form of a great bow—the British brigade on the left, MacDonald in the centre, Maxwell curving forward on the right. The whole crest of the swell of ground was crowned with a bristle of bayonets and the tiny figures of thousands of men sitting or lying down and gazing curiously before them. Behind them, in a solid square, was the transport, guarded by Lewis's brigade. The leading squadrons of the cavalry were forming leisurely towards the left flank. The four batteries and a rocket detachment, moving between the infantry, ranged themselves on two convenient positions about a hundred yards in front of the line of battalions. All was ready. Yet everything was very quiet, and in the stillness of the dawn it almost seemed that Nature held her breath.
Half a mile away, at the foot of the ridge, a long irregular black line of thorn bushes enclosed the Dervish defences. Behind this zeriba low palisades and entrenchments bent back to the scrub by the river. Odd shapeless mounds indicated the positions of the gun-emplacements, and various casemates could be seen in the middle of the enclosure. Without, the bushes had been cleared away, and the smooth sand stretched in a gentle slope to where the army waited. Within were crowds of little straw huts and scattered bushes, growing thicker to the southward. From among this rose the palm-trees, between whose stems the dry bed of the Atbara was exposed, and a single pool of water gleamed in the early sunlight. Such was Mahmud's famous zeriba, which for more than a month had been the predominant thought in the minds of the troops. It was scarcely imposing, and at first the soldiers thought it deserted. Only a dozen stray horsemen sat silently on their horses outside the entrenchment, watching their enemies, and inside a few dirty-white figures appeared and disappeared behind the parapets. Yet, insignificant as the zeriba looked, the smoke of many fires cooking the morning meal—never to be eaten—showed that it was occupied by men; and gay banners of varied colour and device, flaunting along the entrenchments or within the enclosure, declared that some at least were prepared to die in its defence.
The hush of the hour and the suspense of the army were broken by the bang of a gun. Everyone on the ridge jumped up and looked towards the sound. A battery of Krupps a little to the right of the Cameron Highlanders had opened fire. Another gun further to the right was fired. Another shell burst over the straw huts among the palm-trees. The two Maxim-Nordenfeldt batteries had come into action. The officers looked at their watches. It was a quarter-past six. The bombardment had begun.
Explosion followed explosion in quick succession until all four batteries were busily engaged. The cannonade grew loud and continuous. The rocket detachment began to fire, and the strange projectiles hissed and screamed as they left the troughs and jerked erratically towards the zeriba. In the air above the enclosure shell after shell flashed into existence, smote the ground with its leaden shower, and dispersed—a mere film—into the haze and smoke which still hung over the Dervish encampment. At the very first shot all the dirty-white figures disappeared, bobbing down into their pits and shelters; but a few solitary horsemen remained motionless for a while in the middle of the enclosure, watching the effect of the fire, as if it had no concern with them. The British infantry stood up on tip-toe to look at the wonderful spectacle of actual war, and at first every shell was eagerly scrutinised and its probable effect discussed. But the busy gunners multiplied the projectiles until so many were alive in the air at once that all criticism was prevented. Gradually even the strange sight became monotonous. The officers shut up their glasses. The men began to sit down again. Many of them actually went to sleep. The rest were soon tired of the amazing scene, the like of which they had never looked on before, and awaited impatiently further developments and 'some new thing.'
After the bombardment had lasted about ten minutes a great cloud of dust sprang up in the zeriba, and hundreds of horsemen were seen scrambling into their saddles and galloping through a gap in the rear face out into the open sand to the right. To meet the possibility of an attempt to turn the left flank of the attack, the eight squadrons of cavalry and two Maxim guns jingled and clattered off in the direction of the danger. The dust, which the swift passage of so many horsemen raised, shut the scene from the eyes of the infantry, but continual dust-clouds above the scrub to the left and the noise of the Maxims seemed to indicate a cavalry fight. The Baggara horse, however, declined an unequal combat, and made no serious attempt to interfere with the attack. Twice they showed some sort of front, and the squadrons thought they might find opportunity to charge; but a few rounds from the Maxims effectually checked the enemy, inflicting on each occasion the loss of about twenty killed and wounded. With the exception of one squadron detached on the right, the Egyptian cavalry force, however, remained on the left flank, and shielded the operations of the assaulting infantry.
