The sight which the army witnessed was thrilling. Beyond the flood waters of the river, backed against a sky of staring blue and in the blazing sunlight, the whole of the enemy's position was plainly visible. The long row of shelter trenches was outlined by the white smoke of musketry and dotted with the bright-coloured flags waving defiantly in the wind and with the still brighter flashes of the guns. Behind the entrenchments and among the mud houses and enclosures strong bodies of the jibba-clad Arabs were arrayed. Still further back in the plain a large force of cavalry—conspicuous by the gleams of light reflected from their broad-bladed spears—wheeled and manœuvred. By the Nile all the tops of the palm-trees were crowded with daring riflemen, whose positions were indicated by the smoke-puffs of their rifles, or when some tiny black figure fell, like a shot rook, to the ground. In the foreground the gunboats, panting and puffing up the river, were surrounded on all sides by spouts and spurts of water, thrown up by the shells and bullets. Again the flotilla drew near the narrow channel; again the watching army held their breath; and again they saw the leading boat, the Metemma, turn and run down stream towards safety, pursued by the wild cheers of the Arabs. It was evident that the gunboats were not strong enough to silence the Dervish fire. The want of the terrible Zafir was acutely felt.

The firing had lasted two hours and a half, and the enemy's resistance was no less vigorous than at the beginning of the action. The Sirdar now altered his plans. He saw that his flotilla could not hope to silence the Dervishes. He therefore ordered De Rougemont—who had assumed the command after Colville was wounded—to run past the entrenchments without trying to crush their fire, and steam on to Dongola. To support and cover the movement, the three batteries of artillery under Major Parsons were brought into action from the swampy island of Artagasha, which was connected at this season with the right bank by a shoal. At the same time three battalions of infantry were moved along the river until opposite the Arab position. At 9 A.M. the eighteen guns on the island opened a tremendous bombardment at 1,200 yards range on the entrenchments, and at the same time the infantry and a rocket detachment concentrated their fire on the tops of the palm-trees. The artillery now succeeded in silencing three of the five Dervish guns and in sinking the little Dervish steamer Tahra, while the infantry by a tremendous long-range fire drove the riflemen out of the palms. Profiting by this, the gunboats at ten o'clock moved up the river in line, and, disregarding the fusillade which the Arabs still stubbornly maintained, passed by the entrenchment and steamed on towards Dongola. After this the firing on both sides became intermittent, and the fight may be said to have ended.

Both forces remained during the day facing each other on opposite sides of the river, and the Dervishes, who evidently did not admit a defeat, brandished their rifles and waved their flags, and their shouts of loud defiance floated across the water to the troops. But they had suffered very heavily. Their brave and skilful leader was severely wounded by the splinters of a shell. The wicked Osman Azrak had been struck by a bullet, and more than 200 Ansar had fallen, including several Emirs. Moreover, a long train of wounded was seen to start during the afternoon for the south. It is doubtful, however, whether Bishara would have retreated, if he had not feared being cut off. He seems to have believed that the Sirdar would march along the right bank at once to Dongola, and cross there under cover of his gunboats. Like all Moslem soldiers, he was nervous about his line of retreat. Nor, considering the overwhelming force against him, can we wonder. There was, besides this strategic reason for retiring, a more concrete cause. All his supplies of grain were accumulated in the gyassas which lay moored to the west bank. These vessels were under the close and accurate fire of the artillery and Maxim guns on Artagasha island. Several times during the night the hungry Dervishes attempted to reach their store; but the moon was bright and the gunners watchful. Each time the enemy exposed themselves, a vigorous fire was opened and they were driven back. When morning dawned, it was found that Hafir was evacuated, and that the enemy had retreated on Dongola.

Wad Bishara's anxiety about his line of retreat was unnecessary, for the Sirdar could not advance on Dongola with a strong Dervish force on his line of communications: and it was not desirable to divide the army and mask Hafir with a covering force. But as soon as the Dervishes had left their entrenchments the situation was simplified. At daybreak all the Arab boats were brought over to the right bank by the villagers, who reported that Bishara and his soldiers had abandoned the defence and were retreating to Dongola. Thereupon the Sirdar, relieved of the necessity of forcing the passage, transported his army peacefully to the other bank. The operation afforded scope to his powers of organisation, and the whole force—complete with cavalry, camels, and guns—was moved across the broad, rushing river in less than thirty-six hours and without any apparent difficulty.

The casualties on the 19th were not numerous, and in a force of nearly 15,000 men they appear insignificant. Commander Colville was wounded. One British sergeant and one Egyptian officer were killed. Eleven native soldiers were wounded. The total—fourteen—amounted to less than one per thousand of the troops engaged. Nevertheless this picturesque and bloodless affair has been solemnly called the 'Battle of Hafir.' Special despatches were written for it. It is officially counted in records of service as a 'general action.' Telegrams of congratulation were received from her Majesty and the Khedive. A special clasp was struck. Of all the instances of cheaply bought glory which the military history of recent years affords, Hafir is the most remarkable.

The 20th and part of the 21st were occupied by the passage of the army across the Nile. The troops were still crossing when the gunboats returned from Dongola. The distance of this place by water from Hafir is about thirty-six miles, and the flotilla had arrived opposite the town during the afternoon of the 19th. A few shells expelled the small Dervish garrison, and a large number of sailing vessels were captured. The results of the movement of the gunboats to Dongola must, however, be looked for at Hafir. In consequence of the Sirdar's manœuvre that place was evacuated and the unopposed passage of the river secured.

Bishara continued his retreat during the 20th, and, marching all day, reached Dongola in the evening. Wounded as he was, he re-occupied the town and began forthwith to make preparations for the defence of its considerable fortifications. The knowledge of his employment was not hidden from his enemy, and during the 21st the gunboat Abu Klea, under Lieutenant Beatty, R.N., arrived with the design of keeping him occupied. Throughout the day a desultory duel was maintained between the entrenchments and the steamer. At daylight on the 22nd, Beatty was reinforced by another gunboat, and an unceasing bombardment was made on the town and its defences.

Notwithstanding that the army did not finish crossing the river until the afternoon of the 21st, the Sirdar determined to continue his advance without delay, and the force accordingly marched twelve miles further south and camped opposite the middle of the large island of Argo. At daybreak the troops started again, and before the sun had attained its greatest power reached Zowarat. This place was scarcely six miles from Dongola, and, as it was expected that an action would be fought the next day, the rest of eighteen hours was welcomed by the weary soldiers. All day long the army remained halted by the palms of the Nile bank. Looking through their glasses up the river, the officers might watch the gunboats methodically bombarding Dongola, and the sound of the guns was clearly heard. At intervals during the day odd parties of Dervishes, both horse and foot, approached the outpost line and shots were exchanged.

All these things, together with the consciousness that the culmination of the campaign was now at hand, raised the excitement of the army to a high pitch, and everyone lay down that night warmed by keen anticipations. An atmosphere of unrest hung over the bivouac, and few slept soundly. At three o'clock the troops were aroused, and at half-past four the final advance on Dongola had begun.

It was still night. The full moon, shining with tropical brilliancy in a cloudless sky, vaguely revealed the rolling plains of sand and the huge moving mass of the army. As long as it was dark the battalions were closely formed in quarter columns. But presently the warmer, yellower light of dawn began to grow across the river and through the palms, and gradually, as the sun rose and it became daylight, the dense formation of the army was extended to an array more than two miles long. On the left, nearest the river, marched Lewis's brigade—three battalions in line and the fourth in column as a reserve. Next in order Maxwell's three battalions prolonged the line. The artillery were in the centre, supported by the North Staffordshire Regiment. The gunners of the Maxim battery had donned their tunics, so that the lines and columns of yellow and brown were relieved by a vivid flash of British red. MacDonald's brigade was on the right. David's brigade followed in rear of the centre as a reserve. The cavalry, the Camel Corps, and the Horse Artillery watched the right flank; and on the left the gunboats steamed along the river.
