To the right understanding of what follows it is necessary to give a somewhat detailed account of the situation. The leading feature of the plain on the southern slopes of which the English camp was placed is the Isandhlwana, or Lion Hill. To the west it rises abruptly, forming the head of the crouching animal it resembles in shape; after forming the back it descends sharply to the east. At both ends are necks or ridges connecting the hill with the smaller undulations of which the more level part of the country consists. The road from Rorke's Drift passes over the western ridge, while on the north facing the camp was a deep ravine and watercourse. To the immediate right was a small copse; beyond this the ground was much broken, irregular krantzes and hills all covered with huge boulders continuing as far as the Buffalo river. To the left of the camp, at the distance of rather more than a mile, ran a long ridge towards the south, connecting it with the great Isandhlwana hill, having on its summit a plateau which, towards the east, opened on to an open and extensive valley. On the extreme left of the camp, looking towards the ridge, were pitched the tents of the Natal Native Contingent; between these and the next two battalions intervened a space of rather less than 300 yards; occupying the centre were the British regular Infantry, just above whom came the headquarters camp of Lord Chelmsford, and in close proximity the headquarters of the column. On the right were the guns and mounted corps lining the edge of the road. Soon after it came over the neck at the back of the camp the ground rose considerably, until the bottom of the precipitous Isandhlwana was reached: the camp therefore literally had its back to a wall.
At six a.m. on the 22nd, a company of the Natal Natives was ordered to scout towards the left, the enemy having appeared in that direction. Whilst these were away Durnford arrived, about nine o'clock, with a rocket battery under Colonel Russell, R.A., 250 mounted natives, and 250 native foot. News was now brought in that the Zulus in very large numbers were driving the pickets before them. A later messenger—a native without uniform, supposed by some to be a Zulu purposely sent with false intelligence—brought the news that the Zulus had divided into three columns, one of which it was supposed was about to attack Colonel Durnford's baggage, still on the road from Rorke's Drift, the other to harass Lord Chelmsford and Colonel Glyn's party in their rear, whilst the third was to hover round and watch the camp. Finally came the news "Zulus retiring in all directions." Colonel Durnford thereupon asked Colonel Pulleine to lend him a couple of the 24th companies, but he declined, saying his orders were to guard the camp, and he could not, under the circumstances, let them go without a positive command. Durnford then determined to go on with his own force, which he divided into three, one part being sent up the hill to the left (east), one to the left front, and the third to the rear, in the direction of Rorke's Drift, to act as an escort for the baggage not yet arrived. The rocket battery was of the party that proceeded to the front under Colonel Durnford in person, to a distance of four or five miles from the camp, but being unable to keep pace with the mounted force was soon left behind.
The body of troops despatched to the left became engaged with the enemy almost immediately, and firing was soon heard all along the crest of the hill. In about an hour Durnford's mounted men re-appeared over the hills, hotly pursued by swarms of Zulus; at the same time the horsemen to the front were also driven back. These, after retiring steadily in skirmishing order for about two miles, came upon the remains of the rocket battery, which had been cut off and broken up, whilst a hand to hand engagement was going on with those who remained. It appears that Russell, whilst advancing with his battery, perceived a body of the enemy on his left, he fired three rockets with some effect; then the Zulus fired a volley, upon which the Native Contingent of infantry retreated, the mules were frightened, and disorder ensued. Taking advantage of this, the enemy charged down the hill, a mêlée ensued, and Russell was killed. As the mounted men retired towards them, the Zulus retreated to their cover, and they, after making a final stand in a spruit about a mile and a half in front of the camp, were eventually driven in.
As the cavalry on the left was being pushed rapidly back, Captain Mostyn was ordered to advance with two companies of 1-24th on the eastern neck of the Isandhlwana, where at a distance of about a mile and a half the Zulus were advancing in large numbers along the north of the Isandhlwana, to outflank the camp on the right, and with this wing of the foe they at once became engaged.
Meanwhile the Zulu left rapidly, and the centre steadily, though more slowly, pushed forward, despite the artillery fire poured into them. Orders were now given for three companies of the 1-24th to occupy ground near the Native Contingent camp, facing the hill over which the Zulu force was streaming. These three companies were supported to their right front by the Natal Native Contingent.
Immediately to the right of the Native Contingent tents came the guns, at a distance of about four hundred yards from the left, and rather more from the right, which was composed of two companies, 24th Regiment and the Mounted Corps, and which occupied the extreme right of the camp and rested on the road. The infantry, in extended order, were by this time engaged along the whole line, and were firing rapidly and steadily. Though the enemy fell in hundreds they kept advancing in apparently undiminished numbers. As rank after rank of the foremost were swept down others pressed on, till at length the companies of the 1-24th above mentioned had been driven back to within 300 yards of that portion of the camp occupied by the Native Contingent. A number of the native infantry now began a hasty retreat to the camp; their officers endeavoured to restrain them, but without effect. Captain Essex pointed this out to Colonel Durnford, who ordered him to take men to that portion of the field, and endeavour to hold the enemy in check. But before this could be executed the natives rushed back in the utmost disorder, thus laying open the right and rear of the companies of the first battalion of the 24th on the left and rear, and the enemy dashing forward at once poured in through this part of the line. In a moment all was disorder, and but few had time to fix bayonets before the Zulus were amongst them, using their assegais with terrible effect. Then followed a scene of utter confusion; horse and foot, black and white, English and Zulu, friend and foe, in a struggling, fighting crowd, pushed gradually through the camp towards the road, where the Zulu right already barred the way. Every man endeavoured to escape towards the Buffalo river, but this was almost an impossibility even for mounted men. The ground was rugged, broken with water-washes, boulder-strewn: ground over which an active native Zulu could progress even faster than a horse. In front ran the river, swift, deep, and fordless, sharp rocks, and deep water alternating. Not half of those who escaped from the camp succeeded in crossing this obstacle: many were drowned, many assegaied, some few shot, and so the pursuit continued right into Natal. The guns moved from right to left across the camp, and endeavoured to get on the Rorke's Drift road. This being occupied by the enemy, they turned off to the left, and coming to grief in a donga had to be abandoned. Major Smith, though wounded, managed to reach the Buffalo, but was there shot.
Lieuts. Melvill and Coghill, seeing all was lost, made an attempt to escape on horseback with the colours of the 24th. Coghill succeeded in getting safely across the Buffalo, but Melvill was struck by a shot just as he was reaching the far bank of the river. Coghill, with heroic devotion, turned back to assist his less fortunate comrade—alas! only to share his fate. Their bodies were subsequently discovered in close proximity, and around them a group of dead Zulus. The colours which they had so desperately defended were also found in the bed of the river, saved from the degradation of capture and contamination by the hands of savages.
In this sad affair there perished twenty-six Imperial officers and 600 non-commissioned officers and men. The loss of the Colonial forces was not less terrible, twenty-four officers being included in the list.
