It was evident now that the Zulu fire was slackening, and three companies of the 13th went out, and, taking posts by the edge of the slope of the cattle-laager, opened fire upon them, as they retired. Every gun was brought to bear upon them, and as, disheartened and beaten, they fell back, Buller and Russell, with every mounted man in camp, sallied out and fell upon them, and, burning with the desire to wipe out their misfortune of the preceding day, chased them for seven miles, like a flock of sheep, cutting down immense numbers. It was ascertained afterwards from prisoners that the Zulu force which attacked was composed of 25,000 men. It was commanded by Tyangwaiyo, with Umbelleni as his second. Many of the leading chiefs of Zululand and 3000 of the king's bravest and best troops fell in the attack on Kambula, and this battle was by far the hottest and best-contested which took place during the war. Upon our side two officers and twenty-one men were killed. The difference between the result of the action at Kambula and that at Isandula was due entirely to the fact that in one case every precaution was taken, every means of defence utilised; while in the other no more attention was paid to any of these points than if the troops had been encamped at Aldershot. Upon the day following the battle Colonel Wood set his men to work to erect further defences at the points which the recent action had shown to be weak, and never ceased work until the place had been made almost impregnable against an assault of savages, however brave. The messenger who carried to Natal the news of the victory of Kambula also took letters from the boys to their parents, acquainting them of their safety; and with the first convoy of wounded on the following day the boys started for home, Colonel Wood having given to each a flattering testimonial as to their gallant conduct in the action, and having presented them with two horses belonging to men of Buller's corps who had fallen in the action, ordering that the horses should be entered as bought for the Queen's service, and the value paid to the relatives of their late owners. Three days' march took the convoy to Utrecht, and the next morning the boys rode home, the distance from there to Newcastle being about forty miles. They were received as if they had risen from the dead, for their letters had not arrived before them, and their parents had of course assumed that they had been killed at Isandula. Both the mothers were in mourning, and their joy at the restoration of their sons was unbounded.
