company of the 1st Battalion, 24th Regiment, was then immediately moved up to a distance of about a mile and a half from the camp, where, at a neck of the Isandhlwana hill, an attempt was made to check the advance of the Zulu army. For a very short time only this manœuvre was successful. [Sidenote: _The Zulu attack._] The Zulu army now advanced in a steady, quiet, and determined manner. The Umcityu regiment formed the right centre, and was engaged with one company of the 1st Battalion, 24th Regiment, and about 200 of Colonel Durnford's natives; the left centre was composed of the Nokenke regiment, which was shelled by the two guns as it advanced. Next on the left, came the Imbonambi regiment, with the Nkobamakosi regiment outside of it, both making a turning movement and threatening the front of the camp, while driving before them a body of Colonel Durnford's mounted men, supported by a patrol of volunteers.[24] The Undi corps, on seeing that the other four regiments had commenced the attack, concealed themselves on the north side of the Isandhlwana mountain, and so turned as to arrive at the western front where the waggon road crosses the neck. On the left front of the camp our infantry behaved with extreme gallantry, and succeeded in thrice repulsing the Nkobamakosi regiment; but the Inbonambi regiment coming up as a reinforcement, enabled the Zulus to push forward along the south front of the camp and accomplish their turning movement. The guns were moved to the right of the Native Contingent, and troops lined the nullah below; three companies of the 1-24th remained on the left of the camp, supported by Durnford's mounted Basutos, who had been driven back. The single company of the 1-24th, which had been thrown out a mile and a half from the camp, was retiring, fighting to the best of their ability, and, of course, was cut off to a man.
