Early in June some messengers arrived in Lord Chelmsford's camp from Cetewayo. Lord Chelmsford told them that before any negotiations could be entered into, the whole of the spoil taken at Isandula, especially the two captured 7-pounder guns, must be restored. Considerable delays now took place, and for three weeks a force of Englishmen sufficient to march through and through Zululand in every direction was kept doing nothing at a distance of three days' march from the enemy's capital. So extraordinary and unaccountable was the delay that the English government appointed Sir Garnet Wolseley to go out to supersede Lord Chelmsford. Upon the receipt of this news preparations for an advance were at last made. On the 21st General Newdigate's column reached the right bank of the Umlatoosi. General Crealock, who commanded the division which was operating by the sea, also moved forward about this time, but met with such difficulties, owing to the sickness which attacked his transport-train, that he was unable to co-operate with the first division, although his force did service by occupying a large number of the enemy, who would otherwise have been free to act against the main column. Between the 24th and 26th General Newdigate's and Wood's columns advanced but six miles. But Buller with his horse scouted ahead, and cut up a number of Zulus who were engaged in burning the grass, to hinder the advance of the horses and cattle. On the 26th Colonel Drury-Lowe, with the light cavalry, 450 of Buller's men and two guns, went out and attacked and burnt five large military kraals. On the 27th the column advanced five miles towards Ulundi, leaving their tents behind them, and taking only 200 ammunition-waggons and ten days' rations; 500 infantry were left to guard the stores. On the afternoon of that day some messengers came in from Cetewayo, bringing 150 of the cattle captured at Isandula, together with a pair of elephant's tusks, and a letter written in English by a trader captured at Isandula. The letter said that the king could not comply with all Lord Chelmsford's commands, as the arms taken from us at Isandula were not brought to him, and that it was beyond his power as a king to order or compel any of his regiments to lay down their arms. He said the cannons should be sent in, and on the receipt of the cattle and these weapons the English must retire from Zululand. The trader had written in a corner of the letter, in pencil, a few words of warning, and an intimation that Cetewayo had with him at Ulundi a picked force of 20,000 men. Lord Chelmsford refused to receive the tusks, and told the messengers to inform Cetewayo, that before he should think of retiring, all the conditions must be complied with, and the Zulu regiments lay down their arms. Late in the evening several large bodies of the enemy, amounting to some thousands, were noticed moving from the direction of Ulundi, passing by their left flank.
