Lord Chelmsford also left Durban, and proceeded to Maritzburg: thence he travelled on to Dundee and Utrecht, and then on to Wood's camp at Kambula, where he arrived on May 3rd. The main features of the plans for the fresh campaign were, roughly speaking, as follows. Two principal forces, operating from separate bases, the one at Utrecht, and the other at Durban, were to be held in communication by Wood, with a flying column, and by Marshall's cavalry. The common objective of these four columns was to be Ulundi, the king's chief kraal. To keep up communications with these two flanks, to make occasional raids and dashes forward into the enemy's country, and at any favourable moment to convert a feigned into a real rush upon Ulundi, Wood was to retain his separate and independent command. His force, however, was to be largely reinforced, and more troops, if possible cavalry, sent to him. The first column, as it was called, under Major-General Hope Crealock, C.B., was to advance rapidly by the coast road, having as its respective bases of operations Durban, Fort Pearson, and Ginghilovo. The other column, under the personal command of Lord Chelmsford, with Utrecht as its principal base on the extreme north, was to move also upon Ulundi. Meanwhile Wood, who had been strongly reinforced, while nominally forming part of Lord Chelmsford's headquarter division, practically retained his independent command, and formed a sort of flying column connecting the two flanks with each other. No. 1 division, then preparing for advance from the Lower Tugela, consisted of three fine brigades. The First Brigade, commanded by Colonel Pearson of Ekowe fame, consisted of the 3rd Buffs, the 88th Connaught Rangers, and the 99th Foot, each of these corps averaging 800 bayonets. The Second Brigade, under the command of Colonel Pemberton, had in it the 57th, the 3rd battalion 60th Rifles, and the 91st Highlanders; while the Third Brigade, under Colonel Law, had a battery of Royal Artillery, the Naval Brigade from the "Shah" and "Boadicea," at least 800 strong, with four guns and two Gatlings, Barrow's Horse, and a Native Contingent. Before the final advance was made, it was determined that posts of communication should be established at the Amatikula and the Inyezani rivers, over which pontoon bridges were to be constructed. Meanwhile for temporary purposes there was constructed over the Amatikula stream a cask bridge, by laying two slings, with eye splices at one end, parallel to each other, at a distance in proportion to the length of the casks. On these ropes were placed as many casks as required, bungs uppermost, and side by side. Across the upper surface of the barrels balks were laid parallel to each other, and the ends of the slings at each end of the row of casks were brought up and fastened to the ends of the balks. A small rope with an eye at each end was fastened to each sling between each pair of casks.
