The advance of Barton's brigade on the 12th had been unopposed, and during the two following days the remainder of the Natal army was moved up to the north-west of Chieveley, and collected in a large camp on the western side of the railway, near Doornkop Spruit. It was, of course, impossible to conceal this movement from the Boer commander on the heights north of the river.
Sir Redvers, Dec. 14th, issues his orders for attack.
On the afternoon of the 14th Sir Redvers Buller, who had spent the earlier part of that day in examining the enemy's positions through a telescope, assembled his subordinate commanders and their staffs, to communicate, and personally explain to them his instructions for the operations of the following day. His plan was to try to force the passage of the river by direct attack. The written orders signed by the Assistant Adjutant-General of the 2nd division were not issued until late in the evening, and did not reach the Brigadiers until about midnight. They will be found at the end of this chapter. The first paragraph of these orders appears to imply that the enemy's entrenchments were limited to the Colenso kopjes; at any rate, it is clear that the extent and strength of the Boer entrenchments westward were not then known. These kopjes were selected as the object of the main attack, and this duty was assigned to the 2nd brigade (Hildyard's). The crossing of this brigade "by the iron bridge," that is, the Bulwer bridge, was to be prepared by the fire of No. 1 brigade division Royal Field artillery, less one field battery which was replaced by six Naval guns. This artillery preparation was to be assisted by the fire of the remaining Naval guns, two 4·7-in. and four 12-pounders,[224] and by that of the 2nd brigade division, which was instructed to "take up a position whence it can enfilade the kopjes north of the iron bridge." This latter artillery unit was also to "act on any orders it receives from Major-General Hart."
Orders for Hart.
To Major-General Hart's brigade (the 5th) had been assigned a special rôle; it was ordered to cross the river at the "Bridle Drift, immediately west of the junction of Doornkop Spruit and the Tugela," and subsequently to move down the left bank of the river towards the Colenso kopjes. The Commander-in-Chief hoped that this supplementary crossing would be accomplished before the central attack was delivered, and that the 5th brigade would thus be able to render substantial assistance in the assault on the bridge; even if General Hart did not succeed in passing his battalions across the river, Sir Redvers anticipated that he would, in any case, be able at least to cover the left flank of the main attack by engaging the enemy on the western side.[225]
Orders for right flank.
The right flank of the main attack was to be guarded by the 6th brigade (Barton's), less half a battalion on baggage guard duty, and the mounted brigade. Lord Dundonald, who was in command of the latter unit (the total effective strength of which was about 1,800), was instructed to detail 500 men to watch the right flank of the enemy, and 300 to cover Buller's right flank and protect the baggage. and for watching left flank. With the remainder of his brigade, and a battery detached from No. 1 brigade division, "he will," said the order, "cover the right flank of the general movement and will endeavour to take up a position on Hlangwhane Hill, whence he will enfilade the kopjes north of the iron bridge."
