[CHAPTER XIV]
The Taming of the Transvaal
The course of the war north of the Vaal after the battle of Diamond Hill up to the date of Lord Roberts' arrival at Belfast seven weeks later was tortuous and difficult. The main Army changed front as soon as Pretoria was reached and faced to the east in the direction of the retreating Transvaal Government. Its line of communication became a prolongation of its front; its left flank towards the north was open; and on its rear was the unsubdued country west of the capital in the direction of Mafeking and Vryburg.
Through this district, which is intersected by ranges running generally east and west, and which contains some towns of importance, the troops set free by the relief of Mafeking advanced in two columns towards Pretoria and Johannesburg. The southern column was Hunter's Xth Division, which after easily occupying Potchefstroom and Krugersdorp, passed through Johannesburg, and on Hunter's being sent into the Free State was broken up at Heidelberg. The northern column, under Baden-Powell, occupied Rustenburg and met with little opposition during the month of June. It was intended by Lord Roberts, if all went well, that this column should eventually take up a position on the Pietersburg railway, north of Pretoria, which was unprotected in that direction.
The inactivity of the Boers seemed to show that they had really lost heart, and that an awakening such as that which came a few weeks after the entry into Bloemfontein was improbable. Earlier in the month of June there had been negotiations for peace, not only between subordinate leaders in the Free State and Natal, but also between the two Commanders-in-Chief in Pretoria; and although they were broken off, the fact that they had occurred made the silence more significant and gave hope that the enemy was reconsidering his position.
The illusion was soon dispelled. Whether owing to the natural resilience of the Boer character after a brief phase of doubt, or to the news of De Wet's successful attacks on the railway in the Free State, the smouldering fires broke out anew early in July. Delarey, who had checked French at Diamond Hill, came out of the east to quicken the west; the baffled burghers of Snyman, released from the siege of Mafeking, were trickling vaguely into the district; a force under Grobler of Waterberg was reported north of Pretoria; an incursion was made across the Vaal from the Free State; and commandos appeared south of the Magaliesberg near Olifant's Nek and Commando Nek, thus threatening the movements of Baden-Powell, who was operating north of the range and who had occupied Commando Nek and the adjacent Zilikat's Nek on July 2, leaving only a small force at Rustenburg. Five days later the Boers failed in an attempt to recapture the town, which was saved by a detachment of the Rhodesian Field Force.
This force, which was under the command of Sir F. Carrington, was composed mainly of mounted contingents from the Colonies. It had been raised a few months before at the instance of the British South Africa Company to hold the northern frontier of the Transvaal, which after Plumer's departure for the south was unguarded, and to deny Rhodesia to the Boers should they attempt to break out northwards. It was from the first under a sort of dual control which militated against its efficiency. The Company made the arrangements for its enrolment and equipment, while the War Office provided the staff. It was in difficulties from the first. By a somewhat strained interpretation of a treaty between Great Britain and Portugal, and after some weeks of diplomatic discussion and in spite of a protest naturally made by the Transvaal Government, the Rhodesian Field Force was permitted to land on Portuguese territory at Beira in April and to move up country. Its advance was further delayed by a break of gauge on the railway between Beira and Buluwayo; it was pulled hither and thither, and was never able to co-operate effectively with the general operations. It was moved in driblets, and some details did not reach Buluwayo until September. A portion of it came along the Western line, and Rustenburg was saved by the Imperial Bushmen. At the end of the year it was disbanded.
On July 11 three blows were struck by the Boers with success. The attempt on Rustenburg drew back Baden-Powell, whose place at Zilikat's and Commando Neks was taken by a regiment of regular cavalry which happened to be passing that way. As it was required elsewhere, a body of infantry was sent out from Pretoria to take over the Neks, and on the night of July 10 Zilikat's Nek was held by three companies and a squadron. Next day, after a struggle which lasted throughout the day, it was captured by Delarey, and two guns and nearly 200 prisoners of war fell into his hands. The disaster, the first of its kind in the Transvaal, was due to two causes. The British force actually at the Nek was insufficient to hold it; and the main body of the cavalry stood aloof. The latter was no doubt in a dubious position. It was under orders, which were brought by the infantry relief, to meet Smith-Dorrien nearly twenty-five miles away on July 11; and when the enemy was seen occupying a strong position on the Nek, it assumed that assistance would be of no avail, and beyond a short artillery bombardment nothing was done. Even the squadron holding Commando Nek was ordered to retire at midday. A relieving force was sent out from Pretoria, but it arrived too late to avert the disaster.
The cavalry thus delayed was intended to reinforce a column under Smith-Dorrien, who had come up into the Transvaal with Ian Hamilton's column, and who was marching from Krugersdorp to take off the pressure from the south on Baden-Powell at Rustenburg; Olifant's Nek, over which the road to the town passed, being in the possession of the Boers. On July 11, when Smith-Dorrien had marched about ten miles from his starting point, he met a commando at Dwarsvlei, which was so well handled that not only was he compelled to retire on Krugersdorp, but also had much difficulty in bringing away his guns. The failure was chiefly due to the non-appearance of the cavalry, without which he did not feel himself justified in standing up to the enemy.
