Thus the westward movement, instead of being a helpful operation at large in support of the main advance, was whittled down to the turning of Laing's Nek. Between Botha's Pass and Laing's Nek the dominant contours roughly assume the outline of a sickle and its handle, the Pass being at the end of the handle and the Nek near the point of the blade. Within the curve of the blade stands the high Inkwelo Mountain facing Majuba Hill, and at the upper end of the handle is a mountain of less elevation called Inkweloane. The Ingogo River, which rises near the Pass, is flanked on its right bank by Van Wyk's Hill, which commands the eastern approach to the Pass, and on its left bank by Spitz Kop, a detached hill of the main range.
Inkwelo had been held for some days by a portion of Clery's Division. The Boers occupied Spitz Kop and the ridge from Inkweloane to the Pass and a short section beyond it, but their line was thin. The Vryheid and Utrecht affairs had deceived them into the belief that an eastward turning movement was in contemplation. On June 6 Van Wyk's Hill was occupied by Hildyard and held against the enemy on Spitz Kop, who attempted to dislodge him; and by the following morning artillery had been brought up, and the Pass and the enemy's position on the adjacent crestline were commanded. These on June 8 were carried by an infantry movement in echelon with loss of two men killed. Spitz Kop offered no resistance. A fusillade broke out on Inkweloane, but Dundonald's brigade soon quenched it by a determined ascent up alpine slopes to the crestline As at Helpmakaar the enemy set fire to the grass and passed away behind a veil of smoke.
The capture of Botha's Pass was an affair which did credit to Buller. It showed that since Colenso he had learnt how to use artillery, and his disposition of his guns was admirable. They rendered the enemy's position untenable and left little but hard climbing to the infantry. It can hardly be termed a battle, it was rather an autumn manoeuvre engagement, conducted on Lord Roberts' principles. A very important position was won and the enemy driven back with scarcely the shedding of a drop of blood on either side. Hildyard was in executive charge of the operations.
Thus, after eight months' fighting, the main body of the Natal Army was at last in bivouac in the enemy's country. Buller had taken Botha's Pass with three infantry and two cavalry brigades; and with these he made for his next objective, the town of Volksrust in the Transvaal, a few miles north of Laing's Nek, which Clery at Ingogo was watching from the south. Lyttelton was posted on the left bank of the Buffalo watching the right flank of the advance.
Buller's operations in the Free State lasted two days only. On June 10 he engaged a small body of the retreating enemy and entered the Transvaal. In front of him was the Versamelberg, a spur of the Drakensberg, over which the road from Vrede to Volksrust passes at Alleman's Nek, where 2,000 Boers with four guns had taken up a very strong position. The road rises to the Nek between heights, and the initial movements of the attack had to be made across two miles of open veld. The burghers had not had the time, or did not think it necessary, to strengthen the position artificially, but they were observed throwing up some entrenchments when Buller approached.
His bivouac on June 10 was at the Gansvlei Spruit on the Transvaal-Free State border, and next day at dawn he resumed his march on Volksrust. No serious opposition was encountered until early in the afternoon, when Dundonald, who was operating on the right front, came under artillery fire from the Nek. The infantry, whose left flank was watched by Brocklehurst with a cavalry brigade, was then ordered to advance, the objective of the 2nd Brigade under E. Hamilton being the ridge on the left of the Nek, and that of the 10th Brigade under Talbot Coke the ridges on the right of it, the 11th Brigade under Wynne being kept in reserve.
The advance was made under a heavy and worrying but not very effective fire from each section of the ridge. The key of the position proved to be a conical hill on the right of the road at the entrance to the Nek. The Dorsets of Coke's brigade gallantly climbed the slopes, and aided by artillery fire carried it with the bayonet. The fight, however, was far from ended. The Boers beyond remained until the shells which had been pouring on the conical hill followed them to the crestline. Then again the Dorsets threw themselves upon the enemy, and by sunset the heights on the right of the Nek were in possession of Coke. Almost simultaneously E. Hamilton established himself on the left of it. The resistance offered to Dundonald on the right flank was more effective; and as between him and his immediate opponents the day waned upon an uncertain issue. He had driven them out of successive positions though not actually off the ridge; but the occupation of the Nek made further opposition useless and they withdrew during the night.
The capture of Alleman's Nek rendered Laing's Nek untenable, and Clery closing up from Ingogo next day found it abandoned. The enemy had evacuated the whole of the Majuba-Laing's Nek-Pougwana position, leaving scarcely so much as a wagon behind him, and was retreating northwards. The westward turning movement was tactically a success but strategically a failure. With three brigades of mounted troops under his orders, including some regiments of regular cavalry which were lying idle at Ladysmith and elsewhere, Buller made no attempt to cut off the retreating Boers. A daring raid, such as had been twice made by French on the Modder four months before, concurrently with the Botha's Pass operations would have had a good chance of crushing C. Botha; and Brockleburst's cavalry, which during the attack on the Nek was working somewhat widely on the left flank, might well have been sent to bar the way. The ponderous movements of Buller were in strange contrast to the activity of his ally Lord Roberts. The Natal Army made its way through the country like an elephant trampling through a sugar-cane plantation.
On June 13 Buller entered Volksrust and next day established his Head Quarters at Laing's Nek. Wakkerstroom, a town which threatened his right flank, surrendered pro formâ to Lyttelton on June 13, and again to Hildyard four days later; and no doubt would have been equally ready to accommodate itself to the wishes of any other column sent to it, but after each surrender it reasserted itself, and Buller was obliged to leave it in charge of the commandos.
With the occupation of Laing's Nek the Natal campaign, which had lasted eight months, came to an end, and Buller, having left a strong force under Lyttelton in charge of Natal, passed up the railway to Heidelberg; where on July 4 he for the first time came into physical touch with the main Army under Lord Roberts. By a curious coincidence he here met Hart's Brigade of the Xth Division, which had left his command three months previously at Ladysmith, and which had in the meantime marched up from Kimberley.
