While Buller had established himself firmly upon the left of the Boer position, Pole-Carew had moved forward to the north of the railway line, and French had advanced as far as Swart Kopjes upon the Boer right. These operations on August 26th and 27th were met with some resistance, and entailed a loss of forty or fifty killed and wounded; but it soon became evident that the punishment which they had received at Bergendal had taken the fight out of the Boers, and that this formidable position was to be abandoned as the others had been. On the 28th the burghers were retreating, and Machadodorp, where Kruger had sat so long in his railway carriage, protesting that he would eventually move west and not east, was occupied by Buller. French, moving on a more northerly route, entered Watervalonder with his cavalry upon the same date, driving a small Boer force before him. Amid rain and mist the British columns were pushing rapidly forwards, but still the burghers held together, and still their artillery was uncaptured. The retirement was swift, but it was not yet a rout.
On the 30th the British cavalry were within touch of Nooitgedacht, and saw a glad sight in a long trail of ragged men who were hurrying in their direction along the railway line. They were the British prisoners, eighteen hundred in number, half of whom had been brought from Waterval when Pretoria was captured, while the other half represented the men who had been sent from the south by De Wet, or from the west by De la Rey. Much allowance must be made for the treatment of prisoners by a belligerent who is himself short of food, but nothing can excuse the harshness which the Boers showed to the Colonials who fell into their power, or the callous neglect of the sick prisoners at Waterval. It is a humiliating but an interesting fact that from first to last no fewer than seven thousand of our men passed into their power, all of whom were now recovered save some sixty officers, who had been carried off by them in their flight.
On September 1st Lord Roberts showed his sense of the decisive nature of these recent operations by publishing the proclamation which had been issued as early as July 4th, by which the Transvaal became a portion of the British Empire. On the same day General Buller, who had ceased to advance to the east and retraced his steps as far as Helvetia, began his northerly movement in the direction of Lydenburg, which is nearly fifty miles to the north of the railway line. On that date his force made a march of fourteen miles, which brought them over the Crocodile River to Badfontein. Here, on September 2nd, Buller found that the indomitable Botha was still turning back upon him, for he was faced by so heavy a shell fire, coming from so formidable a position, that he had to be content to wait in front of it until some other column should outflank it. The days of unnecessary frontal attacks were for ever over, and his force, though ready for anything which might be asked of it, had gone through a good deal in the recent operations. Since August 21st they had been under fire almost every day, and their losses, though never great on any one occasion, amounted in the aggregate during that time to 365. They had crossed the Tugela, they had relieved Ladysmith, they had forced Laing\'s Nek, and now it was to them that the honour had fallen of following the enemy into this last fastness. Whatever criticism may be directed against some episodes in the Natal campaign, it must never be forgotten that to Buller and to his men have fallen some of the hardest tasks of the war, and that these tasks have always in the end been successfully carried out. The controversy about the unfortunate message to White, and the memory of the abandoned guns at Colenso, must not lead us to the injustice of ignoring all that is to be set to the credit account.
On September 3rd Lord Roberts, finding how strong a position faced Buller, despatched Ian Hamilton with a force to turn it upon the right. Brocklehurst\'s brigade of cavalry joined Hamilton in his advance. On the 4th he was within signalling distance of Buller, and on the right rear of the Boer position. The occupation of a mountain called Zwaggenhoek would establish Hamilton firmly, and the difficult task of seizing it at night was committed to Colonel Douglas and his fine regiment of Royal Scots. It was Spion Kop over again, but with a happier ending. At break of day the Boers discovered that their position had been rendered untenable and withdrew, leaving the road to Lydenburg clear to Buller. Hamilton and he occupied the town upon the 6th. The Boers had split into two parties, the larger one with the guns falling back upon Kruger\'s Post, and the others retiring to Pilgrim\'s Rest. Amid cloud-girt peaks and hardly passable ravines the two long-enduring armies still wrestled for the final mastery.
To the north-east of Lydenburg, between that town and Spitzkop, there is a formidable ridge called the Mauchberg, and here again the enemy were found to be standing at bay. They were even better than their word, for they had always said that they would make their last stand at Lydenburg, and now they were making one beyond it. But the resistance was weakening. Even this fine position could not be held against the rush of the three regiments, the Devons, the Royal Irish, and the Royal Scots, who were let loose upon it. The artillery supported the attack admirably. \'They did nobly,\' said one who led the advance. \'It is impossible to overrate the value of their support. They ceased also exactly at the right moment. One more shell would have hit us.\' Mountain mists saved the defeated burghers from a close pursuit, but the hills were carried. The British losses on this day, September 8th, were thirteen killed and twenty-five wounded; but of these thirty-eight no less than half were accounted for by one of those strange malignant freaks which can neither be foreseen nor prevented. A shrapnel shell, fired at an incredible distance, burst right over the Volunteer Company of the Gordons who were marching in column. Nineteen men fell, but it is worth recording that, smitten so suddenly and so terribly, the gallant Volunteers continued to advance as steadily as before this misfortune befell them. On the 9th Buller was still pushing forward to Spitzkop, his guns and the 1st Rifles overpowering a weak rearguard resistance of the Boers. On the 10th he had reached Klipgat, which is halfway between the Mauchberg and Spitzkop. So close was the pursuit that the Boers, as they streamed through the passes, flung thirteen of their ammunition wagons over the cliffs to prevent them from falling into the hands of the British horsemen. At one period it looked as if the gallant Boer guns had waited too long in covering the retreat of the burghers. Strathcona\'s Horse pressed closely upon them. The situation was saved by the extreme coolness and audacity of the Boer gunners. \'When the cavalry were barely half a mile behind the rear gun\' says an eye-witness \'and we regarded its capture as certain, the LEADING Long Tom deliberately turned to bay and opened with case shot at the pursuers streaming down the hill in single file over the head of his brother gun. It was a magnificent coup, and perfectly successful. The cavalry had to retire, leaving a few men wounded, and by the time our heavy guns had arrived both Long Toms had got clean away.\' But the Boer riflemen would no longer stand. Demoralised after their magnificent struggle of eleven months the burghers were now a beaten and disorderly rabble flying wildly to the eastward, and only held together by the knowledge that in their desperate situation there was more comfort and safety in numbers. The war seemed to be swiftly approaching its close. On the 15th Buller occupied Spitzkop in the north, capturing a quantity of stores, while on the 14th French took Barberton in the south, releasing all the remaining British prisoners and taking possession of forty locomotives, which do not appear to have been injured by the enemy. Meanwhile Pole-Carew had worked along the railway line, and had occupied Kaapmuiden, which was the junction where the Barberton line joins that to Lourenco Marques. Ian Hamilton\'s force, after the taking of Lydenburg and the action which followed, turned back, leaving Buller to go his own way, and reached Komatipoort on September 24th, having marched since September 9th without a halt through a most difficult country.
