"I have brought despatches for you, sir," he said as he entered that officer's head-quarters. "Lord Roberts informed me that if, as he supposed, Lord Methuen was still at Boshof, I was to hand them to you, as they relate entirely to the force you are preparing. I have the honour to be one of the commander-in-chief's extra aides-de-camp. My name is Harberton."

"We have all heard of you, Mr. Harberton," the colonel said as he opened the despatches. "Your journey to Kimberley, and your adventurous escape from Pretoria, have made your name familiar to us all."

When he glanced through the despatches he said: "I am glad to see that you are to accompany me till we get to Mafeking. Our arrangements are going on most satisfactorily, and I have no doubt that we shall be in a position to start on the day named. Now, you must be famishing after your ride, though, I suppose, as an old hand, you did not leave Bloemfontein without some provision for the journey. I will tell my orderly to put your horse up at once. Dinner will be ready downstairs in half an hour; they always keep a table for me and my officers."

The dinner at the hotel bore few signs of the long siege. Supplies had been got up, and some of the principal inhabitants had returned, and though at Bloemfontein things had been well managed and comfortable, the style in which meals were served was very inferior to that which had already been attained at Kimberley. Some ten or twelve officers joined Colonel Mahon's party. No allusion whatever was made to the intended expedition, which was kept a profound secret, as even at Kimberley there were many Boer sympathizers, and it was all-important that no rumour of the approaching departure of a large body of horse should be known to them. It was to consist of the Imperial Light Horse, which had arrived from Natal, the Kimberley mounted corps, the Diamond Field Horse, a party of Imperial Yeomanry, and a detachment of the Cape Police, a horse artillery battery with four guns and two machine-guns, a hundred men of the Fusiliers to guard the waggons, fifty-two waggons with ten mules each, and a number of spare horses to take the place of any that might break down. The force amounted in all to twelve hundred men. Not even to the officers who commanded the different corps was their destination made known until the morning of the 4th of May, when the force had ridden out from Kimberley.

Yorke had placed himself altogether under Colonel Mahon's orders, and had looked after many of the details connected with the waggons and provisions. The store of food carried was quite enough to last fourteen days, this being the outside limit of the time that the march was likely to occupy. Once off there was no delay. The mules and the waggons did their work well, and the force moved round to the west of the position of a large body of Boers, who were opposing Methuen's advance by the line of railway, and on the 9th marched into Vryburg, having done a hundred and twenty miles in five days. They halted here for a day to rest the animals, and on the 11th they started again. Hitherto not a shot had been fired. From this point they were watched by the enemy, as their arrival at Vryburg had been at once notified to the Boers, and at Koodoosrand a force was found posted in a strong position in front of them.

Mahon, whose object was not to fight but to relieve Mafeking, moved off to the westward; but here the country was found to be thickly covered with bush, which greatly impeded the progress of the waggons, and presently the enemy, leaving their position, threw themselves across his path. There was a sharp but short encounter, and the Boers were soon in flight. The casualties in killed and wounded on our side were only thirty.

On the 15th the relieving column arrived at a village twenty miles to the west of Mafeking, where, within an hour of their entry, they were joined by Plumer's force, which had just been strengthened by the arrival of four twelve-pounder guns of the Canadian artillery, and a party of Queenslanders.

These troops had performed a marvellous march. On their arrival from Canada and Queensland respectively they had been brought round by ship to Beira, carried by train to the plateau of Rhodesia, from there in vehicles a hundred miles to Buluwayo, then by train over four hundred miles to Ootsi, and had then pushed on on foot for four days over terribly bad roads at the rate of twenty-five miles a day, and had been with Plumer only a few hours.

There was no fear now that they would fail to gain the success they had striven for, as their united force was stronger than that with which Snyman could oppose them. The Boer commander, however, would not retire without one last effort, and he planted his force on a hill which commanded the water supply; but after he had held his ground for an hour, his guns were silenced, and he retired past Mafeking to the trenches on the eastern side. Here, however, the Boers had no rest, for Baden-Powell sallied out with his garrison, and Mahon's guns opened upon them, so that ere long they withdrew and retreated eastward.

Mafeking was free at last! Only six days before, fearing doubtless that relief would come ere long, and possibly hearing that a large cavalry force was nearing Vryburg, the Boers made the most determined attempt to capture Mafeking that had occurred during the siege. Early on the morning of the 12th three hundred volunteers, under the command of Eloff, a grandson of Kruger, crept up to the west of the besiegers' line and reached the native quarters, to which they at once set fire. The barracks of the Protectorate Regiment were held by Hore and some twenty of his men. These, after a stout defence, were compelled to surrender. Two other positions within the line were captured, and had Snyman sent up his support at once, affairs might have ended badly; but this failed to arrive. The telephone and telegraph wires called up the defenders from all parts of the town. These gradually surrounded the positions the Boers had taken, and prevented any reinforcements from reaching them. Knowing that unless aided they must surrender in time, Baden-Powell refused to allow the loss of life that must ensue if the Boers were attacked, and contented himself with preventing them from being reinforced, and at seven in the evening Eloff, finding his position desperate, surrendered.
