Before describing this attempt it would be well to trace the progress of the eastern invasion (Kritzinger's), a movement which may be treated rapidly, since it led to no particular military result at that time, though it lasted long after Hertzog's force had been finally dissipated. Several small columns, those of Williams, Byng, Grenfell, and Lowe, all under the direction of Haig, were organised to drive back these commandos; but so nimble were the invaders, so vast the distances and so broken the country, that it was seldom that the forces came into contact. The operations were conducted over a portion of the Colony which is strongly Dutch in sympathy, and the enemy, though they do not appear to have obtained any large number of recruits, were able to gather stores, horses, and information wherever they went.

When last mentioned Kritzinger's men had crossed the railway north of Rosmead on December 30th, and held up a train containing some Colonial troops. From then onwards a part of them remained in the Middelburg and Graaf-Reinet districts, while part moved towards the south. On January 11th there was a sharp skirmish near Murraysburg, in which Byng's column was engaged, at the cost of twenty casualties, all of Brabant's or the South African Light Horse. On the 16th a very rapid movement towards the south began. On that date Boers appeared at Aberdeen, and on the 18th at Willowmore, having covered seventy miles in two days. Their long, thin line was shredded out over 150 miles, and from Maraisburg, in the north, to Uniondale, which is only thirty miles from the coast, there was rumour of their presence. In this wild district and in that of Oudtshoorn the Boer vanguard flitted in and out of the hills, Haig's column striving hard to bring them to an action. So well-informed were the invaders that they were always able to avoid the British concentrations, while if a British outpost or patrol was left exposed it was fortunate if it escaped disaster. On February 6th a small body of twenty-five of the 7th King's Dragoon Guards and of the West Australians, under Captain Oliver, were overwhelmed at Klipplaat, after a very fine defence, in which they held their own against 200 Boers for eight hours, and lost nearly fifty per cent of their number. On the 12th a patrol of yeomanry was surprised and taken near Willowmore.

The coming of De Wet had evidently been the signal for all the Boer raiders to concentrate, for in the second week of February Kritzinger also began to fall back, as Hertzog had done in the west, followed closely by the British columns. He did not, however, actually join De Wet, and his evacuation of the country was never complete, as was the case with Hertzog's force. On the 19th Kritzinger was at Bethesda, with Gorringe and Lowe at his heels. On the 23rd an important railway bridge at Fish River, north of Cradock, was attacked, but the attempt was foiled by the resistance of a handful of Cape Police and Lancasters. On March 6th a party of Boers occupied the village of Pearston, capturing a few rifles and some ammunition. On the same date there was a skirmish between Colonel Parsons's column and a party of the enemy to the north of Aberdeen. The main body of the invading force appears to have been lurking in this neighbourhood, as they were able upon April 7th to cut off a strong British patrol, consisting of a hundred Lancers and Yeomanry, seventy-five of whom remained as temporary prisoners in the hands of the enemy. With this success we may for the time leave Kritzinger and his lieutenant, Scheepers, who commanded that portion of his force which had penetrated to the south of the Colony.

The two invasions which have been here described, that of Hertzog in the west and of Kritzinger in the midlands, would appear in themselves to be unimportant military operations, since they were carried out by small bodies of men whose policy was rather to avoid than to overcome resistance. Their importance, however, is due to the fact that they were really the forerunners of a more important incursion upon the part of De Wet. The object of these two bands of raiders was to spy out the land, so that on the arrival of the main body all might be ready for that general rising of their kinsmen in the Colony which was the last chance, not of winning, but of prolonging the war. It must be confessed that, however much their reason might approve of the Government under which they lived, the sentiment of the Cape Dutch had been cruelly, though unavoidably, hurt in the course of the war. The appearance of so popular a leader as De Wet with a few thousand veterans in the very heart of their country might have stretched their patience to the breaking-point. Inflamed, as they were, by that racial hatred which had always smouldered, and had now been fanned into a blaze by the speeches of their leaders and by the fictions of their newspapers, they were ripe for mischief, while they had before their eyes an object-lesson of the impotence of our military system in those small bands who had kept the country in a ferment for so long. All was propitious, therefore, for the attempt which Steyn and De Wet were about to make to carry the war into the enemy's country.

We last saw De Wet when, after a long chase, he had been headed back from the Orange River, and, winning clear from Knox's pursuit, had in the third week of December passed successfully through the British cordon between Thabanchu and Ladybrand. Thence he made his way to Senekal, and proceeded, in spite of the shaking which he had had, to recruit and recuperate in the amazing way which a Boer army has. There is no force so easy to drive and so difficult to destroy. The British columns still kept in touch with De Wet, but found it impossible to bring him to an action in the difficult district to which he had withdrawn. His force had split up into numerous smaller bodies, capable of reuniting at a signal from their leader. These scattered bodies, mobile as ever, vanished if seriously attacked, while keenly on the alert to pounce upon any British force which might be overpowered before assistance could arrive. Such an opportunity came to the commando led by Philip Botha, and the result was another petty reverse to the British arms.

Upon January 3rd Colonel White's small column was pushing north, in co-operation with those of Knox, Pilcher, and the others. Upon that date it had reached a point just north of Lindley, a district which has never been a fortunate one for the invaders. A patrol of Kitchener' s newly raised bodyguard, under Colonel Laing, 120 strong, was sent forward to reconnoitre upon the road from Lindley to Reitz.

The scouting appears to have been negligently done, there being only two men out upon each flank. The little force walked into one of those horse-shoe positions which the Boers love, and learned by a sudden volley from a kraal upon their right that the enemy was present in strength. On attempting to withdraw it was instantly evident that the Boers were on all sides and in the rear with a force which numbered at least five to one. The camp of the main column was only four miles away, however, and the bodyguard, having sent messages of their precarious position, did all they could to make a defence until help could reach them. Colonel Laing had fallen, shot through the heart, but found a gallant successor in young Nairne, the adjutant. Part of the force had thrown themselves, under Nairne and Milne, into a donga, which gave some shelter from the sleet of bullets. The others, under Captain Butters, held on to a ruined kraal. The Boers pushed the attack very rapidly, however, and were soon able with their superior numbers to send a raking fire down the donga, which made it a perfect death-trap. Still hoping that the laggard reinforcements would come up, the survivors held desperately on; but both in the kraal and in the donga their numbers were from minute to minute diminishing. There was no formal surrender and no white flag, for, when fifty per cent of the British were down, the Boers closed in swiftly and rushed the position. Philip Botha, the brother of the commandant, who led the Boers, behaved with courtesy and humanity to the survivors; but many of the wounds were inflicted with those horrible explosive and expansive missiles, the use of which among civilised combatants should now and always be a capital offence. To disable one's adversary is a painful necessity of warfare, but nothing can excuse the wilful mutilation and torture which is inflicted by these brutal devices.

'How many of you are there?' asked Botha. 'A hundred,' said an officer. 'It is not true. There are one hundred and twenty. I counted you as you came along.' The answer of the Boer leader shows how carefully the small force had been nursed until it was in an impossible position. The margin was a narrow one, however, for within fifteen minutes of the disaster White's guns were at work. There may be some question as to whether the rescuing force could have come sooner, but there can be none as to the resistance of the bodyguard. They held out to the last cartridge. Colonel Laing and three officers with sixteen men were killed, four officers and twenty-two men were wounded. The high proportion of fatal casualties can only be explained by the deadly character of the Boer bullets. Hardly a single horse of the bodyguard was left unwounded, and the profit to the victors, since they were unable to carry away their prisoners, lay entirely in the captured rifles. It is worthy of record that the British wounded were despatched to Heilbron without guard through the Boer forces. That they arrived there unmolested is due to the forbearance of the enemy and to the tact and energy of Surgeon-Captain Porter, who commanded the convoy.

Encouraged by this small success, and stimulated by the news that Hertzog and Kritzinger had succeeded in penetrating the Colony without disaster, De Wet now prepared to follow them. British scouts to the north of Kroonstad reported horsemen riding south and east, sometimes alone, sometimes in small parties. They were recruits going to swell the forces of De Wet. On January 23rd five hundred men crossed the line, journeying in the same direction. Before the end of the month, having gathered together about 2500 men with fresh horses at the Doornberg, twenty miles north of Winburg, the Boer leader was ready for one of his lightning treks once more. On January 28th he broke south through the British net, which appears to have had more meshes than cord. Passing the Bloemfontein-Ladybrand line at Israel Poort he swept southwards, with British columns still wearily trailing behind him, like honest bulldogs panting after a greyhound.

Before following him upon this new venture it is necessary to say a few words about that peace movement in the Boer States to which some allusion has already been made. On December 20th Lord Kitchener had issued a proclamation which was intended to have the effect of affording protection to those burghers who desired to cease fighting, but who were unable to do so without incurring the enmity of their irreconcilable brethren. 'It is hereby notified,' said the document, 'to all burghers that if after this date they voluntarily surrender they will be allowed to live with their families in Government laagers until such time as the guerilla warfare now being carried on will admit of their returning safely to their homes. All stock and property brought in at the time of the surrender of such burghers will be respected and paid for if requisitioned.' This wise and liberal offer was sedulously concealed from their men by the leaders of the fighting commandos, but was largely taken advantage of by those Boers to whom it was conveyed. Boer refugee camps were formed at Pretoria, Johannesburg, Kroonstad, Bloemfontein, Warrenton; and other points, to which by degrees the whole civil population came to be transferred. It was the reconcentrado system of Cuba over again, with the essential difference that the guests of the British Government were well fed and well treated during their detention. Within a few months the camps had 50,000 inmates.
