Fortunately the good sense of the assembly prevailed, and the agitation, though bitter, remained within those wide limits which a British constitution permits. Three resolutions were passed, one asking that the war be ended, a second that the independence of the Republics be restored, and a third protesting against the actions of Sir Alfred Milner. A deputation which carried these to the Governor received a courteous but an uncompromising reply. Sir Alfred Milner pointed out that the Home Government, all the great Colonies, and half the Cape were unanimous in their policy, and that it was folly to imagine that it could be reversed on account of a local agitation. All were agreed in the desire to end the war, but the last way of bringing this about was by encouraging desperate men to go on fighting in a hopeless cause. Such was the general nature of the Governor's reply, which was, as might be expected, entirely endorsed by the British Government and people.
Had De Wet, in the operations which have already been described, evaded Charles Knox and crossed the Orange River, his entrance into the Colony would have been synchronous with the congress at Worcester, and the situation would have become more acute. This peril was fortunately averted. The agitation in the Colony suggested to the Boer leaders, however, that here was an untouched recruiting ground, and that small mobile invading parties might gather strength and become formidable. It was obvious, also, that by enlarging the field of operations the difficulties of the British Commander-in-chief would be very much increased, and the pressure upon the Boer guerillas in the Republics relaxed. Therefore, in spite of De Wet's failure to penetrate the Colony, several smaller bands under less-known leaders were despatched over the Orange River. With the help of the information and the supplies furnished by the local farmers, these bands wandered for many months over the great expanse of the Colony, taking refuge, when hard pressed, among the mountain ranges. They moved swiftly about, obtaining remounts from their friends, and avoiding everything in the nature of an action, save when the odds were overwhelmingly in their favour. Numerous small posts or patrols cut off, many skirmishes, and one or two railway smashes were the fruits of this invasion, which lasted till the end of the war, and kept the Colony in an extreme state of unrest during that period. A short account must be given here of the movement and exploits of these hostile bands, avoiding, as far as possible, that catalogue of obscure 'fonteins' and 'kops' which mark their progress.
The invasion was conducted by two main bodies, which shed off numerous small raiding parties. Of these two, one operated on the western side of the Colony, reaching the sea-coast in the Clanwilliam district, and attaining a point which is less than a hundred miles from Cape Town. The other penetrated even more deeply down the centre of the Colony, reaching almost to the sea in the Mossel Bay direction. Yet the incursion, although so far-reaching, had small effect, since the invaders held nothing save the ground on which they stood, and won their way, not by victory, but by the avoidance of danger. Some recruits were won to their cause, but they do not seem at that time to have been more than a few hundreds in number, and to have been drawn for the most part from the classes of the community which had least to lose and least to offer.
The Western Boers were commanded by Judge Hertzog of the Free State, having with him Brand, the son of the former president, and about twelve hundred well-mounted men. Crossing the Orange River at Sand Drift, north of Colesberg, upon December 16th, they paused at Kameelfontein to gather up a small post of thirty yeomen and guardsmen under Lieutenant Fletcher, the wellknown oar. Meeting with a stout resistance, and learning that British forces were already converging upon them, they abandoned the attack, and turning away from Colesberg they headed west, cutting the railway line twenty miles to the north of De Aar. On the 22nd they occupied Britstown, which is eighty miles inside the border, and on the same day they captured a small body of yeomanry who had been following them. These prisoners were released again some days later. Taking a sweep round towards Prieska and Strydenburg, they pushed south again. At the end of the year Hertzog's column was 150 miles deep in the Colony, sweeping through the barren and thinly-inhabited western lands, heading apparently for Fraserburg and Beaufort West.
The second column was commanded by Kritzinger, a burgher of Zastron, in the Orange River Colony. His force was about 800 strong. Crossing the border at Rhenoster Hoek upon December 16th, they pushed for Burghersdorp, but were headed off by a British column. Passing through Venterstad, they made for Steynsberg, fighting two indecisive skirmishes with small British forces. The end of the year saw them crossing the rail road at Sherburne, north of Rosmead Junction, where they captured a train as they passed, containing some Colonial troops. At this time they were a hundred miles inside the Colony, and nearly three hundred from Hertzog's western column.
In the meantime Lord Kitchener, who had descended for a few days to De Aar, had shown great energy in organising small mobile columns which should follow and, if possible, destroy the invaders. Martial law was proclaimed in the parts of the Colony affected, and as the invaders came further south the utmost enthusiasm was shown by the loyalists, who formed themselves everywhere into town guards. The existing Colonial regiments, such as Brabant's, the Imperial and South African Light Horse—Thorneycroft's, Rimington's, and the others—had already been brought up to strength again, and now two new regiments were added, Kitchener's Bodyguard and Kitchener's Fighting Scouts, the latter being raised by Johann Colenbrander, who had made a name for himself in the Rhodesian wars. At this period of the war between twenty and thirty thousand Cape colonists were under arms. Many of these were untrained levies, but they possessed the martial spirit of the race, and they set free more seasoned troops for other duties.
It will be most convenient and least obscure to follow the movements of the western force (Hertzog's), and afterwards to consider those of the eastern (Kritzinger's). The opening of the year saw the mobile column of Free Staters 150 miles over the border, pushing swiftly south over the barren surface of the Karoo. It is a country of scattered farms and scanty population; desolate plains curving upwards until they rise into still more desolate mountain ranges. Moving in a very loose formation over a wide front, the Boers swept southwards. On or about January 4th they took possession of the small town of Calvinia, which remained their headquarters for more than a month. From this point their roving bands made their way as far as the seacoast in the Clanwilliam direction, for they expected at Lambert's Bay to meet with a vessel with mercenaries and guns from Europe. They pushed their outposts also as far as Sutherland and Beaufort West in the south. On January 15th strange horsemen were seen hovering about the line at Touws River, and the citizens of Cape Town learned with amazement that the war had been carried to within a hundred miles of their own doors.
Whilst the Boers were making this daring raid a force consisting of several mobile columns was being organised by General Settle to arrest and finally to repel the western invasion. The larger body was under the command of Colonel De Lisle, an officer who brought to the operations of war the same energy and thoroughness with which he had made the polo team of an infantry regiment the champions of the whole British Army. His troops consisted of the 6th Mounted Infantry, the New South Wales Mounted Infantry, the Irish Yeomanry, a section of R battery R.H.A., and a pom-pom. With this small but mobile and hardy force he threw himself in front of Hertzog's line of advance. On January 13th he occupied Piquetburg, eighty miles south of the Boer headquarters. On the 23rd he was at Clanwilliam, fifty miles south-west of them. To his right were three other small British columns under Bethune, Thorneycroft, and Henniker, the latter resting upon the railway at Matjesfontein, and the whole line extending over 120 miles—barring the southern path to the invaders.
Though Hertzog at Calvinia and De Lisle at Clanwilliam were only fifty miles apart, the intervening country is among the most broken and mountainous in South Africa. Between the two points, and nearer to De Lisle than to Hertzog, flows the Doorn River. The Boers advancing from Calvinia came into touch with the British scouts at this point, and drove them in upon January 21st. On the 28th De Lisle, having been reinforced by Bethune's column, was able at last to take the initiative. Bethune's force consisted mainly of Colonials, and included Kitchener's Fighting Scouts, the Cape Mounted Police, Cape Mounted Rifles, Brabant's Horse, and the Diamond Field Horse. At the end of January the united forces of Bethune and of De Lisle advanced upon Calvinia. The difficulties lay rather in the impassable country than in the resistance of an enemy who was determined to refuse battle. On February 6th, after a fine march, De Lisle and his men took possession of Calvinia, which had been abandoned by the Boers. It is painful to add that during the month that they had held the town they appear to have behaved with great harshness, especially to the kaffirs. The flogging and shooting of a coloured man named Esan forms one more incident in the dark story of the Boer and his relations to the native.
The British were now sweeping north on a very extended front. Colenbrander had occupied Van Rhyns Dorp, to the east of Calvinia, while Bethune's force was operating to the west of it. De Lisle hardly halted at Calvinia, but pushed onwards to Williston, covering seventy-two miles of broken country in forty-eight hours, one of the most amazing performances of the war. Quick as he was, the Boers were quicker still, and during his northward march he does not appear to have actually come into contact with them. Their line of retreat lay through Carnarvon, and upon February 22nd they crossed the railway line to the north of De Aar, and joined upon February 26th the new invading force under De Wet, who had now crossed the Orange River. De Lisle, who had passed over five hundred miles of barren country since he advanced from Piquetburg, made for the railway at Victoria West, and was despatched from that place on February 22nd to the scene of action in the north. From all parts Boer and Briton were concentrating in their effort to aid or to repel the inroad of the famous guerilla.
