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 Willi
