To the very end the better intelligence and the higher mobility seem to have remained upon the side of the Boers, who could always force a fight when they wished and escape when they wished. Occasionally, however, they forced one at the wrong time, as in the instance which I am about to describe.
Hamilton had planned a drive to cover the southern portion of De la Rey's country, and for this purpose, with Hartebeestefontein for his centre, he was manoeuvring his columns so as to swing them into line and then sweep back towards Klerksdorp. Kekewich, Rawlinson, and Walter Kitchener were all manoeuvring for this purpose. The Boers, however, game to the last, although they were aware that their leaders had gone in to treat, and that peace was probably due within a few days, determined to have one last gallant fall with a British column. The forces of Kekewich were the farthest to the westward, and also, as the burghers thought, the most isolated, and it was upon them, accordingly, that the attack was made. In the morning of April 11th, at a place called Rooiwal, the enemy, who had moved up from Wolmaranstad, nineteen hundred strong, under Kemp and Vermaas, fell with the utmost impetuosity upon the British column. There was no preliminary skirmishing, and a single gallant charge by 1500 Boers both opened and ended the engagement. 'I was just saying to the staff officer that there were no Boers within twenty miles,' says one who was present, 'when we heard a roar of musketry and saw a lot of men galloping down on us.' The British were surprised but not shaken by this unexpected apparition. 'I never saw a more splendid attack. They kept a distinct line,' says the eye-witness. Another spectator says, 'They came on in one long line four deep and knee to knee.' It was an old-fashioned cavalry charge, and the fact that it got as far as it did shows that we have over rated the stopping power of modern rifles. They came for a good five hundred yards under direct fire, and were only turned within a hundred of the British line. The Yeomanry, the Scottish Horse, and the Constabulary poured a steady fire upon the advancing wave of horsemen, and the guns opened with case at two hundred yards. The Boers were stopped, staggered, and turned. Their fire, or rather the covering fire of those who had not joined in the charge, had caused some fifty casualties, but their own losses were very much more severe. The fierce Potgieter fell just in front of the British guns. 'Thank goodness he is dead!' cried one of his wounded burghers, 'for he sjamboked me into the firing line this morning.' Fifty dead and a great number of wounded were left upon the field of battle. Rawlinson's column came up on Kekewich's left, and the Boer flight became a rout, for they were chased for twenty miles, and their two guns were captured. It was a brisk and decisive little engagement, and it closed the Western campaign, leaving the last trick, as well as the game, to the credit of the British. From this time until the end there was a gleaning of prisoners but little fighting in De la Rey's country, the most noteworthy event being a surprise visit to Schweizer-Renecke by Rochfort, by which some sixty prisoners were taken, and afterwards the drive of Ian Hamilton's forces against the Mafeking railway line by which no fewer than 364 prisoners were secured. In this difficult and well-managed operation the gaps between the British columns were concealed by the lighting of long veld-fires and the discharge of rifles by scattered scouts. The newly arrived Australian Commonwealth Regiments gave a brilliant start to the military history of their united country by the energy of their marching and the thoroughness of their entrenching.
Upon May 29th, only two days before the final declaration of peace, a raid was made by a few Boers upon the native cattle reserves near Fredericstad. A handful of horsemen pursued them, and were ambushed by a considerable body of the enemy in some hilly country ten miles from the British lines.
