If Lord Roberts needed justification for this decision, the future course of events will furnish it. One of Napoleon's maxims in war was to concentrate all one's energies upon one thing at one time. Roberts's aim was to outflank and possibly to capture Cronje's army. If he allowed a brigade to be involved in a rearguard action, his whole swift-moving plan of campaign might be dislocated. It was very annoying to lose a hundred and eighty wagons, but it only meant a temporary inconvenience. The plan of campaign was the essential thing. Therefore he sacrificed his convoy and hurried his troops upon their original mission. It was with heavy hearts and bitter words that those who had fought so long abandoned their charge, but now at least there are probably few of them who do not agree in the wisdom of the sacrifice. Our loss in this affair was between fifty and sixty killed and wounded. The Boers were unable to get rid of the stores, and they were eventually distributed among the local farmers and recovered again as the British forces flowed over the country. Another small disaster occurred to us on the preceding day in the loss of fifty men of E company of Kitchener's Horse, which had been left as a guard to a well in the desert. But great events were coming to obscure those small checks which are incidental to a war carried out over immense distances against a mobile and enterprising enemy. Cronje had suddenly become aware of the net which was closing round him. To the dark fierce man who had striven so hard to make his line of kopjes impregnable it must have been a bitter thing to abandon his trenches and his rifle pits. But he was crafty as well as tenacious, and he had the Boer horror of being cut off--an hereditary instinct from fathers who had fought on horseback against enemies on foot. If at any time during the last ten weeks Methuen had contained him in front with a thin line of riflemen with machine guns, and had thrown the rest of his force on Jacobsdal and the east, he would probably have attained the same result. Now at the rumour of English upon his flank Cronje instantly abandoned his position and his plans, in order to restore those communications with Bloemfontein upon which he depended for his supplies. With furious speed he drew in his right wing, and then, one huge mass of horsemen, guns, and wagons, he swept through the gap between the rear of the British cavalry bound for Kimberley and the head of the British infantry at Klip Drift. There was just room to pass, and at it he dashed with the furious energy of a wild beast rushing from a trap. A portion of his force with his heavy guns had gone north round Kimberley to Warrenton; many of the Freestaters also had slipped away and returned to their farms. The remainder, numbering about six thousand men, the majority of whom were Transvaalers, swept through between the British forces.
