This movement was carried out on the night of February 15th, and had it been a little quicker it might have been concluded before we were aware of it. But the lumbering wagons impeded it, and on the Friday morning, February 16th, a huge rolling cloud of dust on the northern veld, moving from west to east, told our outposts at Klip Drift that Cronje's army had almost slipped through our fingers. Lord Kitchener, who was in command at Klip Drift at the moment, instantly unleashed his mounted infantry in direct pursuit, while Knox's brigade sped along the northern bank of the river to cling on to the right haunch of the retreating column. Cronje's men had made a night march of thirty miles from Magersfontein, and the wagon bullocks were exhausted. It was impossible, without an absolute abandonment of his guns and stores, for him to get away from his pursuers. This was no deer which they were chasing, however, but rather a grim old Transvaal wolf, with his teeth flashing ever over his shoulder. The sight of those distant white-tilted wagons fired the blood of every mounted infantryman, and sent the Oxfords, the Buffs, the West Ridings, and the Gloucesters racing along the river bank in the glorious virile air of an African morning. But there were kopjes ahead, sown with fierce Dopper Boers, and those tempting wagons were only to be reached over their bodies. The broad plain across which the English were hurrying was suddenly swept with a storm of bullets. The long infantry line extended yet further and lapped round the flank of the Boer position, and once more the terrible duet of the Mauser and the Lee-Metford was sung while the 81st field battery hurried up in time to add its deep roar to their higher chorus. With fine judgment Cronje held on to the last moment of safety, and then with a swift movement to the rear seized a further line two miles off, and again snapped back at his eager pursuers. All day the grim and weary rearguard stalled off the fiery advance of the infantry, and at nightfall the wagons were still untaken. The pursuing force to the north of the river was, it must be remembered, numerically inferior to the pursued, so that in simply retarding the advance of the enemy and in giving other British troops time to come up, Knox's brigade was doing splendid work. Had Cronje been well advised or well informed, he would have left his guns and wagons in the hope that by a swift dash over the Modder he might still bring his army away in safety. He seems to have underrated both the British numbers and the British activity.
