On Sunday afternoon the Infantry Brigades began to move to their respective positions, and at daylight on the 5th the Cavalry Division broke its camp behind spearman's. At nine minutes past seven he bombardment of the Brakfontein position began, and by half-past seven all the Artillery except the Swartkop guns were firing in a leisurely fashion at the Boer redoubts and entrenchments. At the same time Wynne's Brigade moved forward in dispersed formation towards the enemy, and the Cavalry began to defile across the front and to mass near the three Infantry Brigades collected near No. 2 pontoon bridge. For some time the Boers made no reply, but at about ten o'clock their Vickers-Maxim opened on the batteries firing from the Potgieter's plain, and the fire gradually increased as other guns, some of great range, joined in, until the Artillery was sharply engaged in an unsatisfactory duel--fifty guns exposed in the open against six or seven guns concealed and impossible to find. The Boer shells struck all along the advanced batteries, bursting between the guns, throwing up huge fountains of dust and smoke, and covering the gunners at times completely from view. Shrapnel shells were also flung from both flanks and ripped the dusty plain with their scattering bullets. But the Artillery stood to their work like men, and though they apparently produced no impression on the Boer guns, did not suffer as severely as might have been expected, losing no more than fifteen officers and men altogether. At intervals of ten minutes the batteries withdrew in beautiful order and ceremony and defiled across the second pontoon bridge. Meanwhile Wynne's Brigade had advanced to within twelve hundred yards of the Brakfontein position and retired, drawing the enemy's heavy fire; the three brigades under Clery had moved to the right near Munger's Drift; the Cavalry were massed in the hollows at the foot of Swartkop; and the Engineers had constructed the third pontoon bridge, performing their business with excellent method and despatch under a sharp fire from Boer skirmishers and a Maxim.
