Sir G. White moved out from Ladysmith at 5 a.m. with the 5th Lancers, 19th Hussars, Imperial Light Horse, Natal Mounted Rifles, 42nd and 53rd batteries R.F.A., No. 10 Mountain battery R.G.A., 1st Liverpool, 1st Devon, 1st Gloucestershire regiments, and 2nd King's Royal Rifle Corps, in all, some 5,300 officers and men, assuming himself the direction of an operation certain to be delicate, likely to be extremely dangerous. Moving up the Newcastle road from its rendezvous near the junction of the Free State railway, the force had proceeded six miles when the advanced screen of cavalry came under a dropping rifle fire at 7 a.m. from the heights on their left. Their action was prompt. Pushing rapidly across the Modder Spruit, a squadron of 5th Lancers, supported by two others, drove back at the gallop the small parties of Boers hovering in that neighbourhood, and themselves seized and held this advanced position. The remainder of the cavalry, stringing out along high ground dominating the western bank of the spruit, and facing more to the eastward, formed a strong flank guard towards Jonono's Kop. At 8 a.m., whilst fitful discharges of musketry rose and fell along the widely-extended line of troopers, the infantry had come up to Rietfontein. No sooner had they arrived at a point on the road some five hundred yards east of the Modder Spruit, than a loud report broke from the eastern peak of Intintanyoni, and a shell, bursting on impact, fell into the head of the column. Thereupon the British artillery wheeled out from the route, and in line of batteries trotted towards a level crossing over the railway, some six hundred yards west of the road. Arrived at this defile, and forming column inwards to traverse it, the first gun had scarcely passed the rails, when both the Boer guns on the high green rampart ahead opened upon the point, which had been taken as one of their range marks. Five hundred yards beyond it the artillery deployed behind a rise. The second round from the 53rd battery, fused at 3,600 yards, burst full upon one of the Boer pieces, and the gunners of both weapons fled. After a few more rounds the 53rd limbered up and prepared to advance. [Sidenote: The infantry seize ridge facing hill.]
