In order to strike unexpectedly, Lord Roberts had not only made a strong demonstration at Koodoosdrift, at the other end of the Boer line, but he had withdrawn his main force some forty miles south, taking them down by rail to Belmont and Enslin with such secrecy that even commanding officers had no idea whither the troops were going. The cavalry which had come from French's command at Colesberg had already reached the rendezvous, travelling by road to Naauwpoort, and thence by train. This force consisted of the Carabineers, New South Wales Lancers, Inniskillings, composite regiment of Household Cavalry, 10th Hussars, with some mounted infantry and two batteries of Horse Artillery, making a force of nearly three thousand sabres. To this were added the 9th and 12th Lancers from Modder River, the 16th Lancers from India, the Scots Greys, which had been patrolling Orange River from the beginning of the war, Rimington's Scouts, and two brigades of mounted infantry under Colonels Ridley and Hannay. The force under this latter officer had a severe skirmish on its way to the rendezvous and lost fifty or sixty in killed, wounded, and missing. Five other batteries of Horse Artillery were added to the force, making seven in all, with a pontoon section of Royal Engineers. The total number of men was about five thousand. By the night of Sunday, February 11th, this formidable force had concentrated at Ramdam, twenty miles north-east of Belmont, and was ready to advance. At two in the morning of Monday, February 12th, the start was made, and the long sinuous line of night-riders moved off over the shadowy veld, the beat of twenty thousand hoofs, the clank of steel, and the rumble of gunwheels and tumbrils swelling into a deep low roar like the surge upon the shingle. Two rivers, the Riet and the Modder, intervened between French and Kimberley. By daylight on the 12th the head of his force had reached Waterval Drift, which was found to be defended by a body of Boers with a gun. Leaving a small detachment to hold them, French passed his men over Dekiel's Drift, higher up the stream, and swept the enemy out of his position. This considerable force of Boers had come from Jacobsdal, and were just too late to get into position to resist the crossing. Had we been ten minutes later, the matter would have been much more serious. At the cost of a very small loss he held both sides of the ford, but it was not until midnight that the whole long column was brought across, and bivouacked upon the northern bank. In the morning the strength of the force was enormously increased by the arrival of one more horseman. It was Roberts himself, who had ridden over to give the men a send-off, and the sight of his wiry erect figure and mahogany face sent them full of fire and confidence upon their way.
