On Thursday, January 11, Sir Redvers Buller began his operations for forcing the Tugela and relieving Ladysmith. Barton's Brigade entrenched itself at Chieveley, guarding the line of railway communication. Hildyard's Brigade marched westward six miles to Pretorius's Farm, where they were joined by the cavalry, the naval guns, three batteries Field Artillery, and Hart's Brigade from Frere. The infantry and two batteries remained and encamped, making Clery's division, while the mounted forces under Dundonald moved forward to take the bridge across the Little Tugela at Springfield, and, finding this unoccupied, pushed on and seized the heights overlooking Potgieter's Drift on the Tugela, On the 12th Warren's division, comprising the brigades of Lyttelton and Woodgate, with three batteries, marched to Springfield, where they camped. On the 13th the mounted troops, holding the heights above Potgieter's Drift, were strengthened by the arrival of two battalions of Lyttelton's Brigade from Springfield. Sir Redvers Buller established his headquarters in this camp. On the 14th the rest of the brigade followed, and the same day the corps troops, consisting of Coke's Brigade, one howitzer, and one field battery, reached Springfield. On the 15th Coke moved to the position before Potgieter's, and the naval guns were established on the heights commanding the ford. All this while the Boers contented themselves with fortifying their horseshoe position which enclosed the debouches from Potgieter's Drift, and only picket firing disturbed the general peace.
