Following the Battle of Paardeberg (18–27 February), the relief of Kimberley and Ladysmith and the fall of Bloemfontein, General Frederick Roberts reorganised his force to pursue the defeated Boers. At the same time Lieutenant general Paul Methuen was tasked with clearing the country along the Vaal River on the Boers' flank and to drive towards Mafeking, which was still besieged.
