Orange Free State

From then until the final days of the war, De Wet remained comparatively quiet, rarely attacking British army camps and columns partly because the Orange Free State was effectively left desolate by British sweeps. In late 1901, De Wet overran an isolated British detachment at Groenkop, inflicting heavy casualties. This prompted Kitchener to launch the first of the "New Model" drives against him. De Wet escaped the first such drive but lost 300 of his fighters. This was a severe loss, and a portent of further attrition, although the subsequent attempts to round up De Wet were badly handled, and De Wet's forces avoided capture.
