Kekewich reached Roodeval early on April 11, and at once pressed forward to Hart's River. His advanced guard almost immediately discovered a large body of mounted men on the left front, who, until they opened fire, were by some strange misconception taken to be a portion of Rawlinson's column. They were in fact more than a thousand Boers under Potgieter, who as soon as he had disposed of the advanced guard, made for the main body, which was not yet formed up, and by which Potgieter's men were again mistaken for a portion of Rawlinson's column. The error was discovered, but not too late. The Boer attack, which for sheer reckless bravery could hardly be surpassed, and which has been compared to the Dervish charge at Omdurman, was made in the open against a considerable force, was repelled; and Potgieter fell dead at the head of his commandos. Rawlinson hurried up to the sound of the firing and drove away the enemy, who retired, but not in disorder, to the south. A remnant, however, broke back and even sniped the main body. In less than three hours after the first shot had been fired by Potgieter, Kekewich and Rawlinson started in pursuit. Kemp, however, saved himself, and escaped with what was, under the circumstances, the inconsiderable loss of the two field guns which Delarey had taken from Methuen at Tweebosch. The two Hamiltons rang down the curtain of the War Tragedy. While Bruce Hamilton was driving for the last time through the Orange River Colony, Ian Hamilton with Kekewich, W. Kitchener, and Rawlinson, assisted by a column from the Vaal under Rochfort, began a westward drive in the Transvaal, with 17,000 men. Kemp followed the usual practice of Boer commandants when hard pressed by the enemy, and scattered his commandos; thus when Ian Hamilton's 17,000 crossed the border and reached the Western Railway on May 11, they found less than 400 Boers, among whom Kemp was not, impaled upon the barrier of blockhouses and armoured trains. IV. CAPE COLONY During the early part of the summer of 1901-2 the Cape Colony was, comparatively speaking, quiet, though dormantly rebellious. Little positive progress was made, either by French or by the inflammatory elements opposed to him, of which the leader was J.C. Smuts. These were for the most part acting in a spacious and inaccessible area, which included the districts of Kenhart, Carnarvon, Sutherland, Fraserburg, and Calvinia. A blockhouse line, which when completed would stretch from Victoria West to Lambert's Bay, was in course of construction through these districts.
