No one but a Boer leader with a supreme contempt for his enemy would have thought of placing himself within striking distance of Pretoria and Johannesburg. Yet on January 11, 1901, he audaciously laagered within a few miles of Johannesburg, unknown to the garrison. Next day he crossed the railway at Kaalfontein, half-way between the two cities, and disappeared in the Eastern Transvaal. That at this stage of the war it was possible for 1,200 men to cut the railway, and with scarcely the loss of a man to cross it, with guns and a long train of wagons, midway between the two chief cities of the Transvaal, showed how much still remained to be done. The disturbances in the Orange River Colony brought about certain changes and redistributions in the Transvaal commands, by which leaders were, as in the circuits of Wesleyan ministers, removed from spheres familiar to them. Clements went to Pretoria in succession to Tucker, who was sent to Bloemfontein; E. Knox, who, fifteen months previously, had been in command of the squadrons of the 18th Hussars which were not made prisoners of war at Talana, took command of the column of Broadwood, who was sent across the Vaal; Cunningham succeeded Clements in the Magaliesberg district; Hart quitted Klerksdorp for the Orange River Colony; and French went away into the west. On the Boer side a new name which was destined often to be on men's lips emerged from the crowd in January, 1901. A young lawyer named J.C. Smuts, who had received his legal education in England, and whom Delarey entrusted with a command, soon showed, and not for the first time, that a shrewd, resourceful, energetic and determined civilian was, at least in _guerilla_, more than a match for highly trained British officers. A movement towards the south by Cunningham, with a view of checking Delarey, soon brought Cunningham into trouble. After crossing the Magaliesberg he was entangled by the Transvaal leader, and had to be extricated by Babington before he could proceed to his destination at Krugersdorp. [Sidenote: Map, p. 292.] Smuts, the new leader, went to the Gatsrand. His first exploit was to snap up a weak and isolated British detachment at Modderfontein Nek, and to establish his own commando on the position. When Cunningham reached Krugersdorp he received orders to tackle Smuts. On February 2, having an overwhelming superiority in guns and a considerable advantage in numbers, he attacked Smuts; but the apprentice tactician had little difficulty in meeting the regulation frontal holding attack combined with a turning movement, and Cunningham withdrew.
