Capture of Pretoria

British observers believed the war to be all but over after the capture of the two capital cities. However, the Boers had earlier met at the temporary new capital of the Orange Free State, Kroonstad, and planned a guerrilla campaign to hit the British supply and communication lines. The first engagement of this new form of warfare was at Sanna's Post on 31 March where 1,500 Boers under the command of Christiaan de Wet attacked Bloemfontein's waterworks about 37 kilometres (23 mi) east of the city, and ambushed a heavily escorted convoy, which caused 155 British casualties and the capture of seven guns, 117 wagons, and 428 British troops.
