Some attempt has now been made to sketch the succession of events which had ended in the investment of Ladysmith in northern Natal, and also to show the fortunes of the force which on the western side of the seat of war attempted to advance to the relief of Kimberley. The distance between these forces may be expressed in terms familiar to the European reader by saying that it was that which separates Paris from Frankfort, or to the American by suggesting that Ladysmith was at Boston and that Methuen was trying to relieve Philadelphia. Waterless deserts and rugged mountain ranges divided the two scenes of action. In the case of the British there could be no connection between the two movements, but the Boers by a land journey of something over a hundred miles had a double choice of a route by which Cronje and Joubert might join hands, either by the Bloemfontein-Johannesburg-Laing's Nek Railway, or by the direct line from Harrismith to Ladysmith. The possession of these internal lines should have been of enormous benefit to the Boers, enabling them to throw the weight of their forces unexpectedly from the one flank to the other. In a future chapter it will be recorded how the Army Corps arriving from England was largely diverted into Natal in order in the first instance to prevent the colony from being overrun, and in the second to rescue the beleaguered garrison. In the meantime it is necessary to deal with the military operations in the broad space between the eastern and western armies.
