Another point influenced by the unwillingness of Her Majesty's Government to believe in the possibility of the Orange Free State, with which we had had for many years relations of the greatest friendliness, appearing in arms against us, was this: that it delayed for a very considerable time the determination of the general plan of campaign on which the war was to be carried on. Practically, supposing it became necessary to conduct an offensive war against the Transvaal, the choice of operations lay between a movement by way of Natal and one by way of the Orange Free State. Any advance by Natal had these serious disadvantages. In the first place, the mountain region through which it would be necessary to penetrate was one that gave very great advantages to the Boer riflemen. In the second place, it lay exposed, as soon as Northern Natal was entered, to attack throughout its entire length from the Orange Free State. On the other hand, the march by Bloemfontein opened up a country much more favourable for the operations of a regular army, whether that march, as was originally proposed, followed the direct line of railway through Bloemfontein, or, as it did ultimately, the railway to Kimberley and thence struck for Bloemfontein.[1] There remained, indeed, a third alternative, which had at one time been proposed by Lord Roberts, of a movement outside the Orange Free State through the north-western portion of Cape Colony, but this had ceased to be applicable at the time when war was declared. As a consequence of the uncertainties as to the ultimate attitude of the Orange Free State, and the extreme hope that that State would not prove hostile, it was not till the 3rd October that Lord Lansdowne was in a position to say: "We have now definitely decided to adopt the Cape Colony--Orange Free State route. It is intended that a force of 10,000 men should remain in Natal, on which side it will make a valuable diversion; that about 3,000 should be detailed for service on the west side (Kimberley, etc.), and that the main force should enter the Orange Free State from the south."
