From De Aar a division will support the left flank of the advance of the First Army Corps, divided, for purposes of more speedy concentration upon its ultimate base, into two divisions, which will reunite at Burghersdorp, _viâ_ the railways, to Middelburg and Stormberg Junction from their immediate bases of disembarkation at Port Elizabeth and East London. The total force will then advance in exterior lines upon the Orange Free State, maintaining the railway system upon their individual western flanks, so far as possible, as their individual lines of communication. While the Second Army Corps supports the situation in Natal, it is hoped that our forces in the Orange Free State border will either crush or drive the Boers back upon their ulterior lines towards Bloemfontein, which, with the assistance of the De Aar flanking column traversing the watershed of the Modder River in the direction of Kimberley, and in possible co-operation with a force from that base, they should be in a position to occupy. The capital will be held by the De Aar and Kimberley divisions, upon whom will then fall the work of protecting the lines of communication of the Southern Army Corps as it advances. After supporting De Aar, Kimberley, and the lines of communication with defensive units, and maintaining a western column by employing the service of the Mafeking force, the First Army Corps will begin the move upon Pretoria, in collaboration with the Second (Natal) Army Corps, the former once again advancing in twin columns from a mutual base. The western border will probably be held from Kimberley to Fort Tuli by the forces composing the western column, while a flying column is to be in readiness lest a wider area be given to the theatre of war, and it become necessary to cross the Limpopo River. It would appear, too, that there is also some possibility of a column moving from Delagoa Bay. By this advance Pretoria becomes the objective of the campaign after the occupation of the Orange Free State, but this depends to a great extent upon the policy pursued by General Joubert and the nature of the Natal operations. If the Boers give way and, acting upon interior lines, fall back upon Pretoria, as General Jackson fell back upon Richmond in 1864-1865, the Transvaal capital will at once become the objective of the British forces advancing upon exterior lines, the object of the campaign, once the Transvaal has been invaded, being to force a battle upon the combined forces of the Boers or to beset Pretoria. It will thus be seen that the theory of the British advance favours the concentration of troops upon the Transvaal and Orange Free State frontiers so that the Boer forces may be dislocated, retaining the railways and their lines of communication and, leaving the actual protection and pacification of the frontier to the local mounted police and to the special service corps assisted by a few detachments of Imperial troops, while no progressive movement
