The situation was alarming. The districts west and south-west of the capital were infested by energetic commandos which had thwarted all Baden-Powell's and Smith-Dorrien's efforts to suppress them, and Grobler was threatening Pretoria from the north. There were indications that the enemy's plan was to transfer the opposition from the east to the west; and if so, then Lord Roberts' force, whose front after Diamond Hill faced eastwards, would have to conform to the movement. A few weeks previously it had been weakened by the departure of Hunter's strong column for the Free State, and now Lord Roberts was compelled to redress the balance by calling up Methuen's Division from Lindley to Krugersdorp, where it arrived on July 18. French was ordered to operate north of Pretoria with cavalry, and a column under Ian Hamilton[49] was also sent up. Methuen marched at once on Rustenburg, and cleared Olifant's Nek on July 21. The scheme of shutting up the Boers in it failed, as Baden-Powell was unable to close the northern exit, and they escaped with slight loss. At the beginning of August the situation was, if anything, worse. The events which succeeded the occupation of Bloemfontein were repeating themselves in the Western Transvaal. Methuen had been recalled from the Rustenburg expedition to deal with an outbreak on the line from Johannesburg to Klerksdorp, which fell into the hands of the enemy; 5,000 Boers were reported to be on or near the Magaliesberg; a small British force was besieged in Brakfontein, west of Rustenburg, on the road to Mafeking; De Wet was at large in the Free State, and it seemed probable that he would come up into the Transvaal and add to the trouble.
