He remained for some weeks seeing to the drifts, which were now in his possession and now in that of the enemy. A Boer raid into Rhodesia on November 2 forced the outlying detachments back upon Tuli, which was seriously threatened by some commandos under F.A. Grobler of Marico. The Government of Pretoria, however, growing anxious at the presence of British troops elsewhere, vetoed a promising enterprise and recalled him. The raid of November 2 was answered a few weeks later by Plumer, who, finding the drifts unoccupied, reconnoitred thirty miles towards the south. Nearly six months elapsed before another British soldier set foot in the Transvaal. A subsequent reconnaissance again found no trace of the enemy on the left bank of the Limpopo, and showed that it was unnecessary for him to remain on the river. He had the advantage of being cut off from communication with superior officers ignorant of local conditions, and was able to act freely upon his own responsibility. He soon heard news which clearly indicated the way he should go. The railway from Buluwayo to Mafeking was held as far as possible towards the south by patrols of police under Nicholson, and the Rhodesian Volunteers under Holdsworth were also on the line. In the gap between the railhead and Mafeking, a Boer commando, said to have been detached from Mafeking by Cronje, was at Sekwani on the N.W. border of the Transvaal and within striking distance of the Western line. It was face to face with the border tribes and was soon in trouble with them. Although they were not allowed to attack Sekwani independently, they were permitted to co-operate as non-combatants in an attack which Holdsworth was about to make on it, but only on the condition that they did not cross the Transvaal border. This was a refinement of policy which they could hardly be expected to understand, and they precipitated Holdsworth's action by attacking the Boer laager, which lay but a mile or two across the border, on their own account, and the operation had therefore to be abandoned. To avenge this native attack, in which several burghers had been killed, reinforcements were brought over by the Boers from the Pietersburg line, and Holdsworth's position at Mochudi on the Western line, whither he had retired after the Sekwani failure, was endangered.
