General Beatson meanwhile, on the night of the 7th of July, had done some highly effective work. His surprise visit to the laager of Commandant Trichard, which was located some twenty-five miles north of Middelburg, resulted in the breaking up of the marauding gang and the dispersal of them into the rugged country round Olifant River. The commandant himself merely escaped by "the skin of his teeth." Further pursuit being useless, the General returned to Middelburg and assisted in the hunt for Viljoen, who was not to be caught, however, for he had warily doubled back to his friendly kopjes on the right bank of the Olifant. Returning to Bronkerspruit Station along the Wilge River General Beatson, while searching in all the adjacent kloofs, came on twenty-five waggons containing ammunition and clothing. As the duties of most clearing columns were very much alike, some quotations from an officer's letter may serve to show the nature of the work and of the country to be cleared of Boers and supplies:-- "The usual proceeding is as follows: On the first day we occupy the high ridges on each side of one of the huge valleys, or kloofs, as they are called. This the Boers, with the exception of a few 'snipers,' who wound or kill one or two of our advanced scouts, do not attempt to oppose. Then begins the difficulty. From each side the ground slopes down very steeply--in many places it means recourse to hands and knees--for about a mile; then comes a sheer precipice about 100 feet deep, and at the bottom a valley about 100 to 500 yards broad, with a stream in the middle and very thickly wooded. On each side of the main valley the cliffs are broken by smaller kloofs running up them, and they contain any number of caves and huge boulders. On the whole, one of these valleys makes about as difficult a bit of country to clear as any you could imagine. The Boers lie hidden among the rocks and in caves, and 'snipe' from them heavily at any man attempting to climb down the precipitous sides. We generally spend a day or two in shelling and advancing as far as the edges of the precipices, and then on the night before we send our infantry down into the valley most of the Boers escape. They dispute every inch of the way until they see that the position is untenable for them. Then off they go." The writer of the letter mentioned a particular instance of this kind of work, in which the Boer women hung white flags all over their laager, and some Boers took advantage of the fact that the British gunners duly respected the flags to hide among the rocks round the laager, and to "snipe" the troops as they advanced.
