Hart's sphere of action was originally round Potchefstroom. On September 9th he made a fine forced march to surprise this town, which had been left some time before with an entirely inadequate garrison to fall into the hands of the enemy. His infantry covered thirty-six and his cavalry fifty-four miles in fifteen hours. The operation was a complete success, the town with eighty Boers falling into his hands with little opposition. On September 30th Hart returned to Krugersdorp, where, save for one skirmish upon the Gatsrand on November 22nd, he appears to have had no actual fighting to do during the remainder of the year.

After the clearing of the eastern border of the Transvaal by the movement of Pole-Carew along the railway line, and of Buller aided by Ian Hamilton in the mountainous country to the north of it, there were no operations of importance in this district. A guard was kept upon the frontier to prevent the return of refugees and the smuggling of ammunition, while General Kitchener, the brother of the Sirdar, broke up a few small Boer laagers in the neighbourhood of Lydenburg. Smith-Dorrien guarded the line at Belfast, and on two occasions, November 1st and November 6th, he made aggressive movements against the enemy. The first, which was a surprise executed in concert with Colonel Spens of the Shropshires, was frustrated by a severe blizzard, which prevented the troops from pushing home their success. The second was a two days' expedition, which met with a spirited opposition, and demands a fuller notice.
