Buller's column had come nearer to its friends, but it was also nearer to the main body of Boers who were waiting in that very rugged piece of country which lies between Belfast in the west and Machadodorp in the east. From this rocky stronghold they had thrown out mobile bodies to harass the British advance from the south, and every day brought Buller into closer touch with these advance guards of the enemy. On August 21st he had moved eight miles nearer to Belfast, French operating upon his left flank. Here he found the Boers in considerable numbers, but he pushed them northward with his cavalry, mounted infantry, and artillery, losing between thirty and forty killed and wounded, the greater part from the ranks of the 18th Hussars and the Gordon Highlanders. This march brought him within fifteen miles of Belfast, which lay due north of him. At the same time Pole-Carew with the central column of Lord Roberts's force had advanced along the railway line, and on August 24th he occupied Belfast with little resistance. He found, however, that the enemy were holding the formidable ridges which lie between that place and Dalmanutha, and that they showed every sign of giving battle, presenting a firm front to Buller on the south as well as to Roberts's army on the west.
