General Bullock, who on the 25th of May was joined by Colonel Grey (from Standerton), now commenced a series of night raids on various farmhouses along the banks of the Vaal, south-east of Ermelo--excursions which were full of dash and daring, and resulted in the capture of many armed burghers. June found both columns at Standerton. Five days later Colonel Grey started on an adventurous hunt for a Boer gun, said to be with a commando at Kaffir Spruit. On the 11th the force surprised a Boer laager at Rietvlei, and after a vigorous fight nine prisoners were secured. One Boer was killed and two wounded. Colonel Grey, having thoroughly searched the district between Ermelo and Bethel without finding a trace of the required gun, returned to Standerton. From the 10th of June to the 4th of July, General Bullock continued his clearance of the country, dispersing Boer gangs east of Elandsberg down to the valley of the Assegai River. He was then called in to the railway and returned to Standerton. BRIGADIER-GENERAL PLUMER IN THE EASTERN TRANSVAAL General Plumer, as soon as he had refitted his troops at Standerton, was again off to engage in further sweeping operations against Boer knots in the region between Amersfoort and Piet Retief. General Plumer, with Colonel Rimington on his right flank and Colonel Knox on his left, advanced on the 1st of June on the line Platrand-Springbokfontein-Uitkyk. By the 8th, all three columns had reached the line Driefontein-Breda-Waterval Drift, and thus, on the following day, the columns of Plumer (centre) and Knox (left) were able to swoop from the north upon Piet Retief, while that of Rimington (right), making a night détour, wheeled round the south of the town and blocked all southerly exits therefrom. But, warily, the Boers had made off, and the place was deserted. Colonel Rimington, however, contrived to cut off a Boer convoy which was hastily lumbering along towards the Vryheid Road, accompanied by the escaping Landdrost of Piet Retief and William Emmett, who were forthwith taken prisoners together with twenty-eight more of their compatriots. Twelve waggons and 100 horses were also secured. Colonel Rimington then stationed himself south-east of the difficult peaks of the Slangapiesberg, while they were traversed by Colonel Plumer's troops, who, having moved from Piet Retief towards Wakkerstroom to meet a convoy, were now proceeding over the dangerous heights. The whole force having cleared "as far as practicable" this gibbose and frowning region, moved to Paul Pietersburg, which was also found deserted. Near Elandsberg Nek, however, Colonel Gallway, with some 300 Bushmen, two companies of Munster Fusiliers, and some Sharpshooters, with two guns of Q Battery, were assailed by 300 Boers, who were strongly entrenched there. The enemy were speedily dispersed, but Lieutenant Rudkin, R.H.A., was wounded in both knees, and narrowly escaped death, as a Boer bullet passed through the litter
