At this date with Lord Roberts in Pretoria were two and a half infantry divisions, a cavalry division, and a mounted infantry division, Wavell's Brigade having been left at Johannesburg, while the other half proceeded to the Capital. General Hunter's Division, joined by Colonel Mahon's force, was operating at Ventersdorp, while Colonel Plumer without opposition occupied Zeerust, the officials agreeing to take the oath provided they were protected from their fellow-countrymen. Elsewhere, across the Orange River Colony, the troops were fairly well expanded. General Colvile with the Highland Brigade was near Heilbron, and south of him Lord Methuen, while at Lindley was General Paget. At Senekal and Hammonia were General Clements and General Rundle respectively. South of these again, Generals Chermside and Brabant were operating. It was imagined that the combined vigilance of these officers had entirely protected the communications in the Orange River Colony, but on the 7th of June the unquenchable Dutchmen succeeded in cutting line and telegraph wire north of Kroonstad, and in taking prisoners most of the 4th Battalion of the Derbyshires (Sherwood Foresters), who were guarding the district. Of the battalion, the Colonel, a lieutenant, and thirty-four rank and file were killed, five officers and ninety-nine men were wounded, and the rest, save six, made prisoners! The story ran thus: At dusk on the 4th, the Derbyshire Militia Regiment arrived at Roodeval and pitched their camp in the lee of a string of kopjes that shelved away to the west, and terminated in a high hump which, jutting out of the plain, commanded rail, camp, and the surrounding hills. Owing to the darkness it was impossible to do much in the way of reconnoitring, and though some scouts and natives warned the commanding officers that Boers had been espied in the vicinity, little notice was taken. The pickets, which had been posted on a range of kopjes north of the camp, were strengthened, and some few shots fired at distant snipers. Then the party laid themselves down to rest, and slept placidly. Before dawn they were awakened by the furious crackling of musketry, and even as the men turned out with their rifles, they dropped. One after another as they left their tents fell victims to the unseen foe. The fact was, the pickets had been attacked and driven in, and the enemy occupied the range which commanded the British troops. Presently the early morning was humming with shot and shell, the Boers now having brought four big guns and a pom-pom to bear on the unfortunate camp and the bald plain that surrounded it. Valiantly the militiamen, raw and unfledged warriors as they were, fought; long, bloody, and disastrous hours passed, and they, falling thick as autumn leaves, continued to hold out in a completely defenceless position till the plain was littered with dead and wounded--more than eighty of them now lying in a trap from which it was impossible to escape.
