Some explanation is needed of Lord Methuen's appearance upon the central scene of warfare, his division having, when last described, been at Boshof, not far from Kimberley, where early in April he fought the successful action which led to the death of Villebois. Thence he proceeded along the Vaal and then south to Kroonstad, arriving there on May 28th. He had with him the 9th Brigade (Douglas's), which contained the troops which had started with him for the relief of Kimberley six months before. These were the Northumberland Fusiliers, Loyal North Lancashires, Northamptons, and Yorkshire Light Infantry. With him also were the Munsters, Lord Chesham's Yeomanry (five companies), with the 4th and 37th batteries, two howitzers and two pom-poms. His total force was about 6000 men. On arriving at Kroonstad he was given the task of relieving Heilbron, where Colvile, with the Highland Brigade, some Colonial horse, Lovat's Scouts, two naval guns, and the 5th battery, were short of food and ammunition. The more urgent message from the Yeomen at Lindley, however, took him on a fruitless journey to that town on June 1st. So vigorous was the pursuit of the Yeomanry that the leading squadrons, consisting of South Notts Hussars and Sherwood Rangers, actually cut into the Boer convoy and might have rescued the prisoners had they been supported. As it was they were recalled, and had to fight their way back to Lindley with some loss, including Colonel Rolleston, the commander, who was badly wounded. A garrison was left under Paget, and the rest of the force pursued its original mission to Heilbron, arriving there on June 7th, when the Highlanders had been reduced to quarter rations. 'The Salvation Army' was the nickname by which they expressed their gratitude to the relieving force.
A previous convoy sent to the same destination had less good fortune. On June 1st fifty-five wagons started from the railway line to reach Heilbron. The escort consisted of one hundred and sixty details belonging to Highland regiments without any guns, Captain Corballis in command. But the gentleman with the tinted glasses was waiting on the way. 'I have twelve hundred men and five guns. Surrender at once!' Such was the message which reached the escort, and in their defenceless condition there was nothing for it but to comply. Thus one disaster leads to another, for, had the Yeomanry held out at Lindley, De Wet would not on June 4th have laid hands upon our wagons; and had he not recruited his supplies from our wagons it is doubtful if he could have made his attack upon Roodeval. This was the next point upon which he turned his attention.
Two miles beyond Roodeval station there is a well-marked kopje by the railway line, with other hills some distance to the right and the left. A militia regiment, the 4th Derbyshire, had been sent up to occupy this post. There were rumours of Boers on the line, and Major Haig, who with one thousand details of various regiments commanded at railhead, had been attacked on June 6th but had beaten off his assailants. De Wet, acting sometimes in company with, and sometimes independently of, his lieutenant Nel, passed down the line looking fur some easier prey, and on the night of June 7th came upon the militia regiment, which was encamped in a position which could be completely commanded by artillery. It is not true that they had neglected to occupy the kopje under which they lay, for two companies had been posted upon it. But there seems to have been no thought of imminent danger, and the regiment had pitched its tents and gone very comfortably to sleep without a thought of the gentleman in the tinted glasses. In the middle of the night he was upon them with a hissing sleet of bullets. At the first dawn the guns opened and the shells began to burst among them. It was a horrible ordeal for raw troops. The men were miners and agricultural labourers, who had never seen more bloodshed than a cut finger in their lives. They had been four months in the country, but their life had been a picnic, as the luxury of their baggage shows.
