On Feb. 25th Col. von Donop's empty convoy of 160 mule wagons (2,000 mules) was attacked and captured at daybreak 8 miles from Klerksdorp by General Delarey and 1,500 Boers. The convoy was trekking from Wolmeranstadt to Klerksdorp for supplies, under an escort of 360 men, composed of Yeomanry and two or three companies Northumberland Fusiliers, with two field guns and a pom-pom and a maxim---all of which were taken by the Boers. Major Anderson, commanding the escort, sent in to Klerksdorp for reinforcements, and Major Hearn, with Lieut. Beeton, and about thirty men of the 21st M. I. (who had been sent in to Klerksdorp for remounts) moved out of the town towards Wolmeranstadt about 7.30 a.m., and were subsequently joined by two troops of Scottish Horse, some men of No. 2 Co. 21st M. I., with Lieut. Drinan, and other details, making up a total of perhaps 250 men. This force, commanded by Col. Grenfell, 1st Life Guards, galloped 6 miles towards the scene of the disaster, subsequently reaching high ground from which the captured convoy could be seen, turned about and moving off in an opposite direction. The woods on the right of the road were occupied by large numbers of Boers, who could be clearly seen, as well as a great number trekking away over the hills. Col. Grenfell's men dismounted and opened fire at 1,000 yards. Part of the force charged down the hill in an attempt to recapture half-a-dozen wagons, which had been blocked and overturned in the Spruit; whereupon the Boers in large numbers formed up and galloped, firing from their saddles, down the hill opposite, towards the British, compelling them to retire, with a loss of several horses killed and two men of the Scottish Horse wounded. The Boers did not continue the pursuit, being satisfied with the capture of the entire convoy, and the guns, with the exception of the maxim, which was galloped into Klerksdorp on a pack horse. The casualties among the convoy escort were over 200. Two officers of the Northumberland Fusiliers were killed, and three severely wounded. On March 14th Lord Kitchener concentrated a large force in the vicinity of Klerksdorp with the object of destroying Delarey's commandos. Col. Grenfell, 1st Life Guards, took command of all mounted troops belonging to the three columns (Col. von Donop's, Col. Kekewich's, and Col. Grenfell's), together 1,500 strong. The first of the combined drives began on March 16th and occupied five days, the enemy being driven from S.-W. to N.-E., in the direction of Klerksdorp. Owing to a gap left by General W. Kitchener's column, most of the Boers escaped over the hills, near Brakspruit, 9 miles from Klerksdorp. The 21st M. I. came in touch with a party of Boers quite unexpectedly at nightfall, and after galloping a few miles in pursuit drove them in the direction of General Kitchener's column, where sixteen subsequently were taken prisoners.
