The scheme provided that Col. Rochfort should come up at night from the south, and get touch with the large bodies of troops that would be sent westward from Klerksdorp, and that the whole should turn eastwards in the morning, forming a gigantic net which would be drawn in upon the Schoonspruit blockhouse line, specially reinforced.
The moon was full, and Col. Rochfort's men marched through the night, making Wolmaranstad by 3.30 a.m. There the black masses of troops closed up and dismounted, till the whole slope by the townlet was covered with horses and men. Then the columns separated out to take up their positions in the line.
Major Gilbert and Major Driscoll again worked together. At dawn, Driscoll's, who were leading, captured twelve Boers asleep round their wagons; they were an outpost of Delarey's, and they had no idea that any British could be in the vicinity. They said that a commando of Delarey's was ten miles ahead. This commando, however, managed to slip through between two columns. Through the day the net was drawn tighter, and by the evening of the 23rd Major Gilbert and his men had ridden over 60 miles in twenty-one hours. At six o'clock they bivouacked in the rain in some scrub at Matjespruit. There had been a heavy hailstorm during the afternoon.
On the next afternoon Klerksdorp was reached. Some hundreds of Boers had been caught altogether, besides three 15-pounders, two pom-poms, and a quantity of ammunition. Perhaps the greatest effect produced, however, was upon the nerves of the Boers. They got into a state of "nervous tension," as they never knew when or where the British would turn up next. A district miles away from the nearest troops in the evening was swarming with columns in the morning. The absolute abandonment of transport by the British had been the key to the situation.
On the evening of the following day Col. Rochfort's columns started to return to Commando Drift. They marched 30 miles during the night, and got to the Drift the next evening, having covered 150 miles in four days. The lights of the camps that stretched along the river for a mile or more shone through the trees like the lights of a town.
On the way in, two Africander guides of the Intelligence Department had ridden on ahead of the columns, and, coming up to a farm, were taken by the woman there for Boers. She gave them seven rounds of ammunition (all she had, she said) and told them they must not stay, as there were thousands and thousands of Khakis on the river—more than she had ever seen—with Lord Roberts and Lord Kitchener. Asked how she knew Lord Roberts was there, she produced a photograph of him out of a packet of cheap cigarettes, and said she recognised him as he rode through.
On the 29th of March the Sussex column was finally broken up. It had been ten months in existence not counting the months of convoy work; it had covered thousands of miles. It had had its days of success, and it had come through its black hour of tribulation. For some months it had been dwindling in numbers, more and more men becoming dismounted and being left at the various bases. The column had done its work.
The remaining mounted men were turned into an M. I. Company under Captain Montrésor, and attached to Col. Western's column, of which Major Gilbert was made second in command. The dismounted men were sent to Hoopstadt, at which place the officers, men and stores left behind at Vlakfontein had arrived.
From this time until the declaration of peace on June 1st, the dismounted men worked between Hoopstadt, Bloemhof and the line, sometimes as escort to convoys, sometimes as stops for drives. The mounted company joined in the latter, of which the most important took place on the 9th of June and following days. Col. Rochfort's columns moved to Schweizer Renecke, where they surprised some Boers, capturing sixty. They then formed, in conjunction with Gen. Ian Hamilton's columns from the north, a line in single rank 50 miles long. For the next three days this line moved west, the men sleeping in their positions at nightfall. The sight, when an extended view could be got, was a strange one. As far as the eye could reach the line of mounted men stretched away, here dipping into a valley, there topping a rise. There were some 21,000 troops driving.
