On the 6th De Wet realised his position, and with characteristic audacity and promptness he took means to clear the formidable toils which had been woven round him. The greater part of his command scattered, with orders to make their way as best they might out of the danger. Working in their own country, where every crease and fold of the ground was familiar to them, it is not surprising that most of them managed to make their way through gaps in the attenuated line of horsemen behind them. A few were killed, and a considerable number taken, 270 being the respectable total of the prisoners. Three or four slipped through, however, for every one who stuck in the meshes. De Wet himself was reported to have made his escape by driving cattle against the wire fences which enclosed him. It seems, however, to have been nothing more romantic than a wire-cutter which cleared his path, though cattle no doubt made their way through the gap which he left. With a loss of only three of his immediate followers be Wet won his way out of the most dangerous position which even his adventurous career had ever known. Lord Kitchener had descended to Wolvehoek to be present at the climax of the operations, but it was not fated that he was to receive the submission of the most energetic of his opponents, and he returned to Pretoria to weave a fresh mesh around him.
This was not hard to do, as the Boer General had simply escaped from one pen into another, though a larger one. After a short rest to restore the columns, the whole pack were full cry upon his heels once more. An acute angle is formed by the Wilge River on one side and the line of blockhouses between Harrismith and Van Reenen upon the other. This was strongly manned by troops and five columns; those of Rawlinson, Nixon, Byng, Rimington, and Keir herded the broken commandos into the trap. From February 20th the troops swept in an enormous skirmish line across the country, ascending hills, exploring kloofs, searching river banks, and always keeping the enemy in front of them. At last, when the pressure was severely felt, there came the usual breakback, which took the form of a most determined night attack upon the British line. This was delivered shortly after midnight on February 23rd. It struck the British cordon at the point of juncture between Byng\'s column and that of Rimington. So huge were the distances which had to be covered, and so attenuated was the force which covered them, that the historical thin red line was a massive formation compared to its khaki equivalent. The chain was frail and the links were not all carefully joined, but each particular link was good metal, and the Boer impact came upon one of the best. This was the 7th New Zealand Contingent, who proved themselves to be worthy comrades to their six gallant predecessors. Their patrols were broken by the rush of wild, yelling, firing horsemen, but the troopers made a most gallant resistance. Having pierced the line the Boers, who were led in their fiery rush by Manie Botha, turned to their flank, and, charging down the line of weak patrols, overwhelmed one after another and threatened to roll up the whole line. They had cleared a gap of half a mile, and it seemed as if the whole Boer force would certainly escape through so long a gap in the defences. The desperate defence of the New Zealanders gave time, however, for the further patrols, which consisted of Cox\'s New South Wales Mounted Infantry, to fall back almost at right angles so as to present a fresh face to the attack. The pivot of the resistance was a maxim gun, most gallantly handled by Captain Begbie and his men. The fight at this point was almost muzzle to muzzle, fifty or sixty New Zealanders and Australians with the British gunners holding off a force of several hundred of the best fighting men of the Boer forces. In this desperate duel many dropped on both sides. Begbie died beside his gun, which fired eighty rounds before it jammed. It was run back by its crew in order to save it from capture. But reinforcements were coming up, and the Boer attack was beaten back. A number of them had escaped, however, through the opening which they had cleared, and it was conjectured that the wonderful De Wet was among them. How fierce was the storm which had broken on the New Zealanders may be shown by their roll of twenty killed and forty wounded, while thirty dead Boers were picked up in front of their picket line. Of eight New Zealand officers seven are reported to have been hit, an even higher proportion than that which the same gallant race endured at the battle of Rhenoster Kop more than a year before.
It was feared at first that the greater part of the Boers might have escaped upon this night of the 23rd, when Manie Botha\'s storming party burst through the ranks of the New Zealanders. It was soon discovered that this was not so, and the columns as they closed in had evidence from the numerous horsemen who scampered aimlessly over the hills in front of them that the main body of the enemy was still in the toils. The advance was in tempestuous weather and over rugged country, but the men were filled with eagerness, and no precaution was neglected to keep the line intact.
This time their efforts were crowned with considerable success. A second attempt was made by the corraled burghers to break out on the night of February 26th, but it was easily repulsed by Nixon. The task of the troopers as the cordon drew south was more and more difficult, and there were places traversed upon the Natal border where an alpen stock would have been a more useful adjunct than a horse. At six o\'clock on the morning of the 27th came the end. Two Boers appeared in front of the advancing line of the Imperial Light Horse and held up a flag. They proved to be Truter and De Jager, ready to make terms for their commando. The only terms offered were absolute surrender within the hour. The Boers had been swept into a very confined space, which was closely hemmed in by troops, so that any resistance must have ended in a tragedy. Fortunately there was no reason for desperate councils in their case, since they did not fight as Lotter had done, with the shadow of judgment hanging over him. The burghers piled arms, and all was over.
The total number captured in this important drive was 780 men, including several leaders, one of whom was De Wet\'s own son. It was found that De Wet himself had been among those who had got away through the picket lines on the night of the 23rd. Most of the commando were Transvaalers, and it was typical of the wide sweep of the net that many of them were the men who had been engaged against the 28th Mounted Infantry in the district south of Johannesburg upon the 12th of the same month. The loss of 2000 horses and 50,000 cartridges meant as much as that of the men to the Boer army. It was evident that a few more such blows would clear the Orange River Colony altogether.
The wearied troopers were allowed little rest, for in a couple of days after their rendezvous at Harrismith they were sweeping back again to pick up all that they had missed. This drive, which was over the same ground, but sweeping backwards towards the Heilbron to Wolvehoek line, ended in the total capture of 147 of the enemy, who were picked out of holes, retrieved from amid the reeds of the river, called down out of trees, or otherwise collected. So thorough were the operations that it is recorded that the angle which formed the apex of the drive was one drove of game upon the last day, all the many types of antelope, which form one of the characteristics and charms of the country, having been herded into it.
More important even than the results of the drive was the discovery of one of De Wet\'s arsenals in a cave in the Vrede district. Half-way down a precipitous krantz, with its mouth covered by creepers, no writer of romance could have imagined a more fitting headquarters for a guerilla chief. The find was made by Ross\'s Canadian Scouts, who celebrated Dominion Day by this most useful achievement. Forty wagon-loads of ammunition and supplies were taken out of the cave. De Wet was known to have left the north-east district, and to have got across the railway, travelling towards the Vaal as if it were his intention to join De la Rey in the Transvaal. The Boer resistance had suddenly become exceedingly energetic in that part, and several important actions had been fought, to which we will presently turn.
