Yet a long-range action began on Friday, April 20th, and lasted the whole of the 21st, the 22nd, and the 23rd, in which we sustained few losses, but made no impression upon the enemy. Thirty of the 1st Worcesters wandered at night into the wrong line, and were made prisoners, but with this exception the four days of noisy fighting does not appear to have cost either side fifty casualties. It is probable that the deliberation with which the operations were conducted was due to Rundle's instructions to wait until the other forces were in position. His subsequent movements showed that he was not a General who feared to strike.
On Sunday night (April 22nd) Pole-Carew sallied out from Bloemfontein on a line which would take him round the right flank of the Boers who were facing Rundle. The Boers had, however, occupied a strong position at Leeuw Kop, which barred his path, so that the Dewetsdorp Boers were covering the Wepener Boers, and being in turn covered by the Boers of Leeuw Kop. Before anything could be done, they must be swept out of the way. Pole-Carew is one of those finds which help to compensate us for the war. Handsome, dashing, debonnaire, he approaches a field of battle as a light-hearted schoolboy approaches a football field. On this occasion he acted with energy and discretion. His cavalry threatened the flanks of the enemy, and Stephenson's brigade carried the position in front at a small cost. On the same evening General French arrived and took over the force, which consisted now of Stephenson's and the Guards brigades (making up the 11th division), with two brigades of cavalry and one corps of mounted infantry. The next day, the 23rd, the advance was resumed, the cavalry bearing the brunt of the fighting. That gallant corps, Roberts's Horse, whose behaviour at Sanna's Post had been admirable, again distinguished itself, losing among others its Colonel, Brazier Creagh. On the 24th again it was to the horsemen that the honour and the casualties fell. The 9th Lancers, the regular cavalry regiment which bears away the honours of the war, lost several men and officers, and the 8th Hussars also suffered, but the Boers were driven from their position, and lost more heavily in this skirmish than in some of the larger battles of the campaign. The 'pom-poms,' which had been supplied to us by the belated energy of the Ordnance Department, were used with some effect in this engagement, and the Boers learned for the first time how unnerving are those noisy but not particularly deadly fireworks which they had so often crackled round the ears of our gunners.
On the Wednesday morning Rundle, with the addition of Pole-Carew's division, was strong enough for any attack, while French was in a position upon the flank. Every requisite for a great victory was there except the presence of an enemy. The Wepener siege had been raised and the force in front of Rundle had disappeared as only Boer armies can disappear. The combined movement was an admirable piece of work on the part of the enemy. Finding no force in front of them, the combined troops of French, Rundle, and Chermside occupied Dewetsdorp, where the latter remained, while the others pushed on to Thabanchu, the storm centre from which all our troubles had begun nearly a month before. All the way they knew that De Wet's retreating army was just in front of them, and they knew also that a force had been sent out from Bloemfontein to Thabanchu to head off the Boers. Lord Roberts might naturally suppose, when he had formed two cordons through which De Wet must pass, that one or other must hold him. But with extraordinary skill and mobility De Wet, aided by the fact that every inhabitant was a member of his intelligence department, slipped through the double net which had been laid for him. The first net was not in its place in time, and the second was too small to hold him.
While Rundle and French had advanced on Dewetsdorp as described, the other force which was intended to head off De Wet had gone direct to Thabanchu.
