The 22nd was comparatively quiet. The situation was not improving. Five miles of rough ground had been won in as many days' fighting, but the force was becoming lengthened out and the line weaker. Lyttleton's force had to guard the line from Potgieter's Drift to Warren's right against any attempt of the Boers to cut the lines of communication. Woodgate was similarly employed in keeping the line from Trichardt's Drift to Warren's left, and it became increasingly evident that not much further progress could be made until the left of the advance was protected by the establishment of guns on the great hill. It was then, on the 23rd, decided that Woodgate's brigade should assault Spion Hop that night. It was known that it was not strongly held. Starting at six o'clock, the column made its way slowly and with vast difficulty up the ascent. This was everywhere rugged and rocky, and in many places so precipitous that men had to be pushed or pulled up by their comrades. Colonel Thorneycroft led the way with a few men, finding out the spots at which an ascent was practicable, and scouting on either side to discover if Boers were hidden; behind him followed Woodgate leading his men. He was in bad health and quite unfit for such a climb, but in spite of remonstrances he had insisted upon going, although he was obliged to be assisted at the more difficult places. The distance was not more than six miles, but it was not until nearly ten hours after starting that the summit was gained. The hilltop was enveloped in mist, and they were unseen until the Lancashire Fusiliers, who were leading, were within fifty yards of the top. Then a Boer challenged them, and directly fired his rifle. Almost instantly a dozen of his comrades joined him, and bringing their magazines into play opened a fierce fusillade. But the aim was hurried, they could scarce see their foes, and the Lancashire men, cheering loudly, rushed up to the crest without loss. The Boers did not await their arrival; only one of them was bayoneted before he turned to fly, and but two or three were overtaken by the eager soldiers. As soon as the Boers had gone, the troops set to work to construct breastworks to hold the spot they had gained against any attempts of the Boers to recapture. The ground was too rocky for digging, and the stones that were scattered thickly about were used for the purpose; but long before the breastwork could be completed a dropping fire was opened by the enemy. The morning was gray and misty, and the clouds hung heavily on the hilltop. As these cleared off slowly, it could be seen that the position was less favourable than it had seemed, for the flat crest extended some distance beyond the point they had entrenched, and from the rocks and low ridges a hot fire broke out. Before the mist cleared off, the Boers had crept up in considerable force, and were, it was evident, preparing to retake the position that had been wrested from them.
