He noticed a clump of trees a little to the right, nearer the bank of the river, and made straight for that. As he ran towards it, he came within view of the horsemen working round on the left flank. They immediately wheeled round, and galloped hard in pursuit. But their course brought them below the ridge on which, all unknown to them, Challis and his band lay concealed. As they rode past, within range of about a hundred yards, a sudden volley on their right flank sent some of them reeling to the ground. The rest, taken all aback, swerved to the left, and dashed frantically away towards their main body, who had now become aware that the hillock was deserted, and were surging up it. "Well done, Tom!" The ringing words came faintly from the rear. Challis brushed his sleeve across his sweating brow, and ordered his men to run with him. It was something to have gained half-an-hour without the loss of a man. CHAPTER XII A STAMPEDE Taking advantage of the flight of the flanking party, Royce pushed on as soon as he was rejoined by Challis, in order to gain a denser portion of the forest, where the pursuers would be much more impeded than his own men. He had two other reasons. The carriers had gone on by themselves, without guidance, and it was probable that they would take a wrong direction. Further, there was a possibility that in the absence of the white men they would be seized with panic, and stampede, leaving their loads. The Hausas could not at once carry and fight, and all the fighting strength would be needed if the enemy still came on. It seemed that the double check which the Tubus had suffered had daunted them, at any rate for the time being; for Royce, looking back, saw no sign of their having crossed the ridge. About ten minutes later he came up with the carriers, who, on reaching the edge of the thicker woodland, had prudently halted from fear of losing the way. John again went ahead with them as guide, Challis following at a short interval with his section, and Royce with the remainder acting as rearguard. The march through the forest entailed a disadvantage which almost outweighed its advantages from the point of view of security. It was impossible to see what the enemy were doing. They might have given up the chase; they might be pressing on in the rear; they might still be working round on the flanks, avoiding the woodland area, and outspeeding the fugitives on more open ground. For this reason Royce forced the pace as much as possible. From his rather hazy recollection the fort was still five or six miles away, a distance which he could scarcely hope to cover under three hours. By degrees the forest thinned, and after about two hours' marching it opened upon the lake which Royce had skirted on his return from the village. By this time everybody was tired and hungry. "We must take a spell of rest," he said to Challis. "I think it's scarcely likely the Tubus have come through the forest after us."
