Two hours later all was ready for a start, and just before sunset the corps rode out of Ladysmith. They kept a sharp look-out as they went, but saw no signs of the enemy, and crossing the Tugela by the bridge near Colenso, halted there for the night. Here Captain Brookfield reported his arrival to the officer in command of the troops, and on the following day Chris and his friends rode on to Estcourt. They had seen some parties of mounted men in the far distance, but none had come near them, and as the military authorities were well aware of the Boers being in the vicinity, there was nothing to be gained by scouting. But it was now decided that they were in advance of the point that any large number of the enemy were likely to reach, and might therefore strike across the country and resume what they considered their regular work. They added to their stores several articles whose want they had felt, had slits made in the waterproof sheets, and covers sewn on to close the holes when they were used for tents, and had some triangular pieces of the same material made to buckle on so as to close the rear of the tents, which had before been open to the wind and rain. They had employed much of their spare time in training their horses and in teaching them to lie down when ordered, and thus share the shelter taken up by their masters, behind rocks or a wall.
The officer commanding the small force at Estcourt had at first viewed them with some suspicion, but Colonel Yule had purposely left open the letter with which he had furnished Chris, so that it could be shown to any officers commanding posts or detached forces, and its production now caused his cold reception to be converted into a warm welcome. Riding across country they met more than one farmer trekking with his cattle and belongings towards the ferry across the Mooi river. These reported that the Boers had overrun the whole of the country north of the Tugela, and that some parties had already crossed at the ferry on the road between Helpmakaar and Greytown. Fugitives had come in from the villages on the other side, and complained that the Boers were looting everywhere, and had driven off thousands of cattle and numbers of horses, and had everywhere wantonly destroyed the furniture and everything they could not carry off, in the farmhouses they visited.
A vigilant look-out was kept as the scouts advanced. On the second day after starting they encamped on a slight elevation near Mount Umhlumba, and early next morning they saw a party of some twenty Boers riding in a direction that would bring them within rifle-shot of their camp. All were at once on the alert.
"We will not go out and attack them," Chris said to the lads who were running towards their horses. "That would mean that though we might kill all of them, half of us would probably be shot. We will ambush them. Get the picket ropes loose and the bridles on ready for mounting, and then leave the horses in charge of the natives where we camped. They will be out of sight there. When you have done that take your places quietly among the rocks. Do you, Capper and Carmichael, put yourselves twenty or thirty yards apart; you are our best shots. When the Boers get within a thousand yards, which is as near as they will do if they keep the line they are going, open fire upon them and keep it up steadily, but not too fast. When they see that only two men are firing they will think that you are a couple of farmers whose place they have plundered, and who are determined to have their revenge. You are safe to hit some of them, and the others will decide upon wiping you out, and will probably leave their horses and crawl up in their usual style. When they get close it will be our turn. I don't think many of them are likely to get away."
His orders were carried out, and five minutes later the two rifles flashed out one after another. The Boers were riding in a clump. One was seen to fall, and the horse of another gave a violent plunge.
"Very good," exclaimed Chris, who, like the rest, was lying down behind a rock. "Don't fire too fast. Wait half a minute, and then each take another turn, one a little time after the other." The man who had fallen was instantly picked up by one of his comrades, and all rode off at full gallop, but before they could get beyond the range of the Mausers each of the lads had fired two more shots. No more of the Boers dropped, but the watchers, who had their glasses directed upon them, thought by their movements that two had been hit. The Boers, when the firing ceased, stopped, and for some little time remained clustered together. Then they took a long sweep round to a point where the ground was broken, and a shallow donga ran up in a direction that would bring them within a hundred yards of the position occupied by their hidden assailants. There they were seen to dismount, and, after some talk, leaving all the horses in the charge of one man, probably one of the wounded, they entered the donga. Its course was irregular, and once or twice the two lads were able to get a shot at them. The Boers did not return the fire but hurried past the exposed points. As they approached a head was occasionally raised above the bank to view the position, and then disappeared again. The ground between the camp and the nearest point of the donga was thickly strewn with boulders, with bushes growing between them. The lads had all shifted their position to this side.
"Don't open fire till I give the order," Chris said quietly. "We have got them now."
Except for a slight movement of the bushes, it would not have been known that the Boers had left the donga. Once or twice Capper and Carmichael caught a momentary glimpse of one of them, but held their fire, as Chris had said.
"Let them come within twenty yards, then both fire at once, whether you catch a glimpse of them or not. Thinking that your rifles are discharged, they will all jump up and make a rush. Then it will be our turn."
