"There's the blockhouses at the corners, sorr."

"You're right. They are going to fire the blockhouses. I'm sorry now I didn't make 'm of stone as I intended. But we had enough trouble with the wall, and the natives are so little used to stonework that perhaps after all they'd have made a poor job of it."

"Sure, I don't see how they are going to get near enough to do any damage, sorr. They can't come up under fire. Do the spalpeens think they'll catch us napping, begore?"

"Can't say, Barney. We must wait and see. The sentries are arranged for the night, eh?"

"They are that, sorr. 'Tis mighty hard to keep the n.i.g.g.e.rs awake; not wan uv 'm but would see the inside uv the guard-room pretty often if they were in the Irish Fusiliers. But Samba and me just take turns to go the rounds all night and keep 'm stirring, sorr; and 'twould be a lucky man that got across into this place widout a crack over the head."

The full purpose of Elbel was seen earlier than Jack had expected. A little before dawn Makoko, who had been on duty at the gate in the northern wall, hurried down to say that he had heard a sound as of a number of men marching for some distance up the hill above the fort.

Jack accompanied him back, gently reprimanding him on the way for leaving his post. Judging by the sounds, there was unquestionably a large body of men on the move. They were approaching as quietly as negroes can; it is not an easy matter to persuade a force of black men to keep perfect silence.

While Jack was still with Makoko, another man came running up from the southern end of the fort and reported that he had heard the sound of many men advancing up the stream. Clearly a serious attack was intended at last. Sending word to Barney to remain on the _qui vive_ at the southern wall, Jack waited anxiously for the glimmering light of dawn to reveal the enemy.

At last he could see them. They took little pains to conceal themselves. Elbel's riflemen were a.s.sembling on the ridge of the slope above. Among them were men carrying each a small barrel on his shoulder. They must have made a wide circuit from their camp below so that their movements might not be suspected until they were well in position.

The word was rapidly pa.s.sed round the fort. In a few seconds every man was at his appointed place. The women and children had been bidden to remain in their huts, for a part of the enclosure being exposed to fire from the slope above, it would have been dangerous for any one to cross. Barney and his men at the southern wall were protected from this fire in their rear by the huts. At the northern wall Jack stood on a narrow platform by the gate, similar to that which he had used at his former camp near Ilola. His riflemen were posted below him, half of them at loop-holes left at intervals in the wall, the remainder just behind, ready to take their places at the word of command.

Jack was surprised to feel how little fl.u.s.tered he was. The responsibilities of the past months had bred self-control, and the capacity to grasp a situation quickly and act at once. And constant work with the same men, whom he had learned to know thoroughly, had created a mutual confidence which augured well for their success when put to the test.

A glance a.s.sured Jack that the main attack, if attack was intended, would be made by the riflemen. The spearmen in the valley of the river were designed to create a diversion and weaken the force available to oppose the princ.i.p.al a.s.sault. Barney could be trusted to hold his own against them.

So little did the enemy, having gained the position above, seek to conceal their movements, that Jack was tempted to salute them with a volley that must have done great execution--the range being scarcely two hundred yards. But Elbel seemed to know by instinct the feeling by which Jack would be animated. He evidently counted on being allowed to fire first. And indeed there was little time for Jack to consider the matter, for even as he made a mental note of the enemy's bravado, he heard a word of command given in a loud voice, and saw Elbel emerge from a small clump of bushes at the edge of the gully. The whole force, except ten men carrying barrels, flung themselves flat on their faces; and Jack had only time to give a rapid warning to his men when a scattered volley flashed from the line of p.r.o.ne figures, the bullets pattering on the stone wall like hail on a greenhouse.

Next moment the men with the barrels dashed forward, some making for the blockhouse above the gully, others for that at the opposite end of the northern wall. Through the clear s.p.a.ce between the two parties the riflemen continued to fire as fast as they could reload. It was clear to Jack that Elbel expected the fire of his two hundred rifles, added to the unexpectedness of the movement, to keep down the fire of the defenders long enough to enable the barrel men to reach the blockhouses. But in this he was disappointed; nothing but a direct and combined a.s.sault on the wall would have gained the time he required.

His rifle fire from a distance was quite ineffective. Jack had ordered his men to keep out of sight, and to fire through the loop-holes in the wall, aiming, not at the riflemen lying on the ground, but at the men sprinting with the barrels. Consequently, when the twenty-five rifles within the fort replied to the first volley, three of the runners fell on the one side and two on the other, their barrels rolling down the slope, some over the edge into the gully, others towards the copse on the east.

The other men, seeing the fate of their comrades, thought of nothing but their own safety. They dropped their barrels and rushed back. But even then they did not take the safe course. Instead of scattering and so lessening the chances of being hit, the two parties joined, and ran up the slope in a compact group. None of them reached the line of prostrate riflemen who were still blazing away ineffectually at the walls and blockhouses. The unfortunate men were caught in full flight and fell almost at the same moment, each man struck by several bullets.

Not till then did Jack allow his riflemen to turn their attention to the enemy's firing line. But one volley was sufficient. Elbel saw that his scheme had totally failed, and his position was untenable.

Not a man of his opponents could be seen; his men had only small loop-holes to fire at, and the average negro is not a sufficiently good marksman to be formidable in such conditions. The defenders, on the other hand, found the enemy an excellent target; for, by some inexplicable piece of folly, Elbel had not ordered them to seek cover behind the many rocks and boulders that were scattered over the ground.

He had lost all his barrel men and several of his riflemen, and within five minutes of the first volley he drew off his troops.

A yell of delight from the stockade followed his retirement. The men slapped their thighs and shouted "Yo! Yo!" until they were hoa.r.s.e.

The women and children poured out of the huts and danced about with wild enjoyment. Imbono's drummer banged with all his might. Some of the boys had made small trumpets of rolled banana leaves, and tootled away to their hearts' content, the sound being not unlike that made by blowing through tissue paper on a comb. Amid all the uproar Pat's joyous bark acclaimed the success.

"Faith, sorr, 'tis real mafficking, to be sure."

"Not quite, Barney. There's n.o.body drunk."

"True, an' the haythen sets an example to the Christian. There are no grog-shops here, praise be, wan at this corner and wan at that, to tempt the poor craturs."

"I only hope they're not shouting too soon, Barney. We haven't done with Elbel yet."

CHAPTER XIX

Breaking the Blockade

Throughout that day Jack was on the alert in antic.i.p.ation of another move on the part of the enemy. But Elbel's men, except the pickets, did not come within sight of the fort, and nothing was heard of them.

Samba wished to go out again on a scouting mission, but Jack refused to allow him to leave the fort in daylight; perhaps in the darkness he might risk a journey once more.

Although the attempt to fire the blockhouses had been foiled, Jack, thinking over the matter, saw that the feat would not have been impossible with the exercise of a little common sense coupled with dash. A second attempt, better organized, might be successful.

"I wish we could guard against the risk," he said to Barney. "We don't want to be continuously on the fidget in case the blockhouses are fired. Yet we can't make 'em fireproof."

"That's true, sorr; still, something might be done to rejuce the inflammation."

"What's that?" said Jack without a smile. To call in question Barney's English was to wound him in the tenderest part.

"Why, sorr, why not drop down some uv them boulders we keep for repairing the wall? If we let them down wid care to the foot uv the blockhouses, close up against the woodwork, 'twould prevent any wan from setting a match to 'm."

"A good idea! we'll try it. Get the men to carry the stones up to the wall. We won't do anything more till it is dark."

When the sun had set, Jack had the stones hauled up to the roof of the blockhouse at the north-west corner, and then dropped down outside, as close to the woodwork as possible. The task was carried on in almost total darkness, only a few rushlights inside the camp preventing the workers from colliding with one another. But it was impossible to contrive that the heavy stones should fall silently, and a shot from up the slope soon told that the enemy had discovered what was going on.

Active sniping for a time gave Jack a good deal of annoyance, and one or two of his men were hit; but he persevered in his work, and had partially accomplished it, when another danger suddenly threatened.

Up the slope, near the position occupied by the enemy in the morning, there appeared small points of light, which moved apparently at random for a few moments, and then came all in one direction, down the hill.

They all started fairly close together, and Jack counted twelve in a line; but soon some diverged from the rest and went off at an angle.

The others came on more and more rapidly towards the fort, jumping occasionally, but keeping on the whole a surprisingly straight course.

"Barrels again!" said Jack to Barney.

Only a few seconds after he had first observed them, they came with a quick succession of thuds against the wall and the half-finished rampart at the foot of the blockhouse, and the points of light spread out into fierce tongues of flame. Lighted matches had been attached to the barrels, and with the bursting of these by the stonework the resin they contained had taken fire. Of the dozen barrels that started, only four had reached their goal, the rest having rolled over the gully on the western slope as had happened during the day.

Jack hoped that his new stonework was sufficient to protect the logs at the base of the blockhouse. But one of the barrels, under the impetus gained in its pa.s.sage down the hill, had jumped the boulders, and breaking as it crashed over, burst into flame within an inch or two of the woodwork. Another line of barrels was starting down the slope.

Jack had called up his best marksmen at the first alarm, and ordered them to take pot-shots at the twinkling points of light, or the figures above, dimly lit up by the matches attached to the barrels. Whether any of the shots got home he could not tell; another set of barrels was trundling down towards the fort.

It appeared to Jack that nothing could save the blockhouse. Burning resin could only be extinguished by a deluge of water, and he had no means of bringing water from the tank in sufficient quant.i.ties. The logs were dry, and, when once fairly alight, would burn furiously.

Barney suggested dropping a heavy boulder on the barrel most dangerously near, but Jack saw that the effect of this would be merely to spread the flames without necessarily extinguishing them. The fire would continue beneath the stone; it would lick the lowest logs, and in a few minutes the whole base of the blockhouse would be ablaze. The imminence of the danger acted as a spur to Jack's resourcefulness. It flashed upon him that there was one chance of saving the fort. Calling to Samba to follow him, he rushed from the roof of the blockhouse down the ladders connecting it with the second floor and this with the ground, and ran at full speed to his hut, where he seized an empty tobacco-tin and searched for a piece of wire. For a few moments he could not lay hands on any, but he then bethought himself of the wired cork of a Stephens' ink-bottle. Wrenching this out, he hastened to the underground magazine where the ammunition was, stored. Samba had preceded him thither with a lighted candle in a little lantern of bamboo.

Among the ammunition was a keg of loose powder sent up by Mr.

Martindale for refilling cartridge cases. While Samba very cautiously held the lantern out of harm's way, Jack, with the brad of a penknife, bored two thin holes in the tin and two corresponding holes in the lid.

Then he inserted the wire and filled the tin with powder. Clapping on the lid and firmly securing it by twisting up the wire, he rushed back to the blockhouse, up to the roof, and cleared out all the men helter-skelter, bidding them go with Samba and bring baskets full of earth to the base of the wall.

The place was now reeking with acrid smoke from the burning resin, great black eddies of it whirling over the roof, stinging Jack's eyes and making him cough and choke. When none but himself was left--for there was some danger in what he purposed--he went to the edge of the roof, and bending over, almost blinded by the fumes, he marked the spot where the flame seemed the fiercest, and dropped the tin into the midst of it. Though he sprang back at once, he had not reached the inmost edge of the roof when there was a loud explosion. The blockhouse rocked; clouds of sparks flew up; and feeling the tremor beneath him, Jack feared he had destroyed rather than saved. But the trembling ceased. He rushed back to the fore edge of the roof and peered over.

As the smoke cleared away he saw no longer a blazing ma.s.s below him; nothing of the barrel was left; but all the ground for many yards around was dotted with little tongues of flame. The force of the explosion had broken up the huge devouring fire into a thousand harmless ones.

But the woodwork near which the barrel had rested was smouldering.

There was still a danger that the blockhouse would burn. While that danger remained Jack felt that his task was not yet done, and he instantly prepared to meet it. Flames from the other barrels that had struck the wall were lighting up the scene. To carry out his purpose involved a great risk, but it was a risk that must be run. Calling to Samba, who had remained nearest at hand, he bade him bring a rope and send Barney and Makoko to him. When they arrived he got them to knot the rope about him, and let him down over the wall on the gully side, which was in deep shadow. Creeping round the blockhouse on the narrow ledge between it and the gully, he called to the men above to lower some of the baskets of earth which had been placed in readiness. As they reached him he emptied them upon the smouldering logs. It was impossible now to keep in the shadow; his every movement was betrayed by the still flaming barrels; and his work was not completed when bullets began to patter about him. His only protection was the rough rampart of boulders which had been thrown over from the roof. But he bent low; it is difficult even for expert marksmen to aim without the guidance of the riflesights, and Elbel's men were far from being experts; Jack finished his job as rapidly as might be, and escaped without a scratch. Then creeping round once more to the gully, he laid hold of the rope and was drawn up into safety.

The other blockhouses meanwhile had been in no danger. That at the north-east corner was defended by the nature of the ground, which sloped so rapidly that a barrel rolled from above could never hit the mark. That at the southeast corner, being at the edge of the precipice, could only be fired by the hand of man, and no man could approach it safely. By averting the danger at the north-west Jack had saved the camp.
