"I mock at you, I laugh at you, Inglese," he cried. "You dare threat us? Who has the greater army, I like to know? You take the fort! Bah!

Is it a dog's kennel? You talk to me, eh? I talk to you, so; I say, you insolent puppy; you no take fort; no. You go back to your camp, and in a little while our army will come to you and drive you into the water. Bah, I spit at you!"

Tom paid no heed to the furious man's insolence. He turned quietly towards Mustapha, and with unruffled courtesy said:

"Have I your final answer?"

His manner evoked a corresponding politeness from the Arab, whose reply, as translated by Mboda, was simply:

"I have sworn an oath. I will not surrender. I will fight you."

Tom decided to make one more appeal. Addressing the hakim, who had stood hitherto gravely silent, he said in German:

"Mahmoud, my friend, cannot you persuade Mustapha, to abstain from a hopeless contest? You have all heard of my success till now. You, surely, do not doubt that I shall succeed again? You yourself were kind to me; I should be deeply grieved if, during the struggle that seems inevitable, any harm came to you. Will you not induce your chief to give way?"

The stately hakim looked with kindly eyes upon the young Englishman, whose earnest and friendly tone had touched him. Then he shook his head.

"I am an Arab," he said. "Whether we win or lose, whether we live or die, all rests with Allah. I am Mustapha's man."

"I am sorry," replied Tom, and was about to take leave when De Castro said suddenly:

"You speak French?"

"Yes."

Then, speaking rapidly in that language, De Castro suggested that Tom should give him a safe-conduct for himself and his property. In that case he promised to deliver up the fort; he cared nothing, he said, what then became of the Arabs. Tom looked at the traitor with silent scorn.

The Portuguese quailed for a moment; then, his face livid with rage and mortification, he glared at Tom's accusing face, and burst out in Swahili, clearly for the benefit of Mustapha, who was looking at him with suspicion:

"Have you your answer, puppy? Will you go? To-morrow I will have you in the fort, tied to a post, and you shall not escape me again. Now I make you my bow."

With a low mocking inclination he turned away. Tom bowed to the Arabs, and also turned. At that instant De Castro wheeled round, whipped a revolver from his pocket, and fired point-blank at Tom. The shot missed, but struck Mwonda, immediately in front of Tom, and wounded him in the shoulder. The giant turned round with a roar like a bull's, and sprang towards his treacherous a.s.sailant. De Castro pointed his revolver again at Tom; the bullet whistled past his ear. Cursing his ill-luck, the Portuguese turned just in time to elude the raised arm of Mwonda, and at that moment a volley rang out from the camp; one of the bullets sped past Tom and hit De Castro's left arm. The revolver fell from his right hand, and with a howl of agony and rage he bolted up the field into the fort. Mustapha disdained to run; he walked back in his stately way, and escaped. The hakim was not so fortunate. As he was returning to the fort, a little behind Mustapha, he was shot through the back, and fell. Tom sprang to the fallen man, and at the same moment Mbutu, at the head of a hundred musketeers, came running out of the camp in desperate fear for his master's safety. Tom reached the hakim, lifted him in his arms, carried him a few steps, called Mboda to a.s.sist him, and hurried with the heavy burden towards his own camp just as a volley flashed from the fort. The shots were hasty and ill-directed, and, covered by Mbutu's company, who halted and poured a steady fire towards the fort, Tom and his two companions safely reached the shelter of their entrenchments, and, panting with their exertions, laid the unconscious hakim on the ground. Mbutu returned with his men immediately afterwards, the whole incident having occupied little more than a minute. Tom had much trouble in restraining his infuriated troops from rushing upon the fort without further delay.

"Wait, my men," he cried; "they shall pay to-morrow." And he turned to examine the hakim's wound.

Mahmoud died at dawn, having recovered consciousness for but one brief moment, during which he pressed Tom's hand, smiled at him with the same grave, wise smile, and murmured: "It is the will of Allah; all is well."

Tom buried him on a little hillock at the lake side. Then he set about his preparations for the final struggle, with a fierceness foreign to his nature. His heart was filled with bitter resentment against the dastard whose treachery had brought unnecessary death upon an innocent man. "Within twenty-four hours it shall be finished," he said to himself with grim resolution.

He did not underrate the difficulty of the task before him. From the number of canoes that had met him on the lake, and the number of men in them, he calculated that the garrison in the fort amounted to at least a thousand men. The five hundred left by Rumaliza had been increased by fugitives from his own and from De Castro's force, and further by a completely equipped force of two hundred and fifty men who had returned, a few days before Tom's arrival, from an expedition northwards. With such a garrison, and the advantage of a strong position behind a glacis which could be swept from end to end by rifle fire, the fort was obviously secure against direct attack with a force of only eleven hundred and fifty men. Investment, again, would not only be a very protracted affair, but was likely to fail, for the Arabs were no doubt well provisioned, while Tom had only a scanty stock of food. If they could have been deprived of water a siege would soon terminate, but Tom had learned from the prisoners that a constant supply was obtained from a deep well within the fort. The only method left was a night-attack, and after his previous experience De Castro would unquestionably be on his guard against surprise. Still, it seemed the only possible course, and Tom, after breakfast, sat down to think out the points involved.

The most common danger attending a night-attack--the risk of losing the way and stumbling on the enemy unawares--was absent. Further, the attackers could approach the palisade under cover of darkness with less risk of suffering serious loss by rifle fire than if the a.s.sault were made by daylight. By making feints in two or three quarters Tom could throw his main force in overwhelming strength on the real point of attack. And, last consideration of all, the Arabs had an inveterate repugnance to fighting by night, whereas his own troops had by repeated successes gained confidence in this respect. The only great disadvantage was that, unfamiliar as he was with the interior of the fort, he could not be sure in the darkness of directing the attack towards the most vulnerable points; but this drawback might be neutralized by a simple means he had at hand.

A night-attack was therefore decided on. Tom prayed that the night might be dark. He called up one of the prisoners, and made him draw a rough plan of the fort on a leaf torn from his pocket-book. Then he sent one of the redoubts to the mainland to fetch further stores and to bring back a number of carriers with knives and axes. When these arrived he set them to work in cutting a path through the bush on the east side of the island in order that his troops might move rapidly from place to place without being seen. While the carriers were engaged in this task a sudden shout from the south apprised him that something was happening in that quarter. In a few moments a messenger came up with the news that the enemy had made a sortie from the south gate with the evident intention of capturing the canoes, and had driven back the post placed between the plantations and the belt of copse. But this move had been already provided against. When the Arabs reached the sh.o.r.e they saw, to their chagrin, that the canoes lay two hundred yards out on the lake, under the protection of one of the floating forts. Tom sent three hundred men under the kasegara to intercept the enemy as they returned.

The Bahima placed themselves just within the copse in a line parallel to the path leading to the gate, and poured in a hot fire at the Arabs as they hastened back. Mustapha, in the fort, was on the alert; he threw out a large force to cover the retreat of his men, and but for this it seemed likely that the sortie-party would have been cut off from their base and annihilated. As it was, they lost heavily, and no similar organized attempt was made during the rest of the day, though occasional shots were fired from the fort as if to show that the enemy was not napping.

Taking advantage of the freedom from serious interference, Tom devoted himself to his plan of operations. He decided that the real attack should be made, not from his camp, east of the fort, as the Arabs would no doubt expect, but from the south. The katikiro with two hundred men would make a feigned attack from a point north of the fort, and the kasegara with another two hundred would demonstrate vigorously against the east. Each of these feigned attacks would be accompanied with heavy rifle-fire, and, while they were in progress, Tom himself would lead a strong force against the southern portion of the palisade, from which he expected that most of the defenders would have been drawn off towards the apparent danger north and east.

At nightfall, then, Tom called his officers together and explained his plans. He was somewhat surprised to see Mwonda among them, for the giant had been badly wounded in the right shoulder. He was still more surprised to learn that the heroic negro had got a companion to cut the bullet out of his flesh, and had borne the terrible pain without so much as a groan. He came now, with his right shoulder bound up, and his musket in his left hand, determined to wreak vengeance in person for the treacherous blow dealt him.

"You are a brave fellow, Mwonda," said Tom. "You shall be in command of the northern force, and the katikiro shall stay with me. The kasegara will attack first, on the east, when I send him word, an hour before dawn. When you hear his rifles in play, Mwonda, you will make a sham attack on the north gate. Understand, you are both to keep up a heavy fire, and shout as loud as you like; but you are not to make a real attack until you get orders from me."

Since his arrival on the island Tom had taken no pains to preserve silence in the camp, and on this night he ordered companies of a hundred men, in addition to the usual sentries, to be kept awake in turn, each for an hour, so that their chatter might delude the enemy and cover up any sounds made by his troops as they moved to their positions. Two hours before dawn the movements began. Mwonda led his men northwards, being instructed to march as silently as possible. Tom, accompanied by Mbutu and Msala, went southwards with seven hundred men, leaving the kasegara in charge of the camp with orders to keep his men talking until he received the signal for beginning the sham attack. With Tom's men went fifty carriers with scaling-ladders, and before starting he ordered one man in five to take a fire-ball in addition to his gun or pike.

When they reached the position he had decided on, he briefly explained what they were to do. Then he turned to Mbutu and the katikiro and said quietly:

"If I fall, press home the attack with all your might. The men will follow you if you only show them strong leadership. And, Mbutu, when the fight is over, if I am not alive, I trust to you to make your way to Kisumu, and tell my uncle, if he is there, or the English commander if he is not, all that has happened to me. That is my last request."

Then he sent a messenger to the kasegara. Ten minutes later a sharp volley was heard in the direction of the camp, accompanied by savage yells. Immediately afterwards shouts and the crackle of rifles were heard, less distinctly, from the north.

"My men," said Tom, "now is our turn. Go quietly through the copse, make a rush to the foot of the slope; scramble up, on hands and knees if you must, and make for the palisade. No firing, mind; nothing but bayonets and pikes at first. Don't fire till I give the word. Now, advance!"

Two hundred men being left in reserve, Tom's little force consisted of five hundred musketeers and pikemen, and the fifty carriers with the scaling-ladders. These latter held the ladders in front of them as a partial protection from rifle fire. The whole force moved quickly through the woodland, gained the bottom of the glacis with a rush, and began the ascent. The front ranks were half-way up before their presence was discovered. Then a brisk fusillade broke out from the fort, and several men fell. The rest threw themselves on their hands and knees, and finished the ascent at a scramble. The point made for was a few yards to the left of the gateway. While the bullets were flying erratically over the palisade, the carriers placed their ladders against it, and as, owing to the slope, they stood somewhat insecurely, Tom ordered four men to hold each while the rest mounted. In hardly more than a minute a hundred men were within the palisade, to find themselves exposed to cross-fires from the gate and from a line of fencing thrown across from the inner stockade to the outer, thus dividing the s.p.a.ce between them into compartments. But faster than the gaps were made they were filled by fresh men swarming over the fencing. Tom was over among the first. He ordered some of the ladders to be hauled across and planted against the inner palisade, now more strongly defended by reinforcements which the first alarm had drawn from north and east. The Arabs were firing not only over the palisade, but through loopholes in it. Luckily the invaders had already spread, so that there were no close ranks to be decimated by the fusillade, and in the darkness and the flurry the defenders' fire was necessarily ill-aimed.

"Light fire-b.a.l.l.s!" cried Tom in a clear voice. In half a minute twenty flaming b.a.l.l.s whizzed through the air and over the inner stockade, lighting up the interior of the fort with its huts and tents, and showing the loopholes in the fencing. These became the target for Tom's best marksmen as he now at last gave the order to fire. Bullets flew fast; war-cries seemed to split the air; the defenders were already verging on panic. Some were making desperate attempts to extinguish the fire-b.a.l.l.s, only to become the marks for more of those flaming missiles.

A hut was already alight, and Tom's men were now swarming almost unchecked over the palisade. A few fire-b.a.l.l.s had speedily cleared out the enemy from the cross fence, and this position was immediately occupied by the Bahima. The katikiro, at Tom's orders, had led a party of men with scaling-ladders to the left along the enclosure between the palisades to a point opposite the eastern gate, and cries from that quarter told that a position had been occupied there. Thus in less than half an hour three positions were held by the attackers. Several huts in the interior of the fort were in flames, and the defenders were rushing hither and thither, exposed to destructive rifle-fire from their own palisades.

Tom had already sent instructions to the kasegara and Mwonda to cease their demonstrations as soon as they saw a strong light in the fort, and to move towards each other and join forces. When the junction was made, and as soon as carriers with scaling-ladders arrived, they were to make a vigorous attack in real earnest at a point midway between their former positions, that is, from the north-east. Profiting by the respite from attack on the north and east, Mustapha and De Castro, who had given their orders. .h.i.therto from the very centre of the fort, now began to get their men into some sort of order, rallying them around Rumaliza's house. Hardly had this been done when a great din to the north-east announced that an a.s.sault was commencing there.

"Over into the fort, men!" cried Tom as soon as he heard the welcome sound. Up they clambered, up the ladders already planted against the inner palisade, up and over, hundreds of eager men pouring into the enclosure, no obstacle now between them and their enemy. Brought to bay, the Arabs fought desperately, dodging behind huts, seizing every point of vantage, knowing well that their former victims would spare none of them. Many of their dwellings were now ablaze, and in the brilliant illumination scores of the Manyema could be seen using the Bahima's scaling-ladders to escape over the palisades into the darkness.

The Arabs themselves held their ground more stubbornly, but their enemies were now closing all round them. The attackers under Mwonda had met with but feeble resistance, for the majority of the defenders at the north-east had been withdrawn to withstand the earlier attack from the south. Mwonda himself, whose bellow could be heard above all other noises, plunged along at the head of his men, swinging his heavy musket, disdaining the few bullets that fell around him, and searching everywhere for the wretch who had shot him when he was unarmed.

As the s.p.a.ce between the stockades filled with the exultant Bahima, hundreds of the enemy flung down their arms and begged for mercy.

"Spare all who surrender!" shouted Tom, and the order was repeated through the ranks of his men. Some of the enemy, however, scorning to yield, fought with the courage of despair to the bitter end, and were shot down or speared after they had themselves done great execution on the now crowded ranks of their a.s.sailants. Tom had several times caught sight of Mustapha moving about among his men, but not once had De Castro been visible. The centre of the fortress was occupied by a range of buildings of more solid construction than the huts nearer the stockade.

It was Rumaliza's own house, a substantial stone structure of two stories, with a veranda running around the upper story, obviously an effort after comfort amid savage surroundings, and modelled on the residences of merchants on the coast. Tom, joined by Mwonda, and accompanied by Mbutu and the katikiro, led a small force of Bahima towards this building, in which he conjectured that some of the enemy, perhaps De Castro himself, had taken refuge. The walls were loopholed, and from these, as well as from the veranda, a hot fire met the little group. Two of the men fell. The door was of stout oak.

"We must burst it in," said Tom. "Find a stout beam, Mbutu. Quick!"

Mbutu darted away, and soon returned with three men hauling a ma.s.sive beam, obtained by cutting down the post supporting the roof of a neighbouring hut. Just as they reached the door one of the three men was shot through the heart, and a bullet from above struck Tom in the thigh.

"I'm hit, Mbutu," he said. "Bind this strip of linen tightly round my leg; there's the place."

"Come away, sah, come away!" cried Mbutu pleadingly.

"Not yet. This door must come down first. Msala, batter the door in.

Come, lift the battering-ram, men! Now then, one, two, three--that's it! The door's started. Now again, one, two, three! Ah! it's down.

In you go, men! I'm coming!"

As the door fell in with a crash, the party of twenty men poured in, Tom limping painfully after them. There was no resistance; the room was empty.

"Up the stairs!" cried Tom. "Don't waste a minute!"

Mwonda was already springing up the ladder in the corner of the room, taking three steps at a time. In twenty seconds he came tumbling back into the room, yelling that the upper floor also was empty. At that moment there was a shout from the rear of the house. Bushing out, the Bahima found themselves in a sort of yard. The gate was open, and beyond were evidently outhouses and store-rooms. At one side of the yard was a man chained to a post, and yelling with all his might. By the feeble light from the now diminishing conflagration outside, Tom as he hastened up recognized Herr Schwab. The recognition was mutual.

"Out, out!" cried the German. "Zey are outside."

"Cut him loose," cried Tom to one of his men as he pa.s.sed by, heedless of further cries from the German.

Mwonda and Msala were already in the narrow lane beyond the yard. There was no sign of the enemy.

"After them!" cried Tom. "Don't wait for me; I'll follow as quickly as I can."
