Then Otter rose upon his hands and knees, and his face looked fierce in the faint light.
"Baas," he whispered, "shall we----" and he drew his hand across his throat.
Leonard thought awhile. His rage was deep, and yet he shrank from the slaughter of sleeping men, however wicked. Besides, could it be done without noise? Some of them would wake--fear would sober them, and they were many.
"No," he whispered back. "Follow me, we will cut loose the boats."
"Good, good," said Otter.
Then, stealthily as snakes, they crept some thirty yards to where the boats were tied to a low tree--three canoes and five large flat-bottomed punts, containing the arms and provisions of the slave-dealers. Drawing their knives they cut these loose. A gentle push set them moving, then the current caught them, and slowly they floated away into the night.
This done they crawled back again. Their path took them within five paces of where that half-breed ruffian lay who had begun the talk to which they had listened. Leonard looked at him and turned to creep away; already Otter was five paces ahead, when suddenly the edge of the moon showed for the first time and its light fell full upon the slaver"s face. The sleeping man awoke, sat up, and saw them.
Now Leonard dared not hesitate, or they were lost. Like a tiger he sprang at the man"s throat and had grasped it in his hand before he could even cry aloud. Then came a struggle short and sharp, and a knife flashed. Before Otter could get back to his side it was done--so swiftly and so silently that none of the band had wakened, though one or two of them stirred and muttered in their heavy sleep.
Leonard sprang up unhurt, and together they ran, rather than walked, back to the spot where they had left Soa.
She was watching for them, and pointing to Leonard"s coat, asked "How many?"
"One," answered Otter.
"I would it had been all," Soa muttered fiercely, "but you are only two."
"Quick," said Leonard, "into the canoe with you. They will be after us presently."
In another minute they had pushed off and were clear of the island, which was not more than a quarter of a mile long. They paddled across the river, which at this spot ran rapidly and had a width of some eight hundred yards, so as to hide in the shadow of the opposite bank.
When they reached it Otter rested on his paddles and gave vent to a suppressed chuckle, which was his nearest approach to laughter.
"Why do you laugh, Black One?" asked Soa.
"Look yonder," he answered, and he pointed to some specks on the surface of the river which were fast vanishing in the distance. "Yonder go the boats of the slave-dealers, and in them are their arms and food. We cut them loose, the Baas and I. There on the island sleep two-and-twenty men--all save one: there they sleep, and when they wake what will they find? They will find themselves on a little isle in the middle of great waters, into which, even if they could, they will not dare to swim because of the alligators. They can get no food on the island, for they have no guns and ducks do not stop to be caught, but outside the alligators will wait in hundreds to catch _them_. By-and-by they will grow hungry--they will shout and yell, but none will hear them--then they will become mad, and, falling on each other, they will eat each other and die miserably one by one. Some will take to the water, those will drown or be caught by the alligators, and so it shall go on till they are all dead, every one of them, dead, dead, dead!" and again Otter chuckled.
Leonard did not reprove him; with the talk of these wretches yet echoing in his ears he could feel little pity for the horrible fate which would certainly overtake them.
Hark! a faint sound stole across the quiet waters, a sound which grew into a clamour of fear and rage. The slavers had awakened, they had found the dead man in their midst mysteriously slain by an invisible foe. And now the clamour gathered to a yell, for they had learned that their boats were gone and that they were trapped.
From their shelter on the other side of the river, as they dropped leisurely down the stream, Leonard and Otter could catch distant glimpses of the frantic men rushing to and fro in the bright moonlight and seeking for their boats. But the boats had departed to return no more. By degrees the clamour lessened behind them, till at last it died away, swallowed in the silence of the night.
Then Leonard told Soa what he had heard by the slaver"s fire.
"How far is the road, Black One?" she asked when he had finished.
"By sundown to-morrow we shall be at the Yellow Devil"s gates!" answered Otter.
Two hours later they overtook the boats which they had cut adrift. Most of them were tied together, and they floated peacefully in a group.
"We had better scuttle them," said Leonard.
"No, Baas," answered Otter, "if we escape we may want them again. Yonder is the place where we must land," and he pointed to a distant tongue of marsh. "Let us go with the boats there and make them fast. Perhaps we may find food in them, and we need food."
The advice was good, and they followed it. Keeping alongside of the punts and directing them, when necessary, with a push of the paddles, they reached the point just as the dawn was breaking. Here in a sheltered bay they found a mooring-place to which they fastened all the boats with ropes that hung ready. Then they searched the lockers and to their joy discovered food in plenty, including cooked meat, spirits, biscuits, bread, and some oranges and bananas. Only those who have been forced to do without farinaceous food for days or weeks will know what this abundance meant to them. Leonard thought that he had never eaten a more delicious meal, or drunk anything so good as the rum and water with which they washed it down.
They found other things also: rifles, cutla.s.ses and ammunition, and, better than all, a chest of clothes which had evidently belonged to the officer or officers of the party. One suit was a kind of uniform plentifully adorned with gold lace, having tall boots and a broad felt hat with a white ostrich feather in it to match. Also there were some long Arab gowns and turbans, the gala clothes of the slave-dealers, which they took with them in order to appear smart on their return.
But the most valuable find of all was a leather bag in the breeches of the uniform, containing the sum of the honest gains of the leader of the party, which he had preferred to keep in his own company even on his travels. On examination this bag was found to hold something over a hundred English sovereigns and a dozen or fifteen pieces of Portuguese gold.
"Now, Baas," said Otter, "this is my word, that we put on these clothes."
"What for?" asked Leonard.
"For this reason: that should we be seen by the slave-traders they will think us of their brethren."
The advantages of this step were so obvious that they immediately adopted it. Thus disguised, with a silk sash round his middle and a pistol stuck in it, Leonard might well have been mistaken for the most ferocious of slave-traders.
Otter too looked sufficiently strange, robed as an Arab and wearing a turban. Being a dwarf, the difficulty was that all the dresses proved too long for him. Finally it was found necessary to cut one down by the primitive process of laying it on a block of wood and chopping through it with a sabre.
When this change of garments had been effected, and their own clothes with the spare arms were hidden away in the rushes on the somewhat remote chance that they might be useful hereafter, they prepared for a start on foot across the marshes. By an afterthought Leonard fetched the bag of gold and put it in his pocket. He felt few scruples in availing himself of the money of the slave-driver, not for his own use indeed, but because it might help their enterprise.
Now their road ran along marshes and by secret paths that none save those who had travelled them could have found. But Otter had not forgotten. On they went through the broiling heat of the day, since linger they dared not. They met no living man on their path, though here and there they found the body of some wretched slave, whose corpse had been cast into the reeds by the roadside. But the road had been trodden, and recently, by many feet, among which were the tracks of two mules or donkeys.
At last, about an hour before sunset, they came to the home of the Yellow Devil. The Nest was placed thus. It stood upon an island having an area of ten or twelve acres. Of this, however, only about four and a half acres were available for a living s.p.a.ce; the rest was a mora.s.s hidden by a growth of very tall reeds, which mora.s.s, starting from a great lagoon on the northern and eastern sides, ran up to the low enclosure of the buildings that, on these faces, were considered to be sufficiently defended by the swamp and the wide waters beyond. On the southern and western aspects of the camp matters were different, for here the place was strongly fortified both by art and nature. Firstly, a ca.n.a.l ran round these two faces, not very wide or deep indeed, but impa.s.sable except in boats, owing to the soft mud at its bottom. On the further side of this ca.n.a.l an earthwork had been constructed, having its crest stoutly palisaded and its steep sides planted with a natural defence of aloes and p.r.i.c.kly-pears.
So much for the exterior of the place. Its interior was divided into three princ.i.p.al enclosures. Of these three the easternmost was the site of the Nest itself, a long low thatched building of wood, in front and to the west of which there was an open s.p.a.ce or courtyard, with a hard floor. Herein were but two buildings, a shed supported on posts and open from the eaves to the ground, where sales of slaves were carried on, and further to the north, almost continuous with the line of the Nest itself, but separate from it, a small erection, very strongly built of brick and stone, and having a roof made from the tin linings of ammunition and other cases. This was a magazine. All round this enclosure stood rows of straw huts of a native build, evidently occupied as a camp by the Arabs and half-breed slave-traders of the baser sort.
The second enclosure, which was to the west of the Nest, comprised the slave camp. It may have covered an acre of ground, and the only buildings in it were four low sheds, similar in every respect to that where the slaves were sold, only much longer. Here the captives lay picketed in rows to iron bars which ran the length of the sheds, and were fixed into the ground at either end. This camp was separated from the Nest enclosure by a deep ca.n.a.l, thirty feet in width and spanned at one point by a slender and primitive drawbridge that led across the ca.n.a.l to the gate of the camp. Also it was protected on the Nest side by a low wall, and on the slave-camp side by an earthwork, planted as usual with p.r.i.c.kly-pears. On this earthwork near the gate and little guard-house a six-pounder cannon was mounted, the muzzle of which frowned down upon the slave camp, a visible warning to its occupants of the fate that awaited the froward. Indeed, all the defences of this part of the island were devised as safeguards against a possible _emeute_ of the slaves, and also to provide a second line of fortifications should the Nest itself chance to be taken by an enemy.
Beyond the slave camp, lay the garden that could only be approached through it. This also was fortified by water and earthworks, but not so strongly.
Such is a brief description of what was in those days the strongest slave-hold in Africa.
CHAPTER X
LEONARD MAKES A PLAN
The road which Leonard and his companions were following led them to the edge of the main and southernmost ca.n.a.l, debouching exactly opposite the water-gate that gave access to the Nest. But Otter did not venture to guide them to this point, for there they should be seen by the sentries, and, notwithstanding their masquerade dress, awkward questions might be asked which they could not answer. Therefore when they had arrived within five hundred yards of the gate, he struck off to the left into the thick bush that clothed the hither side of the ca.n.a.l. Through this they crawled as best they might till finally they halted near the water"s edge, almost opposite to the south-west angle of the slave camp, and under the shadow of a dense clump of willows.
"See, Baas," said the dwarf in a low voice, "the journey is accomplished and I have brought you straight. Yonder is the house of the Yellow Devil--now it remains only to take it, or to rescue the maiden from it."
Leonard looked at the place in dismay. How was it possible that they--two men and a woman--could capture this fortified camp, filled as it was with scores of the most wicked desperadoes in Africa? How was it possible even that they could obtain access to it? Viewed from far off, the thing had seemed small--to be done somehow. But now! And yet they must do something, or all their labour would be in vain, and the poor girl they came to rescue must be handed over to her shameful fate, or, if she chose it in preference and could compa.s.s the deed, to self-murder.
"How on earth!" said Leonard aloud, then added, "Well, Otter, I can tell you one thing. I have come a long way on this business, and I am not going to turn my back to it now. I have never yet turned my back on a venture and I will not begin with this, though I dare say that my death lies in it."
"It is all in the hand of to-morrow," answered Otter; "but it is time that we made a plan, for the night draws on. Now, Baas, here is a thick tree shaded by other trees. Shall we climb it and look down into the camp?"
Leonard nodded, and climbing the tree with ease, they peeped down through the leafiest of its boughs. All the camp lay beneath them like a map, and Otter, clinging monkey-wise to a branch, pointed out its details to Leonard. He had been a prisoner there, and the memories of prisoners are long.
The place was peopled by numbers of men in strange costumes, and of different nationalities; dealers in "black ivory" of various degree.
