During the months Desmond had spent in Gheria he had made himself familiar, as far as his opportunities allowed, with the construction of the harbour and the manner of mooring the vessels there. He knew that the gallivats of the Pirate's fleet, lashed together, lay about eighty yards from the head of the jetty under the shelter of the fortress rock, which protected them from the worst fury of the south-west monsoon. The grabs lay on the other side of the jetty, some hundred and twenty yards towards the river--except three vessels which were held constantly ready for sea somewhat nearer the harbour mouth.
He had learnt, moreover, by cautious and apparently casual inquiries, that the gallivats were under a guard of ten men, the grabs of twenty. These men were only relieved at intervals of three days; they slept on board when the vessels were in harbour and the crews dispersed ashore.
In thinking over the difficult problem of escape, Desmond had found himself in a state of perplexity somewhat similar to that of the man who had to convey a fox and a goose and a bag of corn across a river in a boat that would take but one at a time. He could not, with his small party, man a gallivat, which required fifty oarsmen to propel it at speed; while if he seized one of the lighter grabs, he would have no chance whatever of outrunning the gallivats that would be immediately launched in pursuit. It was this problem that had occupied him the whole day during which Diggle had fondly imagined he was meditating on Angria's offer of freedom.
A few moments after their five companions had left them, Desmond and the Gujarati climbed with the agility of seamen along the ties of the framework supporting the jetty, until they reached a spot a yard or two from the end. There, quite invisible from sea or land, they gently lowered themselves into the water. Guided by the dim light which he had noticed, and which he knew must proceed from one of the moored gallivats, Desmond struck out towards the farther end of the line of vessels, swimming a noiseless breast stroke. Fuzl Khan followed him in equal silence a length behind. The water was warm. A few minutes' steady swimming brought them within twenty or thirty yards of the light. The hulls of the gallivats and their tall raking spars could now be seen looming up out of the blackness. Desmond perceived that the light was on the outermost of the line, and, treading water for a moment, he caught the low hum of voices coming from the after part of the gallivat. Striking out to the left, still followed by the Gujarati, he swam along past the sterns of the lashed vessels until he came under the side of the one nearest the shore. He caught at the hempen cable, swarmed up it, and, the gallivat having but little freeboard, soon reached the bulwark. There he paused to recover his breath and to listen. Hearing nothing, he quietly slipped over the side and lay on the maindeck. In a few seconds he was joined by his companion. In the shadow of the bulwarks the two groped their way cautiously along the deck. Presently Desmond, who was in front, struck his foot against some object invisible to him. There was a grunt beneath him. The two paused, Fuzl Khan nervously fingering the knife he had taken from the sentinel on the bastion. The grunt was repeated; but the intruders remained still as death, and with a sleepy grumble the man who had been disturbed turned over on his charpoy, placed transversely across the deck, and fell asleep.
All was quiet. Once more the two moved forward. They came to the ropes by which the vessel was lashed to the next in the line. For a moment Desmond stood irresolute; then he led the way swiftly and silently to the deck of the adjacent gallivat, crossed it without mishap, and so across the third. Fortunately both were sailors, accustomed to finding their way on ship-board in the night, as much by sense of touch as by sight. Being barefooted, only the sharpest ears, deliberately on the alert, could have detected them.
They had now reached the fourth of the line of vessels. It was by far the largest of the fleet, and for this reason Desmond had guessed that it would have been chosen for his quarters by the serang[#] in charge of the watch. If he could secure this man he felt that his hazardous enterprise would be half accomplished. This was indeed the pivot on which the whole scheme turned, for in no other way would it be possible to seize the ten men on board the gallivats without raising such an alarm as must shock fort, city, and harbour to instant activity. And it was necessary to Desmond's plan, not only to secure the serang, but to secure him alive.
[#] Head of a crew.
The gallivat was Angria's own vessel, used in his visits up-river to his country house, and, during calm weather, in occasional excursions to Suvarndrug and the other forts on the sea-coast. As Desmond was aware, it boasted a large state-cabin aft, and he thought it very probable that the serang had appropriated this for his watch below.
Pausing a moment as they reached the vessel to make sure that no one was stirring, Desmond and Fuzl Khan crept on to its deck and threw themselves down, again listening intently. From the last vessel of the line came the sound of low voices, accompanied at intervals by the click of the oblong bone dice with which the men were gambling. This was a boon, for when the Indian, a born gambler, is engaged in one of his games of chance, he is oblivious of all else around him. But on Angria's gallivat there was no sound. Rising to a crouching position, so that his form could not be seen if any of the gamblers chanced to look in his direction, Desmond slowly crept aft, halting at every few steps to listen. Still there was no sound. But all at once he caught sight of a faint glow ahead; what was it? For a few seconds he was puzzled. As he approached, the glow took shape; he saw that it was the entrance to the cabin, the sliding door being half open. Creeping to the darker side, careful not to come within the radius of the light, he stood erect, and again listened. From within came the snores of a sleeper. Now he felt sure that his guess had been correct, for none but the serang would dare to occupy the cabin, and even he would no doubt have cause to tremble if his presumption should come to the Pirate's ears.
Keeping his body as much in the shadow as possible, Desmond craned his head forward and peeped into the cabin. He could see little or nothing; the light came from a small oil lantern with its face turned to the wall. Made of some vegetable substance, the oil gave off a pungent smell. The lantern was no doubt carried by the serang in his rounds of inspection; probably he kept it within reach at night; he must be sleeping in the black shadow cast by it. To locate a sound is always difficult; but, as far as Desmond could judge, the snores came from the neighbourhood of the lantern and as from the floor.
