CHAPTER XIII

The Taking of Fort Aguila

During the morning, while the ladder was being made, Dennis had talked over with the sailors the plan of action he proposed to adopt should they succeed in entering the fort undetected. The first thing was to silence the sentry, if sentry there was. It was quite clear, from the fact of having been undisturbed hitherto, that no careful look-out was kept; but Dennis did not forget Copstone's suggestion that a sentry might be napping behind the parapet, and it must be his first business to assure himself on this point before giving the signal for his companions to make the ascent.

He crouched motionless in the embrasure, listening. It had been pierced for only a short gun—a minion or falconet perhaps; and doubtless within three feet of him was a stone walk extending for the whole length of the wall. All was still; there was not a sound to show that, within the enclosure, a hundred human beings were crowded, masters and slaves. But looking through the embrasure Dennis saw a few lights twinkling in the centre of the fort, and he guessed that some at least of the enemy were awake. However great their security, it had seemed incredible to him that the place should be left wholly unguarded, even if only to provide against turbulence on the part of the slaves.

After a few moments Dennis ventured to crawl towards the inner end of the embrasure, where he might get a view of the whole enclosure. The thin light of the moon fell on the brightly painted walls of the commandant's house in the centre; there was no light in the windows; no doubt the señor capitan was fast asleep. But a beam of light came from a building somewhat to the right; this was presumably the officers' quarters. The huts along the western wall, in which the slaves slept, were all in darkness. On the farther side of the enclosure, in the round tower beneath which the prisoners were confined, another light shone forth; somebody was awake there. But not a sound stirred the heavy moist air of the tropical night. If there were sentries upon the walls, they were certainly not pacing up and down.

Waiting another minute or two, Dennis ventured to peep round the corner of the embrasure. He could scan the whole length of the walk from tower to tower; no sentry was in sight, but he saw the gun below him a little to his right. Taking courage from the silence, he slipped out of the hole, and groped his way on bare feet toward the tower at the north-east angle. Every now and again he paused to listen, and at last, when he came within a few yards of the tower, he heard a sound of deep regular breathing hard by. Evidently some one was asleep. He stole along by the parapet in the deep shadow cast by the moon, until he saw, huddled in the corner between the tower and the wall, the form of a man. He halted to consider. Should he go forward and pounce on the sentry, risking the sound of a struggle if he attempted to gag him, or a cry if he struck at him with his sword and failed to kill him outright? It went against the grain to slay a sleeping man, and the sentry was apparently so fast asleep that it seemed possible for the rest of the party to climb up without disturbing him.

But there might be a sentry at the other end. Leaving the man in peace, Dennis stole back again, went on hands and knees where the gun necessitated his coming for a moment into the moonlight, then rose and groped his way along beneath the parapet as before. There was no sentinel, asleep or awake, in this direction. With more confidence now in the chances of a safe ascent he returned once more to the embrasure, and, taking from his pocket a thin piece of creeper, he paid this out through the aperture. He soon felt a slight tug from below. He waited until he felt a second tug, then gently pulled the creeper towards him. To the end of it a stout line was attached—a part of his salvage from the wreck of the Maid Marian. This he quickly secured to the heavy gun, and having strained on the rope to convince himself that the fastening would hold, he gave the signal by another tug to his comrades below.

Then he crawled into the embrasure, and, leaning out, saw Amos swarming with a seaman's nimbleness up the rope. Giving him a hand when he came within reach, Dennis helped to haul him into the embrasure.

"What about the calivers?" he whispered, for the sailor had come up unarmed, lest a clank of steel against the wall should attract attention.
