Stowed atop the chain were several implements—notably a matched pair of short axe-like tools, packed in oakum to keep them from clanking about “and waking the ducks,” as van Hoek liked to phrase it. Jack removed these one by one and hung them about his shoulders on their braided cotton straps. When the only thing remaining in the tun was the chain, Jack tipped it so that the water of the Guadalquivir spilled in over its top. Within a few moments the weight of the chain had driven it down below the surface. Immediately the line he’d lashed round the anchor cable began to take that weight. It tightened, but his knotwork held fast and it did not slip down.
What he feared most, now, was a long wait. But he and Dappa had used up more time than the Plan called for, or else the galleot had moved too hastily, for almost immediately they began to hear shouting from upstream: several voices, mostly in Turkish but a few in Sabir (so that the Spaniards on the brig would overhear, and understand), shouting: “We are adrift!” “Wake up!” “We’re dragging the anchor!” “Get the oarsmen to their stations!”
The watch on the brig heard it, too, and responded smartly by clanging a bell and hollering in nautical Spanish. Jack drew a deep breath and dove. Pulling himself hand-under-hand down the anchor cable, he descended until his ears hurt intolerably, which he knew would be a couple of fathoms deep—deeper than the draft of the onrushing galleot, anyway—and then began assaulting the cable with the edge of a dagger. He was working blind now, feeling one greased hand slide over another—a trick he’d worked out to prevent accidentally severing a finger. The blade made an avid seething noise as it severed the cable’s innumerable fibers one by one and thousands by thousands.
One of the cable’s three fat strands burst under his blade and unscrewed itself—he felt it slacken under his cheek, for he was gripping the cable between his head and shoulder, and felt the other two strands stretch and bleat as they took the load. He had no idea what might be going on twelve feet above. The galleot must be approaching, but it made no appreciable noise. Then there was a stifled thump, felt more than heard. He flinched, thinking it was the sound of the collision, and bubbles erupted from his nostrils. His eyes were still closed in the black water, and he was seeing phantasms: poor Dick Shaftoe being pulled up out of the Thames ankle-first. Was this how Dick’s last moments had been? But such thoughts had to be banished. Instead he conjured up van Hoek on the roof of the banyolar weeks ago, saying: “When we are some ten fathoms away from the brig I’ll strike the big drum once—just before we collide, twice. You’ll hear this, and with any luck so will the Vagabonds ashore, so they can make more noise for a few moments—”
Jack sawed viciously at the cable and felt the yarns of the second strand spraying outwards like rays from the sun. He sensed the hull of the galleot over his head all of a sudden and felt real panic knowing it stretched, an impenetrable bulwark, between him and air. At once came two thuds of the drum. He hacked at the cable’s one remaining strand and finally felt it explode in his hand like a bursting musket, the crack swallowed up in an incomparably vaster sound: a grinding drawn-out crunch like giants biting down on trees. The cut end of the cable snapped upwards and lashed him across the shoulder. But it did not whip round his neck, as had happened in many nightmares of recent months.
Something hard and smooth was pushing against the skin of Jack’s back—the hull-planks of the galleot! He could not tell up from down. But those clinkers were lapped one over the next like shingles, and by reading their edges with one hand he knew instantly which way was down towards the keel, and which was up towards the waterline. Swimming, fighting his own buoyancy that wanted to stick him against the hull, he finally broke the surface and whooped in air, baying like a hound.
Above he heard shouting and panic, but no gunfire. That was good, it meant that the brig’s officers had recognized them as the feckless rug-merchants seen earlier today, and not jumped to the conclusion that they were under attack. The Corsairs had lit lanterns up and down the length of the galleot shortly before the collision, so that Spaniards running up from belowdecks, rubbing sleep out of their eyes, would be presented with the reassuring sight of oarsmen who were still safely in chains, and free crew members who were unarmed and disorganized.
