Seamen were running to haul on ropes; gradually the lower corners of the great maintopsail, the clews, were pulled up and in towards the middle, a quick way of reducing the area of the canvas and the Calypso's speed.
Suddenly there was an enormous drumroll, turning into a reverberating explosion inside the harbour which hurt the eardrums and echoed and re-echoed among the hills, punctuated by the shrill screams of startled gulls, and, a moment later, while the noise was still rolling and rumbling like thunder, Ramage saw a great cloud of oily smoke streaming up from the middle of the harbour, as though from an enormous bonfire.
A few moments later the Calypso had sailed far enough for him to be able to see into the entrance. The southernmost frigate had blown up: one of the shells must have landed in her magazine. All that could be seen of her were her masts poking out of the smoke: some spars had toppled over across the next frigate, festooning her with rigging, yards sticking out at crazy angles like pins in a pincushion and several with sails still attached and beginning to burn. The weight of the wreckage was making the centre frigate heel to the south, over the spot where as the smoke drifted the hulk of the exploded frigate could now be seen amid a white froth of water. All over the harbour there were splashes, like leaping fish: it was raining wreckage ...
A ball of smoke appeared above the hulk as another mortar shell burst in midair; a second one landed close in the water and exploded a moment later, stirring up the wreckage. A third landed well beyond, over the quay, and then a fourth burst high in the air, the fuse obviously cut too short. Then Ramage spotted a movement: the northernmost frigate was making a desperate attempt to get out of the harbour: obviously all the lines holding her stern to the quay had been cut and she was being pulled forward by the weight of her own anchor cables; being pulled clear of her consort, which was likely to catch fire at any moment from the wreckage of the third ship.
At this moment the Calypso was in a perfect position, but every passing minute carried her southwards across the harbour entrance, so that she would have to tack back and then wear round again . . .
"We'll heave-to, Mr Aitken," Ramage said. "Trice up the port lids and run out the guns. Warn boarders to stand by and -" he glanced round, looking for Renwick "- I want the Marines ready, first as sharpshooters and then perhaps as boarders."
The Calypso began swinging again, to head into the wind as she hove-to, turning back towards the Feniglia and then lying stopped in the water like a resting gull as backed foretopsail pressed the bow to starboard and mizentopsail pushed it to larboard, so the two forces balanced.
Ramage continued watching the French frigate. His telescope revealed men now swarming up the rigging and out on to the yards. On the fo'c'sle men were struggling to load the two bowchase guns. The drooping curve made by the anchor cables was shortening as the weight of the heavy ropes sinking into the water pulled the ship forward and towards the harbour entrance. Ramage expected to see them vanish the moment the two cables were hanging down vertically from the hawsepipes, cut on board and freeing the ship.
So far the northerly breeze had not begun to push her over to the southern side of the entrance, to the rocks at the foot of the headland forming La Rocca. If her captain had remembered to put the wheel over to make use of the little way the ship had from the drag of the anchor cables, he might manage to keep her over to larboard long enough to get a sail set. Any squaresail would help; the foretopmen, for instance, should be streaming out on the yard slashing with knives at the gaskets which kept the sail furled.
Then he caught sight of frantic movement on the frigate's starboard quarter: she appeared to be towing something - it was the raft which he had seen between her and the next frigate; the French had been using it as a ramp to load the horses and guns. Now they were trying to cut it free - and there was a gun carriage perched on it, like a cat adrift on a box.
The foretopsail dropped like a huge napkin being shaken, there was a pause as the yard was hoisted, and almost at once Ramage saw the movement as the yard was braced sharp up and the sail sheeted home. The main course was then let fall and sheeted home - and a splash at the bow showed that the anchor cables had been cut, snaking out of the hawseholes and splashing down into the water.
As the main course was trimmed, so the fore course was let fall, and by now the French frigate was getting clear of the harbour entrance. How far did those rocks run northward from La Rocca? Ramage watched tensely, conscious of a slight tremble as he held the glass. The frigate came on; there was no shudder, so she had not bumped a rock. She had plenty of way on now, and as he watched the masts he realized she was managing to turn slightly to larboard, away from the rocks and more into the centre of the channel out of the harbour.
With topsails and courses set she would move fast the moment she was clear of the harbour and able to bear away to the south. It was time for the Calypso to get under way again, wearing round and running down to meet her.
He gave a stream of orders to Aitken, who began bellowing through the speaking trumpet. Southwick had produced his great sword from somewhere and was buckling it on: Silkin, his steward, was offering him pistols and a cutlass and belt. Ramage took the pistols as Silkin assured him they had been carefully loaded, and took off his hat for a moment as the steward slipped the cutlass belt over his head and settled it across one shoulder. He tucked the pistols into the band of his breeches, after assuring himself they were at half cock, thanked Silkin and watched as the Calypso, foretopsail now drawing, wore round to head down towards the two anchored bomb ketches. The maintopsail was drawing again - Aitken did not have to be told that one did not chase after escaping French frigates with the maintopsail still clewed up.
A shout from Aitken and there was a heavy rumble across the decks as the starboard side guns were run out; then, after a pause as the guns' crews ran across to the other side of the ship and took up the side tackles, another rumble as the larboard guns were hauled out so that their muzzles stuck out through the ports, stubby black fingers.
Closer to him there was a grating noise and a series of thuds as the carronades were run out on their slides. Thirty-six 12-pounder guns, eighteen a side, and six carronades, three a side ... all loaded and ready.
A pillar of water spurted up vertically just astern of the French frigate, and smoke was mixed in the shower of water droplets: one of the mortar shells had just missed and burst in her wake: extraordinary that the fuse should continue burning under water. The Board of Ordnance always claimed that they would, but he was never quite sure what sort of tests the soldiers were likely to make to prove the point. What an explosion it had made . . .
An orange flash turned into oily brown smoke just ahead of the French frigate, and Ramage realized that his lads in the bomb ketches were shooting with quite fantastic skill; they needed just a little more practice at firing at a moving target. . . A little more, he thought ruefully; they had never fired a mortar at a moving target in their lives, and he doubted if there were any officers serving in the Navy who had.
Now the Calypso was beginning to move fast through the water with the wind on her starboard quarter; the French frigate was quite clear of the harbour and for the moment appeared to be heading straight for the two bomb ketches, as though determined to sink them in revenge. On the other hand she might be trying to make sure she had enough offing to run clear without getting close to Isolotto. French charts might not be very accurate.
An isosceles triangle, he thought: that's what we make. The Frenchman is one corner, the bomb ketches another, and the Calypso at the top, on a course which should cut the triangle in half. Bisect it, he corrected himself, and found he wanted to giggle.
