"God save Ireland," Harper muttered.

"Is the gun loaded?" Sharpe slapped the carronade, then ducked as a stray musket bullet slapped over his head.

"Looks like it!"

Sharpe found another spike which he used to lever the gun's trail around so that the carronade faced straight down the Espiritu Sanyo's length to menace the quarterdeck, where Ardiles was assembling a group of seamen. Those seamen were undoubtedly intended to be the counterattack that would finish off Cochrane's assault. Sharpe hammered a quoin out from under the carronade's breech, thus raising the muzzle so that the dreadful weapon was pointing straight at the quarterdeck. The carronade was a pot of a gun, not a long, elegant and accurate cannon, but a squat cauldron to be charged with powder and metal scraps that flayed out like buckshot. A carronade's range was short, but inside that brief range it was foully lethal.

The whole ship quivered as another broadside slammed from the frigate's gun deck to shatter the heavy timbers of the whaler. Most of Cochrane's men were off the whaler now and crammed onto the Spaniard's deck where they were hemmed in by bloody pikes and bayonets. Ardiles, preparing his reserves to slam into the left flank of the invaders, was making things worse for Cochrane by destroying his only chance of escape by pounding the whaler into matchwood. Smoke was sifting from the open hold of the Mary Starbuck. Presumably some of the wadding from one of the Espiritu Santa's cannons had set fire to a splintered timber inside the attacking ship.

Harper cocked the flintlock that was soldered onto the carronade's touchhole. Naval guns did not use linstocks, for the spluttering sparks of an open match were too dangerous on board a wooden ship crammed with gunpowder. Instead, just like a musket, the gun was fired by a spring-tensioned flint that was released by a lanyard. "Are you ready?" Sharpe gripped the lanyard and scuttled to one side of the gun to escape its recoil.

"Get down!" Harper shouted. Ardiles's men on the quarterdeck had at last seen the threat of the forecastle carronade and a dozen muskets were leveled. Sharpe dropped just as the volley fired. The sound of a musket volley, so achingly familiar, crackled about the ship as the balls whipsawed overhead. Sharpe answered the volley by yanking the carronade's lanyard.

The world hammered apart in thunder, in an explosion so close and hot and violent that Sharpe thought he was surely dead as the frigate shivered and dust spurted out of the cracks between her deck planks. Sharpe's second and more realistic thought was that the barrel of the carronade had burst, but then he saw that the gun, recoiling on its huge carriage, was undamaged.

The explosion had been aboard the Mary Starbuck. A store of gunpowder in the whaler's hull had ripped itself apart in a moment's blinding horror, tearing her deck into shards and exploding the wounded into the sea. Now what remained of the whaler was ablaze. The dark red flames leaped voraciously from her oil-soaked planks to flare as high as the Espiritu Santo's topmasts.

"Mary, Mother of God," Harper said in awe, not at the incandescent whaler, but rather because the Espiritu Santos mainmast was toppling. The explosion had ripped out the frigate's chain-plates and now the great mast swayed. Some men, now recovering their wits after being stunned by the concussion of the explosion, shouted in warning, while others, from both sides of the fight, were desperately slashing at the remaining grapnels so that the roaring blaze on the whaler would not leap across to destroy the frigate. Beyond that chaos Sharpe could see a red horror on the poop- and quarterdecks where the blast of his carronade had taken a terrible toll among Ardiles's men.

A rebel officer shouted a piercing warning. The swaying mainmast splintered and cracked. Canvas billowed down onto the deck and into the sea. The collapsing mast dragged in its wake the fore topmast and a nightmarish tangle of yards, halyards, lines and sails.

"Come on, Patrick!" Sharpe cocked the pistol and jumped down from the forecastle. A Spanish sailor, groggy from the explosion, tried to stand in Sharpe's way so he thumped the man on the side of his head with the pistol's heavy barrel. A Spanish army officer lunged at Sharpe with a long, narrow sword. Sharpe turned, straightened his right arm and pulled the trigger. The officer seemed to be snatched backward with a halo of exploding blood about his face. Smoke from the burning whaler whirled thick and black and choking across the deck. Sharpe hurled the pistol away and snatched up a fallen cutlass. "Cochrane!" he shouted, "Cochrane!" A mass of Cochrane's men were swarming toward the frigate's stern. The explosion and the subsequent fall of the mast had torn the heart out of the frigate's defenders, though a stubborn rear guard, under an unwounded Ardiles, gathered for a last stand on the quarterdeck.

To Sharpe's left was a tall man with red hair who carried a long and heavy-bladed sword. "To me! To me!" The red-haired man was wearing a green naval coat with two gold epaulettes and was the man the rebels were looking to for orders and inspiration. The man had to be Lord Cochrane. Sharpe turned away as a swarm of Spanish fighters came streaming up from the gundeck below. These new attackers were the frigate's guncrews who, their target destroyed, had come to recapture their maindeck.

Sharpe fought hand to hand, without room to swing a blade, only to stab it forward in short, hard strokes. He was close enough to see the fear in the eyes of the men he killed, or to smell the garlic and tobacco on their breath. He knew some of the men, but he felt no compunction about killing them. He had declared his allegiance to Ardiles, and Ardiles could have no complaint that Sharpe had changed sides without warning. Nor could Sharpe complain if, this fight lost, he was hung from whatever yardarm was left of the Spanish frigate. Which made it important not to lose, but instead to beat the Spaniards back in blood and terror.

Harper climbed the fallen trunk of the mainmast. He carried a boarding pike that he swung in a huge and terrifying arc. One of the Irish crew members, having decided to change sides, was fighting alongside Harper. Both men were screaming in Gaelic, inviting their enemies to come and be killed. A musket crashed near Sharpe, who flinched aside from its flame. He ripped the cutlass blade up to throw back an enemy. The cutlass was a clumsy weapon, but sea fighting was hardly a fine art. It was more like a gutter brawl, and Sharpe had grown up with such fighting. He slipped, fell hard on his right knee, then clawed himself up to ram the blade forward again. Blood whipped across a fallen sail. A sailor trapped beneath a fallen yard shrieked as a wave surge shifted the timber balk across his crushed ribs. Balin, his face and hand still bandaged, lay dead in the portside scuppers which now ran with the blood from his crushed skull. A group of rebels had found room to use their pikes. They lunged forward, hooking men with the crooked blade on the pike's reverse, then pulling their victims out of the Espiritu Santa's ranks so that another pike-man, using the weapon's broad axe-head, could slash down hard. The pikemen were driving the frigate's guncrews back to the poopdeck where a rear guard waited with Ardiles and Lieutenant Otero.

The ship lurched on the swell, staggering Sharpe sideways. A bleeding man screamed and fell into the sea. It seemed that the Espiritu Santo must have taken on water for she did not come fully upright, but stayed listed to starboard. A volley of musket fire from Ardiles's group on the quarterdeck punched a hole in the rebels' ranks, but Cochrane, seeing the danger, had led a rampaging attack up to the poopdeck and now his men clawed and scrabbled up the last companionway to attack Ardiles and his men on the quarterdeck. Royalist Captain faced rebel Admiral. Their two swords clashed and scraped. More rebels were running past their leader, swarming up to the quarterdeck where a final, fanatic group of Spaniards, including most of the army officers, stood to protect their royal ensign.
