"I challenge you to a duel. I win, you let me come with you. I lose, I leave and tell no one what I have seen here, or any of your plans." "Oh, Fitzy, I would love to. But, as it happens, I have yet to acquire the sword I really want. No sword, no duel. No boarding the ship for you. So sorry."
"Put it away, son. It's not worth you getting beat again." "You didn't beat me. You ignored the rules of engagement. In a fair fight, I'd kill you." "Then that's not much incentive for me to fight fair, then, is it?"
Duels in this form were chiefly practiced in Early Modern Europe, with precedents in the medieval code of chivalry among military officers. During the 17th and 18th centuries, and earlier, duels were mostly fought with swords (the rapier, the smallsword, and the French foil). Pistols were sometimes known to be used in duels as well. Although there were many who followed the fair ways of fighting in duels, there were those who fought dirty, mostly in their desire to win the duel or survive.
Jack Sparrow used John Brown's smithy as a hiding place to break his manacles after escaping CommodoreJames Norrington and his men of the Royal Navy. Will Turner arrived shortly afterwards and confronted Jack, who thought Will seemed "somewhat familiar". After Will realized that Jack was the pirate who had threatened Elizabeth Swann, a woman he cared deeply about, he engaged Sparrow in a duel.
Will would soon disarm Jack in their fight. However, through cheating, Jack would ultimately win the duel by pulling out his pistol, aiming it at Will. As Will blocked Jack's exit, Jack pleaded to Will to step aside, in which he refused. Even when he desperately didn't intend to do so, Jack prepared to shoot Will, so he could escape. But before he had the chance, Jack was knocked out by Mr. Brown and was captured by Norrington and his men.
Hector Barbossa and his crew arrived to Isla de Muerta with Will Turner to lift the curse of Cortés. Jack Sparrow interrupted the ritual and enter negotiations with Barbossa, which ends with Barbossa sending all but a few of his crewman to attack the HMS Dauntless and Jack stealing one of the cursed Aztec gold from the Chest of Cortés. Shortly after, the battle begins as Jack throws a sword to Will, who fights Barbossa's crewmen, while Jack dueled with Barbossa.----Will Turner would fight Jacoby, Clubba, and Monk alone through the battle. As he was about to be killed, Elizabeth Swann arrived to save Will and assist him in battle.
Elizabeth Swann helped Will in defeating Barbossa's crewmen as Jack threw his Aztec coin to Will. Barbossa prepared to shoot Elizabeth until Jack shot him in the heart with his last pistol shot. Will, having sliced the palm of his hand with the sacrificial knife and covering the coins with his blood, dropped both his and Jack's coins into the chest. With the coins returned and the blood repaid, the curse was lifted and Barbossa died.
"How'd this go all screwy?" "Well, each wants the chest for hisself, don't he? Mr. Norrington, I think, is trying to regain a bit of honor. Ol' Jack's looking to trade it, save his own skin. And Turner there, I think he's trying to settle some unresolved business twixt him and his twice-cursed pirate father."
The key was ultimately taken by Jack, who then unlocked the chest and stole the heart of Davy Jones. After he placed the heart into his jar of dirt, he was attacked by Koleniko, one of Jones' crewmen. Shortly after, a fight with many of the Jones' crew, which Elizabeth Swann, Pintel and Ragetti were in, continued onto the shallows of Isla Cruces. During the fight, Norrington finds the heart in the jar of dirt and escaped with it. The chest, along with its key, was taken aboard the Flying Dutchman to Davy Jones himself.
Jack soon got knocked down by Jones, who then confronted Elizabeth Swann and Will Turner. It was then that Jack was able to unlock the chest and planned to stab Jones' heart to achieve immortality. Jones then stabbed Will in the heart, after which Bootstrap Bill Turner attacks Jones. Jack then helps Will stab Jones' heart. Jones died and fell into the maelstrom. Shortly afterwards, Will became the new captain of Flying Dutchman.
In London, Jack Sparrow was being pursued by King George II's Royal Guards while leaping from moving carriages. After being saved by his father, Jack took refuge into the Captain's Daughter tavern, where he would confront an impostor who was impersonating him. As each Jack followed the exact movements of the other, the huge swordfight in the storeroom began.
Eventually, Jack would realize who the impostor was after the other Jack performed a familiar technique. He and other Jack clashed their swords before the two share a kiss—Jack's greeting to Angelica. Both Angelica and Jack have a brief reunion, until the King's Royal Guards break into the storeroom and fight against Jack and Angelica. The Guards aim their rifles at them. Jack and Angelica escape through a trapdoor and swam away, surfacing in the River Thames.
"Hang on a minute! I just—I just needed to understand something. Right. So, you will fight against them, they will fight against you, all on account of him wanting to kill him? Where's the sense? Exactly. I say, let them fight each other as we lay back, watch, have a drink, place some wagers! Eh?!"
With the help of Jack Sparrow, Blackbeard and his crew arrive to the Fountain of Youth for a chance of immortality. Barbossa arrived with his crew shortly after to confront Blackbeard for his crimes, particularly for the loss of his leg. Pulling out their swords, Barbossa and Blackbeard ordered their crews to attack. After Jack Sparrow briefly interrupted the fight, asking the sense of all crewmen to fight when the matter mostly concerned the captains, the battle ensued as Barbossa dueled with Blackbeard.----Scrum and Angelica would bring the Chalices and a mermaid's tear for the ritual of the Fountain. However, they would be interrupted by Jack Sparrow, who would want both items.
Blackbeard was soon able to trip Barbossa and prepared to strike him down, but not before the Spanish arrived to destroy the Fountain. After confronting the Spaniard, Blackbeard was run through by Barbossa with his sword, poisoned by the innards of poison dart frogs. Barbossa claimed Blackbeard's sword, along with his ship and crew, as payment for his missing leg. Blackbeard died immediately after performing the Profane Ritual, where he was tricked by Jack Sparrow.
Unlike many other pirate-themed movies in which all naval and pirate officers dueled with rapiers and used thrusting strikes only, the Pirates of the Caribbean movies gave a realistic depiction of pirate weapons and sword-fighting techniques.
