Attack on the Dutch flute

"Instead of sending that flute we'll be boarding today to the sea bottom, I could merely capture her, and give her to you, mon ami, to captain for me. Admittedly, she's a bit unwieldy and slow, but one must start somewhere. What say you, Jacques?"

- Christophe-Julien de Rapièr to Jack Sparrow

The Attack on the Dutch flute was an attack of the rogue pirates led by Christophe-Julien de Rapièr on a Dutch merchant ship in the Caribbean. The battle ended with slaughter of the entire Dutch crew.

Prelude to battle
"Jacques! Where have you been keeping yourself, mon ami? I've barely seen you since you joined us." "Orders, Captain?" "Ah, Jacques, that is not the way to be. We rogues saved your life, remember? If we had left you behind, you would have been the one that Captain Teague hanged at dawn."

- Christophe-Julien de Rapièr and Jack Sparrow

After Davy Jones identified Boris "Borya" Palachnik as the leader of the rogue pirates that violated the Code of the Pirate Brethren, the rogue Pirate Lord was imprisoned in a cell and sentenced by the Brethren Court to hang. Before his captors could torture him for more informations, he gave up the names of rogue pirate captains under his command. Christophe-Julien de Rapièr was one of them, and he was stopped before his ship could escape from Shipwreck Cove. Christophe's friend Jack Sparrow believed in Christophe's innocence, and he decided to help him.
