Sparrow: The ship is ours!
Blackbeard: Gentlemen, I be placed in a bewilderment. There I were, resting. And upon a sudden, I hear an ungodly row on deck. What be that, first mate?
Angelica Teach: Mutiny, Captain.
Blackbeard: And what fate befalls mutineers? Now, we know the answer to that, do we not? Mutineers hang!
Sparrow: Captain, I wish to report a mutiny.
“I be placed in a bewilderment”; “There I were”; “upon a sudden”; “What be that” = These phrases are in old-English, or at least what we think might be the way pirates would have talked a long time ago.
The same lines in modern English might sound like, “I’m bewildered. There I was, resting, when all of a sudden I heard an ungodly row on deck. What is it, first mate?”
to be bewildered = confused
a row = a fight, a commotion
a mutiny = when the crew of a ship takes control from the Captain
a mutineer = A person involved in a mutiny.
