The lead archeologist is saying some strange things.
He talks about ordinary chain shot as if it was a unique improvised weapon that only this pirate used. Well chain/bar shot was in common use by navies to take down rigging.
It’s not to “terrorize” an enemy, its to win by crippling the opponent ability to manuever.
And langrage is just a slight change to cannister/grape shot, something also widely used by navies and not unique to pirate.
So they found ball, grape and chain shot, just like you would find on any warship of the time.
That lead archeologist needs to watch some old Errol Flynn movies.
Kick these ``archaeologists`` off the poop deck!
