unusual preparation

Exploration Stage: Pier
From: Valerie
Description: I was just taking a stroll through the ship myself. Hey, there's a deep-sea mine on this ship, the kind you'd find in a military history museum! I didn't know they used them in the 19th century. Don't look at me like that, I didn't touch it. You don't believe me? See for yourself.
Completed: I hope this deep sea mine is no longer operational! Why would they need to sail this thing on a regular British frigate? Was he going to fight someone? Apparently the Colonel's mission was more military than diplomatic!
