Jim:
BIG NEWS! The ship that launched DAUPHIN ISLAND'S 11TH ARMED AMPHIBIOUS INVASION is at the bottom of Blackwater Bay east of Pensacola or SOMEWHERE around there. It was intentionally stripped of armament and set on fire during the 1781 Siege of Pensacola. IT HAS NEVER BEEN FOUND! https://books.google.com/books?id=1JFT3OtBKGMC&pg=PA46&lpg=PA46&dq=%22hms+mentor%22+january+1781&source=bl&ots=7efVitsySm&sig=25e1n7IwRrN4ByKfnAH7wJ-8PVc&hl=en&sa=X&ved=0CDkQ6AEwBGoVChMIpOeshtLBxwIVghI-Ch2v2gsa#v=onepage&q=%22hms%20mentor%22%20january%201781&f=false
