That, I did not know at all. I'm kinda blushing to admit that I only knew about the Constitution being on the rolls because it was a plot point in one of the episodes of the G.I. Joe cartoon in the Eighties. IIRC, the Constitution sank a full-sized Navy battleship whose captain had defected to Cobra.

Yeah you read that right. A sailing ship destroys a steel-hulled battleship.

YO JOE!!!

It is even worse (Or better) in the Royal Navy.

The only ship in their fleet that has sunk or even engaged an enemy is the HMS Victory which was laid down in 1759 and last fought an action in 1805 at the battle of Trafalgar. .
