Yeah!! the Jimmy would be ....no more..
They had one of these then a 8 inch then another and so on all around the perimeter of the fort. AND.. on three levels!!
they could bring 1100 guns to bear on a target... but by the time they finished, the rifled barrel came about and the pirates could shoot two hundred yards further!!
never a shot was fired! but it was Dr. Mudds home for several years.
must have been fun schleping all those cannons from the foundry's up north all the way to 75 miles from key west on a sail ship then hump them up 3 floors!!
