In 1863, at least, Charleston had 385 guns in their land forts. May be part of why the city was never taken by sea. Sherman eventually took it from the land side.
Rather nuts to send warships at it, isn't it? How odd that they never completed their mission because Lincoln had absentmindedly sent the command ship to Florida disguised as a British fishing ship or something.
I don't know why the Confederates thought they were going to be attacked. They must have been jumpy or something. They should have realized that those ships were never going to attack them, despite what their orders said.
Couldn't they tell that Lincoln was only joking?
