The admiral nods.
Good. Jack, would you like to lead the land force against the fort? The fleet cannot attack until the fort is secured-otherwise we are going to be blasted by shore batteries while fighting. If you can take the fort, you can then have that witch bring you back to the fleet and then help in the naval battle as well. That will let our fleet know when the fort is secured without needing to do anything that would alert the enemy fleet like sending a signal.
