So the Yankee invading hordes are besieging Island No. 10, with a strong naval force in the river. I send my local naval force upstream, expecting it to bolster the defense of the island and keep supplies flowing. They go into the Reelfoot Lake (?) river area where the Yankees are already present. I put them on defensive strategy, conservative stance. A battle ensues, in which the fort's guns don't seem to be participating, and at the end of the battle, which lasts one round, my ships retreat _upstream_, to the river area between Cairo IL and Missouri, seemingly bypassing both the USA navy and the fort guns at Cairo. Anybody understand how this happened?
Also, why did neither fort's guns (Is. no 10 or Cairo) attack?
