Some points---
I did some studies about invading forces vs entrenched defending forces. The invading force was about 3 times larger than the defending which had just a little more than 1/3 the artillery that the invading force had.
The quintessence was that the artillery was devastating; as long as enough defending infantry was alive to protect the artillery and the force did not break and run --were set to hold-at-all-costs--, the artillery pounded the invaders horribly. Some times the invading force, about 2 divisions vs a small defending division with an extra 12lber, was destroyed down to just the artillery, of which about 1/3 - 2/3 hits had been scored. Occasionally, even though the defenders were on hold-at-all-costs, the commander lost his nerve and retreated. In nearly no case was the invading force in any condition to do anything other than lick their wounds and try to recover.
If this were vs a region with a fort the invaders might besiege the fort, but
[INDENT]they would take a long time of recovery before they were strong enough to attack it, depending on the exact situation
getting supplies could be a major issue
they would be very vulnerable to counter-attack.
[/INDENT]
So always keep a small garrison in your forts, and if you are serious about defending them against invasion you will need a well entrenched force of nearly division size with some extra artillery.

Norfolk is adjacent to James Estuary, Hampton Roads and the Atlantic Coast region to the east; it's the region, not the town that counts. So units sailing from Hampton Roads to James Estuary can be bombarded by units in the Norfolk region.
The problem with Norfolk is that with a few ironclads it is not that difficult to blockade it and you can invade directly if the defender is only inside the town or even if it is you can attack it from the south --historical approach-- and starve the defenders out if they try to hold out. A fort will be of little use in this case.

Forts in and of themselves don't block supplies, artillery that can bombard does.

If you can draw any open path on the map with your finger from your unit to a supply source, even around forts and enemy forces, you will probably get supply. If you are planning to block supply, the converse is the case.

Owning Paducah with a fort and good artillery will break the Mississippi in two and cut the Ohio off in the process. This will be a major PITA for the Union for many reasons.
If you do this DO NOT think that the Union cannot "walk" across the Mississippi from Scott, Missouri and attack Paducah. Your fort in Paducah with all the artillery in the world will not even raise an eyebrow on a force "marching" across the Mississippi or the Ohio. You must defend from the banks of the rivers.
