Still thinking about campaigns, and the role forts might play in them...

I was a bit surprised by the distribution of forts in the package: two big 9-burden ones, two still-quite-impressive 7-burden ones, and a single 3-burden battery if I'm not mistaken. How do these stack up compared to the kinds of forts one might find in, say, Mauritius or the West Indies?

Does anyone has any idea how many people would be required to man one of these forts? Counting the number of guns on the image, there aren't all that many. I'm thinking maybe the "formula" would be something like 5 * burden * crew boxes. So a 9-burden fort would have a 450 man garrison???

Anyone started playing around with harbor layouts? How might one simulate real-world conditions using the pieces we've received so far?
