Played as the CSA for some time and started thinking in terms of fortifying the bottlenecks like Fredricksburg, Cinncinati and St Louis. The idea is to create an obstacle which 'fixes' the Union armies at one point so that I can hit them with my concentrated forces. Yet it doesn't seem to work...
Union armies bypass my fort at Manassas with impunity, rarely stopping there to beseige the fort there. At Fredricksburg they arrive and assault it immediately. Very often them manage to take it really quickly even with a collection of ex-militiamen turned regulars (about 12 units).
So, what exactly are the uses for (buildable) forts on the map? Do they impede/slow the progress of an opponent? Or do they just enhance the defence of one particular location? If so by how much?
Tnx in advance!
