I am starting as the CSA in the 1864 scenario playing against the vanilla AI. I am not an expert player, but I have read some good advice on this board. The AI is set to hard with extra bonuses and more time; historical attrition for me only.
My premise is that, out of desperation, the CSA gives unprecedented authority to the executive (player), while in the US, a concerned congress has begun interfering with high command decisions (AI). Will the (hopefully) superior command of the CSA be enough to force a stalemate?
Strategic Assessment
Military: The army is hard pressed and poorly equipped. Artillery is especially needed. Divisions are understrength and many are poorly placed, especially those stranded west of the Mississippi. We are heavily invested in cavalry. (I thought the south was short of mounts late in the war.) This gives us some counter-attacking potential, but is less useful for the essential task of defending cities from larger armies. The navy is virtually gone.
Economy: Many of our greatest cities have been captured. Inflation stands at 40%. Our blockade running operations have withered to almost nothing. By heaping misery on the populace, we can raise money and recruits, but without access to European markets, we are severely limited in war supplies.
Politics: Here is sole Confederate hope. The CSA merely needs to stave off defeat, while the US requires victory.
Meta: I will be interested to see how Athena does on the offensive with such superior forces. In particular I think it's "deep raids" make more sense and will be harder to counter because I have fewer resources to challenge them and because they have more places to seek refuge. If nothing else, it can afford the losses easier.
