For the Siege of Jackson battle you can use one corps of up to 20 units. 18 of your best infantry brigades plus one heavy artillery unit and a strong melee cav unit is a good mix.
Your task here is to defend a large, mostly fortified perimeter. Youโll get your first 15 units to start, then the rest later as reinforcements from the NE part of the map.
Pretty simple, really, if you know how to play this game. You have a big advantage as the defender of fortified positions—and as the opponent of a pretty dumb “AI.” You need only to avoid leaving big gaps, or thinly defended sections, that the Union can exploit.
You also, by this stage of the campaign, could have a significant advantage in numbers. Thus, once the Union forces are depleted by their costly attacks on your lines, you can—though it will be costly to you—extend your left or right flank (or both at once) and sweep the enemy from the field.

The same basic strategy works, and this battle is easier because CSA can bring 24 brigades. At least three should be big melee cav units.
