How should the Union player move from Memphis to Vicksburg? I fear that floating down the Mississippi and landing amphibiously will put me out of reach of my supply network, which has a maximum range of five regions, as I recall. There aren't any CSA forts or fleets in my path, as near as I can tell, but the banks of the Mississippi are "red supply" on both sides. Can I use the river as a supply line in this circumstance, or should I focus on a closer target first? Or do I have to march down one or both sides of the river before surfing down it?
Alternatively, will it work to supply a beachhead in Vicksburg from New Orleans, if I invade that amphibiously (by sea, not river) first?
Many thanks in advance! I'm having a blast with this game.
