Col Peters,
I don't know why the reb A units are routing at Vicksburg, doesn't make sense as an A class unit should not rout unless it has some kind of debit to it's Morale Value, it's starting Morale is 6 and that is the highest number you can roll and according to the User Manual the Morale Die Roll has to exceed the units Morale Value to rout a unit. They get debits to their Morale Value for being D'd, out of ammo, medium/high FA, enfilade fire. If you think there's a problem maybe you should contact HPS Support.
Gen Lynn,
I believe your understanding of the Command Rules is not correct, at least according to the User Manual
"At the beginning of each player’s Turn, a Command Test is performed for <u>all leaders</u> currently on the map. The Command Test begins with the highest commanding leaders on the map and proceeds downward through the command hierarchy."
So Walker makes a command check regardless of whether or not his commander is on the map. With a command rating of B he passes on anything but a 6 so he should be in command most of the time. Once again from the User Manual
"A Leader which passes his Command Test will pass a +1 Command Bonus modifier down to the Command ratings of his subordinate commanders (except to Detached Leaders)."
this would mean Walker would pass on a +1 bonus to his brigade commanders when they make their command check if they are within command radius of him.
Even if Walker fails his command check his brigade commanders will still make their command check and could still pass a bonus on to their units if they pass.
Finally the command status of a brigade officer will only affect his units ability to recover from being D'd, it has nothing to do with morale other than the -1 modifier to a unit's morale for being D'd.
