1) I have Bonham commanding a Corp. I order him to retake Norfolk. He performs poorly and his Corp retreats into North Carolina. I look around for another 2* and find that Gustavus Smith might do a better job so I send him by rail to meet Bonhams Corp in Garys, NC where I intend For Smith to releive Bonham as corp commander who will be sent back to Richmond for a desk job

. When this rendevous takes place I break up the Corp and pull Bonham out with orders to go to Richmond. That leaves me with Smith's command, consisting of only Smith, and Longstreet's command, consisting of the remaining 3 Divisions of Bonhams old Corp (Longstreet being the most senior), some Corp artillery and a Supply Wagon. Smith is the only 2* in the region and I can't get the "form Corp" button to activate. I have even tried to converge Smith into Longstreets command and it still doesn't work. What have I done incorrectly?
2) I have asked this before and never got an answer. On the roster page filtered for Commanders, there is an item titled "HEALTH" with a value. It's driving me crazy to find out what this value stands for. I might be a number such as "18" or "257 " or sometines it is a fraction stated as "1/1" or "8/20" for example. The tool tip says "Health/Hits but what does a single number like 35 mean? Also what signifigance does Health have in the commanders performance in the game.
I hope someone answers. Thanks in advance.
