Thanks, Scott. I found it enlightening as I researched it. Most accounts of the Chattanooga campaign skip over most of the time and trouble between Chickamauga and the opening of the "cracker line," but when looked at day-to-day (as is my practice) you see the troubles mounting while Rosecrans dithers and Bragg worries more about the enemies within his army than those without.
Also, I found it very interesting to see the day-to-day connections between what was happening around Chattanooga with the events in East Tennessee, and Sherman's problems in getting his troops into Chattanooga. I think I've shown that Burnside did about as well, in East Tennessee, as could have been expected of anyone -- that expectations of him rushing to Rosecrans' rescue after Chickamauga were extremely unrealistic, for instance.
Also, there were oft-recurring rumors, at the time, that Lee was sending even more troops to Georgia or possibly to East Tennessee via SW Va. These rumors (not true, of course, except that one brigade of Pickett's Div. was sent to SW Va.) played a major role in the maneuvering in East Tennessee, Grant's concerns at Chattanooga, and even in Lee's and Meade's maneuvering in northern Va.
