Somebody asked about the vulnerability of supply lines. As things stand on October 2, both forces have armies positioned deep within enemy territory. Take a look:
The road networks in eastern Tennessee are pretty good. Lots of options are available for the supply masters. That said, Rogers' Army could be in big trouble if the Army of the East cuts north and re-takes Chuckville. Luckily for them, General Brock has orders to pursue them north and force a confrontation before Commander Hurst invests his forces in a siege of Tazewell.
On the other side of the ledger, the Harlan Blitz can trace an unbroken line of supply up through Big Stone Gap, down through the Cumberland Gap, and hence to Knoxville. That will change if Tazewell falls - an event which would put both the Blitz and Army of the Pines out of supply. The Blitz is small enough we may allow them to live off the land, but such rapacious practices won't last long. If they are forced into that, they run the risk of rebellion in Duffield and Big Stone Gap. That would force them to either head back east or fully commit to attacking the high walls of Kingsport.
