It helps. I used to have a good source on things in my good friend the late Jeff Weaver, an historian extraordinaire. Sadly Jeff passed away 3 years ago. He and I had ancestors who served with the Army of Tennessee in the 63rd Virginia Infantry. The Army of Tennessee has been neglected by historians who seem oblivious to the fact that the AoT had the herculean task of being on the move and campaigning over a region half the size of Europe while Lee's Army of Northern Virginia was bottled up at Petersburg for 9 months.
