Not so sure about Montgomery myself. Charlotte was a railroad hub, large maintenance facility. The Catawba river ran close by town, must of had some foundries. I lived in Charlotte for a couple of years but noticed no remnants except for the railroad some of which was also at Spencer. Trains were (locomotives) stored in Charlotte to protect them from Sherman in 1864. I'm tracking the Army of Tennessee after the retreat from Tennessee in 1864/65. I've haven't made it to Montgomery quite yet. The path goes from Florence to Tupelo to Meridian to Selma to Demopolis to Montgomery to Macon, Milledgeville, Augusta, Columbia, Charlotte and Raleigh. Most of these were Confederate arsenals of one sort or another. I'm collecting data on as much of this path as possible, so I'm interested in all these locations. I found a good bit on Selma, Macon and Augusta so far, but not much on the others.
