Picture a Civil War vintage camp. Big white tents. Cooks boiling everything up in giant iron kettles. Rations. Ammunition. Other stuff. I have the reference around someplace, but my recollection is that the typical Union INFANTRY regiment had a wagon train of several dozen vehicles. The soldier on the march carried his personal weapon and a small pack. The question of fretted or fretless banjo is important to some, but the SIZE of the instrument just isn't relevant...it would have been pitched into a wagon and retrieved later.
