Hugh, great information. You have enlightened me on Camp Townsend and now the late war exchanges. I found exchanges of my Louisiana boys in November 1862 at Vicksburg and then from there it was City Point and Boulwares and Cox's Wharfs.
Went on railroads from Midwest to Philly and Baltimore? Picked up at Baltimore and then to Virginia? Ever found newspaper articles in Baltimore talking about this kind of stuff Hugh?
Btw, thanks for the awesome email you sent me!
