I examined this juncture on the Ala & Miss RR some years ago in conjunction with a report of the movement of prisoners of war from Croxton's brigade captured at Trion, April 1, 1865 (in "Loss of the Sultana," Chester Berry, 1892). He (Private Thrasher, Co G, Sixth Kentucky Cav) stated that after they were imprisoned at Marion, ". . . From Uniontown we went to Moberly, Ala., on Tombigbee River. There we stopped for the night. . . On the following morning we boarded a boat, crossed the river . . . Then we started from there to Meridian, Miss. . ." I realize now that I had assumed that they had been transported by rail, Marion, Uniontown, and Meridian being on the road. However, Thrasher nowhere suggests his riding a Confederate rail car, which in 1865 should have been a memorable experience. In fact, the only means of travel he mentions is marching. I still do not know where "Moberly" on the Tombigbee River might be.
As I recall, this crossing of the Tombigbee by this rail line remained a ferry into the late nineteenth century, albeit a bit more sophisticated operation than in the days of Confederate Alabama. When I jar the right side of my head with the heel of my hand, I can recall an image of this ferry in a reference you sent me.
