Was there transportation between the north and the south (U.S.) in the 19th century?
I have looked everywhere online and can't seem to find the answer to this question. I know there were trains, for example, in the north mainly but also in the south. However, was there transportation (even by sea) BETWEEN the two? Everyone knows that the north and the south were against each other then, but did citizens still travel to and from these areas, like to visit someone?
If someone has the answer, I would be more than grateful for you to tell me. Including the source where you found your information would be even more helpful.
Or maybe, does someone know where I can find the answer, myself?
