Navy, with a top speed of 6 knots, could not navigate upstream on the
Mississippi River during the Civil War. I have trouble accepting
this because of reports that these vessels moved back and forth from
Memphis to just above Vicksburg.
However, I suppose it's possible the Union Navy could have been
towing these vessels back upstream.
