Dont forget, after Prairie Grove Battle, Union Troops came south. Confederates came right down off Log Town Hill in Van Buren Straight down Main Street (which is now a great shopping destination and Historic Value). Confederates mounted boats and headed to the Fort Smith side. 3 boats, two made it. They sunk one so it would not fall into Union hands. So if anyone has researched this out correct me if I am wrong. But my best guess if they headed straight across, it is now River Valley Motorcross park. Which is basically open land people pay to go ride whatever on. I can also picture Union cannons on the top of Log Town Hill using elevation to fire. And since the Artillery did not move as fast I am guessing it would put them there about the same time the boats were going over. So from the base of the Hill to the river then Straight across. But this last is just pure speculation on my part. But either way im up for a scouting here or hunt elsewhere.
