Welcome to RevWarTalk, thanks for visiting.
That is exciting you are writing a piece set in the period. I will be honest in that I am not deeply familiar with some of the southern battle histories and landscapes. Being from the northeast I am closer in proximity and knowledge of the areas around Philadelphia and New Jersey. I do love learning though so read up some more on the Battle of Blackstock’s. You likely have seen this website (link below), though it shares a relatively detailed account of the day and while the author notes merely “a ford upon the Enoree”, maybe other context clues might help pin down which ford it was. The link is: http://www.carolana.com/SC/Revolution/revolution_battle_of_blackstocks.html
Can you share more about the plot of your tale or is it still in develoment?
