We had family at the Battle of Cowpens and at the Battle of King’s Mountain.
It is a National Park Service Historic Trail with a printed guide describing places and events followed by the Overmountain Men in 1780. There is a small visitors center in Abington and a very good museum at Sycamore Shoals State park plus fort Wataugs. The trail goes to the National Battlefield at Cowpens where the Overmountain men readied for the battle at Kings Mountain. There is an NPS National Battlefield at Kings mountain.
It is a great trip through the back roads of East Tennessee and Western North Carolina.
There is a very good NPS staffer at Kings mountain who researched all the various Revolutionary battles. Surprisingly, there are far more in SC than any other colony with New Jersy coming in second.
