Gen, Pike wrote his After "Battle of Pea Ridge" Report on March 14, 1862 at Dwight Mission. Dwight Mission was/is located along Sallisaw Creek midway between Flint Court House (near Stilwell) and the mouth of Sallisaw Creek 35 miles southwest on the Arkansas River. See Pike's Report in OR Series 1, Vol. 8, pp. 286-292.
After the battle, Pike writes that he eventually withdrew some of his Indian Brigade back to Cincinnati, AR on the Cherokee line, probably around March 10. As there was only one convenient road from Cincinnati to Dwight Mission within two days march, the one passing thru Flint Court House and running southwest down Sallisaw Creek, this tends to confirm the point previously made in an earlier blog that Gen. Pike probably turned northeast toward Cincinnati near Flint Court House after receiving his new marching orders from MG Van Dorn, written at Strickler Station on March 3. The CSA Postal Route 373 ran along another road northwest from Flint Court House to Tahlequah.
You will recall that Pike's route from Flint Court House to Dwight Mission is the same route that MG Sterling Price retreated on in November 1864, and that MG S. R. Curtis Federal army pursued Price's army on two days later.
Dwight Mission seems to have been a special place, even during Civil War times, otherwise Gen. Pike would have never stopped there for a while and been able to compose such a long and thoughtful battle report.
