He helped form the KKK after the war, but called for it’s dissolution in 1869. By 1875 it was dissolved, and he had clearly changed his beliefs.

This was written by one of his soldiers after the Fort Pillow massacre:
“The slaughter was awful. Words cannot describe the scene. The poor, deluded, negroes would run up to our men, fall upon their knees, and with uplifted hands scream for mercy but they were ordered to their feet and then shot down. I, with several others, tried to stop the butchery, and at one time had partially succeeded, but General Forrest ordered them shot down like dogs and the carnage continued. Finally our men became sick of blood and the firing ceased”
