 In May 1862, Morgan's riders captured two Union trains at Cave City, but his apparent goal was to agitate Union forces; he paroled everyone aboard, returned one of the trains, and sent the occupants back to Louisville.This move accomplished little except to embolden Morgan for a more extensive raid in July.On July 4, 1862, Morgan and his men left Knoxville, Tennessee and captured Tompkinsville five days later.
