Any of Forrest's biographers will discuss Forrest's escort at different times in their books. John Allan Wyeth's That Devil Forrest: Life of General Nathan Bedford Forrest mentions the escort company repeatedly. It's a Google Book, so you can search the text for the word 'escort' and find every reference.

Here's a publisher's reference to this book. There are several other great books on this Confederate leader.
