Marcus Woodcock, A Southern Boy in Blue, ed. K. W. Noe (Knoxville: U. T. Press, 1996), p. 17 [written 1865, ref. to Ninth Kentucky Vol. Inf., autumn, 1861]:
        
        "A courier was immediately sent forward to order the Infantry to turn back [from an advance on Glasgow, Ky.] and we were soon returning to Tompkinsville. Captain Lankford proposed that we should have the band to play Boneparte’s Retreat and I believe it was played though I am not certain."

My guess is that "Bonaparte Crossing the Alps" or "Bonaparte Crossing the Rhine" was the tune he had in mind. (The Stepp-style "BR" probably wouldn't work with a brass band!)

Lankford must have had wry sense of humor.
