The line "pay off Ashby's score" refers to General Turner Ashby, Jackson's cavalry chief during his famous Valley campaign, who was killed by Union troops while fighting a rear-guard action near Harrisonburg, Virginia, June 6, 1862.
Popular legend has it that the original copy of "Stonewall Jackson's Way" was lost and
later found -- bloodied -- on the body of a sergeant in the Stonewall Brigade who was killed at Winchester, Virginia. The truth is that the piece was originally published in Baltimore, Md., as a clandestinely circulated broadside. In order to deflect the suspicion of the Union Provost Marshall's Office away from Palmer -- the true author -- the legend of the bloody paper was concocted. The ruse was successful enough to have obscured the true origin of "Stonewall Jackson's Way" for a more than a century.
