Although many books on Gettysburg have addressed the role played by Brig. Gen. John Buford and his First Cavalry Division troops, there is not a single book-length study devoted entirely to the critical delaying actions waged by Buford and his dismounted troopers and his horse artillerists on the morning of July 1, 1863. Award-winning Civil War historian Eric J. Wittenberg rectifies this glaring oversight with "The Devil's to Pay": John Buford at Gettysburg. A History and Walking Tour.

This comprehensive tactical study examines the role Buford and his horse soldiers played from June 29 through July 2, 1863, including the important actions that saved the shattered remnants of the First and Eleventh Corps. Wittenberg relies upon scores of rare primary sources, including many that have never before been used, to paint a detailed picture of the critical role the quiet and modest cavalryman known to his men as "Honest John" or "Old Steadfast" played at Gettysburg.
