The author, John Singleton Mosby, also known by ‘the Gray Ghost,’ was a Confederate army cavalry commander in the American Civil War. This is his account of the cavalry battles in the Gettysburg campaign in general ― and in particular, it is a vindication of the charge of J.E.B. Stuart’s tardiness at the Battle of Gettysburg, thus being a contributing factor to the Confederate loss of the battle. Mosby, in defense of Stuart, contends that the orders given to Stuart a week before were to ride around the rear of the Union army moving northeast and to ultimately intersect with Gen. Ewell near York, Pennsylvania. Mosby writes with piercing, acerbic humor. For instance, in his reply to Henry Heth’s statement, “The failure to crush the Federal army in Pennsylvania ... can be expressed in five words — the absence of the cavalry…” Mosby retorts, “I would rather say it was due to the presence of Heth.” Included also is a rebuttal of some of Mosby’s claims by Thomas Mann Randolph Talcott, Major and Aide-de-Camp General Robert E. Lee, 1862 and 1863. An interesting discussion of the cavalry at the Battle of Gettysburg.
