Poignant Civil War-era soldier's letter, dated September 30, 1862, was written by Andrew L. McFarlane of Knapp's Pennsylvania Artillery (Independent Battery E, Pennsylvania Light Artillery). In the letter, the soldier details his plans to return home by passing through the recently bloodied battlefield of Sharpsburg, Maryland (Antietam), offering a powerful first hand perspective in the immediate wake of the battle. The document is accompanied by its original hand-addressed envelope and measures approximately 8 in. H x 10 1/8 in. W overall, with condition disclosures including paper bends, edge wear, age toning, and overall wear consistent with antique military correspondence, Civil War letters, and collectible historical ephemera.
