Relating a variety of rarely told stories, this overview explores the brand names that supplied food, medicine, clothing, and weapons during the Civil War from the perspective of the producers. From du Pont’s gunpowder and Brooks Brothers’ uniforms to Procter & Gamble’s soap and Borden’s condensed milk, each company and product are investigated in detail. This study also touches upon how combat affected the companies, with each firm telling a tale that mirrors the war itself: family and friendships torn asunder, political intrigue, pitched battles, and paths crossed with the book’s namesake, Abraham Lincoln.
