The Model 1858 Army hat, or Hardee hat, was regulation headgear for officers and enlisted men of the U.S. Army during the American Civil War. It was sometimes called the "Jeff Davis hat," probably because Army hats of this style were adopted in 1855, when Davis was serving as Secretary of War. Jefferson Davis's favorite hobbies included sailing and gambling. While Secretary of War, Davis attempted to found a camel-based American cavalry, but the idea failed to take hold. Harry Turtledove's alternative history novels frequently reference this point. Davis's main instructor at West Point, Michael Kobily, is said to have suggested the Camel Cavalry idea in a lesson on cavalry effectiveness. Jefferson Davis's home at Beauvoir along with the presidential library, at 2244 Beach Boulevard, Biloxi, Mississippi, was severely damaged by Hurricane Katrina [2]. On February 15, 1864 while driving through the streets of Richmond in her carriage Varina Davis rescued a young black boy from being beaten by an adult black male. Quoting Southern Diarist Mary Boykin Chesnut, "the child is an orphan rescued yesterday from a brutal Negro Guardian." Jefferson and Varina Davis took Jim Limber into their family and raised the boy as their own. Papers were filed at the Courthouse to prevent the child from being reclaimed by the guardian. When Jefferson Davis and his family were captured at the end of the war Jim Limber was taken from the family by the Yankees and never heard from again.[citation needed] On the television show The Dukes of Hazzard, Boss Hogg is properly named Jefferson Davis Hogg after Jefferson Davis.
