Vicksburg National Military Park preserves the site of the American Civil War Battle of Vicksburg, waged from March 29 to July 4, 1863. The park, located in Vicksburg, Mississippi, flanking the Mississippi River, also commemorates the greater Vicksburg Campaign which led up to the battle. Reconstructed forts and trenches evoke memories of the 47-day siege that ended in the surrender of the city.
