Franklin Kitchell Gardner (January 29, 1823 – April 29, 1873) was a Confederate major general in the American Civil War, noted for his service at the Siege of Port Hudson on the Mississippi River. Gardner built extensive fortifications at this important garrison, 16,000 strong at its peak. At the mercy of conflicting orders, he found himself besieged and greatly outnumbered. His achievement at holding out for 47 days and inflicting severe losses on the enemy before surrendering has been praised by military historians.
