- Headquarters of Union generals Grant and Sherman during the Vicksburg Campaign
- National Park
This 470-acre farm contains the historic Dillon Plantation, which once served as the headquarters for both Union Generals Ulysses S. Grant and William T. Sherman during the Battles of Raymond, Jackson, and the Siege of Vicksburg in 1863.
Besides being headquarters for them, it's also where, on May 12, 1863, General Grant signed an order that would change the course of the war. After hearing that the Battle of Raymond, just six miles to the east, had been won by the Union under General James B. McPherson, Grant "decided at once to turn [my] whole column towards Jackson and capture that place without delay."
The move towards Jackson was a surprise for Confederate General John C. Pemberton who was expecting Grant to attack from the direction of Dillon's. On May 14, Grant surprised Pemberton again with an attack from the east and two days later, defeated the Confederates in the Battle of Champion's Hill, a victory that sealed the fate of Vicksburg.
Acquired by the National Park Service in 2003, the site, located along the Mississippi stretch of the Natchez Trace Parkway, is not currently open to the public.
