The battlefield was a scene of widespread destruction, covered with dead men and animals. The Chancellor family, whose house was destroyed during the battle, placed the entire 854-acre property for sale four months after the battle. A smaller version of the house was rebuilt using some of the original materials, which served as a landmark for many of the veteran reunions of the late 19th century. In 1927, the rebuilt house was destroyed by fire. That same year, the United States Congress authorized the Fredericksburg and Spotsylvania National Military Park, which preserves some of the land that saw fighting in the 1862 Battle of Fredericksburg, the Chancellorsville Campaign, the Battle of the Wilderness, and the Battle of Spotsylvania Court House (the latter two being key battles in the 1864 Overland Campaign).[79]

In May 2002, a regional developer announced a plan to build 2,300 houses and 2,000,000 square feet of commercial space on the 790-acre Mullins Farm, site of the first day of fighting at the Battle of Chancellorsville. Soon thereafter, the Civil War Trust formed the Coalition to Save Chancellorsville, a network of national and local preservation groups that waged a vocal campaign against the development.[80]

For nearly a year, the Coalition mobilized local citizens, held candlelight vigils and hearings, and encouraged residents to become more involved in preservation. Public opinion polling conducted by the Coalition found that more than two-thirds of local residents opposed the development. The survey also found that 90 percent of local residents believed their county has a responsibility to protect Chancellorsville and other historic resources.[81]

As a result of these efforts, in March 2003 the Spotsylvania County Board of Supervisors denied the rezoning application that would have allowed for the development of the site. Immediately following the vote, the Civil War Trust and other Coalition members began working to acquire the battlefield. By working with county officials and developers, the Civil War Trust acquired 140 acres in 2004 and another 74 acres in 2006.[82]
