message from Gen. David B. Birney that there was a gap in the Union line, Kearny rode through a cornfield to reconnoiter. This brought him face to face with a line of Rebels, who shouted, "That's a Yankee officer! Shoot him!" Kearny ignored an order to halt and musket volley from the 49th Georgia regiment brought him down. By nightfall, neither side had broken through, and both fell back. The Union suffered approximately 1,300 casualties, with the Confederacy losing about 800. The bulk of the Union army was able to retreat further east towards Washington, ending Lee's attempt to fully defeat the Union army and thus protecting the capital from attack, but it came at a cost of many casualties and two important generals lost. Lee instead turned to Maryland, and fought the Battle of Antietam sixteen days later. History of the park John N. Ballard, a Confederate cavalryman during the Civil War who lost a leg serving under John S. Mosby, ended up owning much of the Ox Hill battlefield in the 1870s after marrying the heiress (Mary Reid Thrift). On July 7, 1915, Ballard and his wife deeded a small plot near the site of Stevens' death for the purpose of "allowing any person or persons the privilege of erecting appropriate monuments or markers commemorating the death of any Confederate or Federal Soldier who fell in the battle fought on the Fruit Vale Farm, this battle was fought on the 1st day of September 1862, being known as the Battle of Ox Hill or Chantilly." The plot was deeded to six trustees; three from New Jersey (Kearny's home) and three from Virginia. Trustees have since been appointed by court order. The monuments to Stevens and Kearny were dedicated on October 2, 1915, by the First New Jersey Brigade Society. In the 1980s, the area of the battlefield began to be commercially developed. The company which acquired rights to the park area wanted to move the monuments to a new location, but following opposition to this plan (including articles in The Washington Post), in 1987 the developer agreed to leave the stones in place and donated surrounding the monuments to Fairfax County. In 1994, the county purchased an additional . The rest of the battlefield is now completely developed. Signs designating the Ox Hill Battlefield Park were placed on the site, but little else was done with the park
