December 13, 1862. The Washington Artillery of New Orleans was posted around the Marye House here on Marye's Heights. Col. J. B. Walton, the commanding officer, had his headquarters in the house. This unit and Alexander's Reserve Battalion, which relieved it during the afternoon, helped hurl back seven Federal charges. On May 3, 1863, Sedgwick's Federal VI Corps, attempting to join Hooker at Chancellorsville, successfully stormed these heights, only to be defeated at Salem Church, four miles west. During the Wilderness and Spotsylvania operations of May 1864, the Marye House served as a Federal hospital and the wounded lay outside under the trees, one of which, the large oak between you and the house, still stands.
