The pilgrimage to see the gravesite of Stonewall Jackson's amputated arm is very popular with Civil War buffs.

Here is the official National Park Service description of how his arm came to be buried on the grounds of Ellwood Estate:
"Here, in the Jones family cemetery, lie the remains of Stonewall Jackson's left arm. The general lost it during the Battle of Chancellorsville where he was mistakenly shot by his own troops. Surgeons removed the mangled appendage at the Wilderness Tavern field hospital on May 3, 1863 about a mile from here.
Jackson's chaplain, Rev. B. Tucker Lacy, visited the hospital to see Jackson and as he was leaving he saw the general's amputated arm lying outside the door. He gathered up the bloody limb and carried it across the fields to his brother's estate, Ellwood and buried it here in the family cemetery. In 1903 the granite marker was placed over the site."
