- He fought in the Army of Northern Virginia under General Lee, according to family history; what unit is unclear.
According to Hall's narrative about his father, "When the Civil War broke out, father went South. He went to Morgantown and crossed over the Potomac to Wakefield, which was the home of his friend, Mrs. John Wilson. . . . From there he joined General Lee's army. We never heard much of my father's military career from him; he considered that Lee's surrender at Appomattox had settled everything. He often laughed at the military titles the old Confederates used to hold onto. I remember once when I was about ten years old, we were driving with father, when we met a carriage. A strange lady leaned out of the carriage and said, "How do you do, Major Hall." I asked my father, "Were you a major?" He replied, "Yes, I was a major in the Confederate Army." That was the first I had ever known of it. I do not think I ever heard him mention it again.
I was told by one of his nieces that he was promoted for bravery on the battlefield. His general presented him with a pair of gold spurs, on this occasion. I never saw the spurs, and never heard of him speak of them. I presume they were stolen from him, when he kept bachelors hall at Beersheba. . . . .
My father was wounded at Cold Harbor; he had a dent in his leg from it, but was not lame. He came through the lines twice, and came home. The second time he did this, my grandfather notified the military commander of the district, and he was arrested and taken prisoner, and confined in Fort McHenry. He almost died of typhoid fever and lice there. He often said that he had three doctors and the devil fighting over him; fortunately the doctors won out. This was very near the close of the war. When he recovered he was very weak, and as the war was about over, he acepted a parole and came home. My grand-father's reason for notifying the authorities was that, if my father had been found at his father's house, my grand-father's property would have been in danger of being confiscated by the Federal Government."
