Banks, who works for ESPN, also has two excellent posts featuring Maria Hall, a Connecticut nurse known for her loving care of wounded soldiers at Smoketown hospital near Antietam Creek and elsewhere. That is the subject of the more recent of Banks's posts; the other is about her association with the family of Abraham Lincoln.
It was Hall who cared for the wounded Elmer Bragg, a Vermont soldier who served in the 9th New Hampshire, after Bragg's release from a rebel prison camp in 1864. She was then working at the military hospital at Annapolis. Her touching letter to Bragg's father after Bragg died is quoted in Our War and in this blog post.
