My great, great, great grandfather John Stover Hays was a member of the 39th Virginia Cavalry Battalion, Company A. His widow's pension application says that he lost an eye in the Battle of Gettysburg. She also lists references as: Major John H. Richardson and Captain Augustus P. Pifer.
Hays referred to himself as "Captain" and has it inscribed on his tombstone, but I could not find any listing of a John Hays in the NPS website.
A genealogist named Gregg Carter from Richmond from some time ago left us with a report that said: "According to Hays' commander, Lee asked for Hays whenever he wanted some special duty performed." It does not list who the commander was.
Any insight into how I could search for that text would be most appreciated!
