The book, "Black Southerners In Gray" is a collection of essays on Black Confederates. Thomas Y. Cartwright authored one about the men that served with N.B. Forrest. He mentions how much confidence Forrest had in Preston Roberts who served "unofficially" as a Quartermaster. He was in "charge of all funds for food, and was in command of 75 cooks." He asks several questions in this book that's over 20 years old. Maybe someone now has the answers to "Did he go to war with Forrest in 1861? What State was he from? Where did he live following the war ? Where was he born ? Where is he buried ? Was he a free man before the war ? Apparently he never filed for a pension. Mr. Cartwright (at least back then,) seems to be saying there was little documentation on him. I'd also love to see his photo.
