Then you might like "The Life of Johnny Reb" which is a description of the daily life of the Confederate soldier, taken from letters, journals, etc. There's a corresponding volume, "The Life of Billy Yank". Bell Wiley wrote the first, I think the second one too.
(I wrote my thesis on the American Civil War, so naturally I think it's pretty interesting, or I would have written about something else.)
Oh dear..........sorry to say, "THE LIFE OF JOHNNY REB" was not to my liking and I only read it because my daughter was forced to read it in the 7th or 8th grade ( she didn't like it either ) and I ALWAYS read the books assigned to her, so that we could talk about them.
But thanks for the suggestions; I appreciate your thoughtfulness.
