When i started 4-5 years ago in civil war re-enacting we learned Hardee or Casey's . Then when Bull Run 150th was coming we all dropped that and went with Gilham's Manual. It was difficult to unlearn one manual and learn a new one. I looked last night at my Hardee manual and saw that it was printed in 1862. There must has been some lag time between the writing of the manual and the conversion to Hardee.
When do we start to switch back to hardee?
