Notall Civil War soldiers were bean poles, but fat ones didn't last very long - especially in thecombat arms. Bugles were not even regulation for forage caps. Many Reenactors may alsobe surprised to learn that bugles and the side eagle plate were not issued with the Hardeehat. They had to be requisitioned separately. Once the war got going, soldiers rarely didso unless they were on special guard detachments behind the lines.
Feathers are also wrong.
I have yet to see any original photo of a field soldier wearingone. Hat cords were worn sometimes on Hardees, but since they also had to be obtainedseparately, probably not that much. The best way to go by far is to have a plain hat or forage cap. Take a long, hard look atyour headgear. Nothing will make your impression like a good, correctly-styled hat.
