Dark blue forage hat (kepi) - The forage cap worn by most Union soldiers was made from wool broadcloth.
I would not have been surprised if the stones we bowled had pitched near a rusty saber or a blue or gray kepi.
Every visitor to Paris is familiar with the rather theatrical-looking policeman, in his short frock-coat or cape, smart kepi cocked on one side of his head, and with a sword by his side.
The forage hat, also known as a kepi, was worn for fatigue duty, while other hats were designed to be worn for dress.
