They were nicknamed De Kalb Regiment.

The regiment was formed from German immigrants from both New York and Pennsylvania.

It consisted of a dark green frock coat with red trimming and cuff flaps, dark green pants with a red stripe down the leg, a dark green kepi with a red band, and black shoes.

This uniform consisted of a dark blue zouave jacket with red trimmings, dark blue pantaloons[2] with red braiding, a sky blue sash, a dark blue zouave vest with red trimming, a red tasseled fez with a thin yellow band around it.

Dark blue Zouave panatloons were worn with a red stripe on the outseam tucked into deerskin jambières, and white gaiters made from canvas or drill (fabric).
