The regiment was issued with Zouave uniforms. Brigadier General Kenner Garrard had been working since the fall of 1863 to have the regiments of his brigade learn French Zouave light infantry tactics, and rewarded them with the right to wear the uniform. It consisted of a blue Zouave jacket and matching baggy trousers, ten foot red wool flannel sash, and a tassled red fez (or turban on dress occasions). The unfiforms had been adopted from French Chasseur unfiroms that had to be modified for the larger men of western Pennsylvania. The 155th wore, and apparently liked, the colorful uniform until the end of the war. |
