Interestingly enough, there were no Federal Regiments dressed like this at 1st Manassas. Many accounts of "Zouaves", "Fire Zouaves", or "Ellsworth's Zouaves" at 1st Manassas ACTUALLY are referring to the 14th Brooklyn, and have dogged the fighting reputation of the 11th NY for 147 years now.

" ' Ellsworth! Remember Ellsworth!' was the chorused battle-cry with us all, and at each shout horsemen would fall from their horses, victims upon our altar of vengeance." -Member of Co, B, 1st NY Fire Zouaves, NY Leader, July 23, 1861.
