But the 23rd uniforms are specifically that, the 23rd. Different regiments have different facing colours and a centre company of most other regiments would not have the elite wings. Regiments in which all companies have elite wings are mainy fusiliers (like the 23rd) and lights.Those elite wings are because they represent a guard company. lmao... They are not specific to a regiment.
There were no 'guard' companies, only flank companies (lights and grenadiers). The term 'guard' is only applied to foot guard regiments, and have nothing to do with fusiliers or any other internal battalion structure.
Additionally, I never claimed that wings were specific to a regiment, so you are misrepresenting what I said. The matter of fact is, that all companies in fusilier regiments, even the centre/battalion companies, wore grenadier company distinctions.
Grenadier distinctions means that they have the wings aswell as a white plume (in contrast to light companies, which wore wings and had green plumes). It is correct that these wings would only be given to 2/10 companies in battalions of a regular regiment of foot. But fusiliers are special. There are always exceptions to the rules in the British army, which is why many regiments were so unique.
So, just like highland line regiments had all their soldiers wear kilts, fusilier regiments had all their soldiers wear grenadier company distinctions. This orginates from the fusiliers being raised as the first regiments to receive flintlock muskets. When all regiments started to use this musket, the fusiliers were no more special than any other regiment in terms of equipment. However, they still held on to their tradition of being organised essentially as grenadier regiments in all but name; all of their companies held the grenadier status in terms of uniform distinction.
Holdfast is the first case in which I have seen a napoleonic fusilier wear a red-white plume, which was the plume usually worn by centre companies, but not for fusiliers. I have found no material thus far which would indicate that fusilier centre companies would wear the plumes of standard centre companies. Either the developers have found something I don't know about the 23rd, or they might have assumed they would wear the regular plumes. I don't feel qualified to claim that this is right or wrong, though. Nevertheless, as stated, the fact that they all have elite wings is spot on.
Even the light company of a fusilier battalion might have worn white instead of the usual green plumes, but I have found no evidence pointing in either direction on this. They also had some other differences such as having Second Lieutenants instead of Ensigns.
