1st Battalion of Grenadiers

For the war against the rebels in the American colonies two battalions of grenadiers were formed. The First Battalion of Grenadiers consisted of ten grenadier companies from different British infantry regiments. 

It was commanded by Lt. Colonel William Meadows of the 55^th Regt. and Major Edward Mitchell of the 5^th Regt.

The soldiers wore the uniforms of their parent regiments. So you can find eleven different facing colours altogether: The 55th of the Lt. Colonel had blue green facings and golden lace and buttons.
The ten companies were clad like this:

No.	Name	Facings
4th	King’s Own	Blue
5th	Northumberland	Gosling Green
10th	North Lincolnshire	Pale Yellow
17th	Leicestershire	White
22nd	Cheshire	Buff
23rd	Royal Welsh Fuzileers	Blue
27th	Inniskilling	Pale-Buff
35th	Sussex	Orange
38th	1st Staffordshire	Yellow
40th	2nd Somersetshire	Buff

According to the regulations of Royal Clothing Warrant the musicians of the different companies were dressed in different uniforms: The drummers and fifers of the regiments with blue facings had red coats, the others had coats in the facing colours. And there were differences on the backs of the grenadier caps.

I tried to use figures of different producers. So you will find miniatures by  Fife & Drum Miniatures, Old Glory (2nd Edition), Perry Miniatures, and Wargames Foundry.
