British units wore the stovepipe shako during the peninsular war. Light companies were distinguished by green plume and wings, grenadiers by a white plume and wings, and line companies by a red over white plume and tufts on the shoulder boards. The Waterloo shako was introduced in 1809 and all units except the 28th and the rifle battalions generally switched. The plume and cording colors remained the same.

As for the fusiliers - yes, they wore bearskins, but most sources contend they did not wear the bearskin caps into battle. We'll answer your questions this way: The British organization consisted of three types of regiments.

1) Line - 1 light company, 8 line companies, 1 grenadier company
2) Light - 1 light company, 8 line companies, 1 grenadier company
3) Rifle - 10 rifle companies

In the peninsula the light companies were detached from the line and light regiments and acted as skirmishers along with the rifles. The grenadiers were not formed into a separate battalion as the French.

Most wargames use the rifle (60th & 95th) and the light infantry battalions (43rd, 52nd, 71st, etc.) as light infantry units with light infantry movement and powers (faster movement and less melee powers). Usually the Scottish battalions (42nd, 79th, 72nd, 78th, 91st, 92nd) are classified as elite units - equivalent to French grenadiers. We use a ratio in wargames of I light to 4 line to 1 grenadiers. Double this number of units and you are allowed 1 guard unit.

Concerning the French: Six companies to the battalion (light and line). The light battalions were used either as skirmishers or, as line battalions. The Voltigeur companies of the line battalion were used as skirmishers. Generally in wargames Voltigeur and grenadiers are brigaded into battalions. The same applies to the light battalions. Then again, it depends upon the rules you are using - as to how to use your troops!!
