Napoleonic Wars British Army - Infantry

British infantry battalions during the Napoleonic Wars comprised three different types of soldier. Eight of the 10 companies were ordinary Line Infantry, while two additional companies, one each of Grenadiers and Light Infantry either deployed on each flank (the Grenadiers on the right, the Light on the left) or detached to form a separate battalion, joining with the other flank companies of similar regiments.

The photos show the full battalion, then each of the three separate types individually.

(I don't yet have a battalion of Highlanders, so these couldn't be included.)
