Paul from Hull, sorry to contradict, but the Duke of Wellington's Regiment, the 33rd, were amalgamated with another, I think the 76th, in 1969.

To add my two penn'orth to the debate on bearskins; the original mitre cap worn by grenadiers, which seems purpose-made to fall off, was replaced by the time of the American War of Independence by a much lower model, which had a fur edging to the front plate. It is usually referred to as a "Grenadier Cap". (British) Regiments of Fusiliers wore this also.

The whacking great fur edifice on top of Napoleon's Garde (and British Guards since Waterloo) is a rather fantastic development of this Grenadier Cap. It would obviously be most unsuitable for fighting in the woods of North America, but it gave a man more apparent height and presence on battlefields in Europe.

During the French and Indian Wars (1756 - 1760), some British (and "Colonial") Light Infantry units wore a leather or stout cloth cap very like a deerstalker, complete with earflaps. By the time of the War of Independence, it had sprouted a less-than-practical decorative front plate, and a plume.

I seem to recall that during the Anglo-American War of 1812, one Canadian light infantry unit, the "Voltigeurs", wore a small bearskin, barely larger than a jockey's cap; this would have been both more prestigious and more practical than a foot-high "stovepipe" shako.
