The original fusiliers in the British Army were The 7th Foot, Royal Regiment of Fuzileers raised in 1685. This subsequently became The Royal Fusiliers (City of London Regiment). The original purpose of this unit was to act as escort to artillery guns, as well as keeping discipline amongst the civilian drivers. Both Scots (21st Foot) and Welsh (23rd Foot) regiments also became fusiliers in the period up to and including 1702 and all three regiments were distinguished by the wearing of a slightly shorter version of the Mitred Cap worn by Grenadier companies of all other infantry regiments. A number of additional infantry regiments were subsequently designated as fusiliers during the 19th century, but this was simply a historic distinction without any relationship to special weapons or roles.
