The militia, a county-based, part-time reserve force, was the oldest component of the British army. It can trace its origins back to the Anglo-Saxon Fyrd, while at the time of the Civil War the county militia units were known as "The Trained Bands". The London Trained Bands were Parliament's best force until the appearance of the New Model Army. The problem, for local historians, is that the militia was only embodied in times of national crisis, after which they were stood down. The Westminster Militia would have been embodied during the Napoleonic War and stood down thereafter, so the element of continuity is somewhat tenuous - the link with the Fusiliers came later as part of the "Cardwell Reforms". The early 19th century Westminster Militia (the 35rd Middlesex) was a typical county militia regiment, which became the "Royal Westminster Militia" in 1804.
