British Colonial Auxiliary Forces

The British Colonial Auxiliary Forces were the various military forces of Britain's colonial empire which were not considered part of the British Army proper. They were the colonial equivalents of the British "Home" Auxiliary Forces, and both Colonial and Home Auxiliary Forces were originally also referred to as "Reserve Forces" and as "Local Forces" and "Home Defence Forces" or "Defence Forces".

Definition

Whether a British military unit or corps was considered part of the British Army was ultimately decided by whether it received Army funds from the War Office. Within and without the British Isles, the British military by the end of the Napoleonic Wars included two regular forces : the Ordnance Military Corps, administered and funded under the Board of Ordnance, and the British Army, administered and funded under the War Office.
Most were Home corps and units, though some were raised in colonies. The regular forces also included at various times, usually in particular locations, invalid, fencible, and other units, utilised primarily for garrison or defensive duties. Some regular forces raised in colonies, such as those grouped in the Royal West African Frontier Force, were funded only by the Colonial Office or local governments and were therefore not considered part of the British Army. Additional to the regular military forces, the British military also included various reserve forces. The main ones by the time of the Napoleonic Wars included the Militia, mounted Yeomanry, and the Volunteer Force, although there were various others at different times and places.
The Militia system was duplicated in many colonies, many of which would also raise volunteer units. These reserve forces were under the control of local authorities and were locally funded. After the conclusion of the Napoleonic Wars and the American War of 1812, the British Government slashed defence spending and downsized the regular forces, disbanding the fencibles, disbanding the Volunteer Force in the British Isles, and allowing the Militia there to become a paper tiger. The Yeomanry was maintained as a back-up to the constabulary in maintaining law and order.
In the 1850s, the Crimean War highlighted the problems of British military organisation, leading to the abolishment of the Board of Ordnance, with its military corps and previously civilian departments of transportation, stores, etc. being absorbed by the British Army. The Indian Mutiny led to the abolishment of the East India Company, with the India Office taking over administration of India. The company's military forces were split, the white units being absorbed into the British Army and the native ones forming the Indian Army.
The British Army saw significant change through the latter half of the century. The British Army Regular Reserve was formed in the 1850s, following which, to avoid confusion, the Reserve Forces were generally referred to as the Auxiliary Forces or as the Local Forces. With the threat of invasion by France, the Reserve Forces in the British Isles were also re-organised throughout the latter half of the 19th century, into the first decade of the 20th century. The Militia was re-organised as a voluntary force from the 1850s, and the Volunteer Force restored as a permanent part of the peacetime military establishment. Both now included units other than infantry. These changes were copied to some degree in the colonial Reserve Forces. From the 1870s, administration and funding of the Auxiliary Forces in the British Isles passed from the lords lieutenant to the War Office and their units were increasingly integrated into British Army units. Although the Auxiliary forces remained organised as, and nominally, separate forces, their being funded by the War Office meant they were also considered parts of the British Army. Outside the British Isles, the funding of auxiliary forces remained largely with the local governments.
The first colonial units established in the British Empire were militia formations in England's American colonies. By the Victorian era, the colonial auxiliary military forces generally followed the pattern of the auxiliary military forces of the British Isles. There were also British military units, separate from those of the British Army that were raised and recruited in colonies, such as the Permanent Active Militia of the Province of Canada. These units consisted of professional soldiers. They supplied a reserve force either to be called up in wartime to reinforce regular British Army garrisons for home defence, or in some cases were entirely responsible for home defence. Many units, however, took part in active campaigns outside of the role of home defence in various conflicts the British Empire was involved in, including the two world wars.
Some of the reserve colonial units, especially in the strategically important imperial fortress colonies, were funded by the War Department out of Army Funds and considered part of the British Army, whereas others that did not receive Army Funds were considered auxiliaries.
Many colonial units started out as auxiliaries and later became regular units and forerunners to the current militaries of those colonies which have become politically independent. While most of the units listed here were army units, colonial marines were raised at various times, as were colonial naval and air force reserve units. Today, only four British Overseas Territories regiments remain : the Royal Bermuda Regiment; the Royal Gibraltar Regiment; the Falkland Islands Defence Force; and the Royal Montserrat Defence Force. The British Government is currently working with the local governments of the Turks and Caicos Islands and the Cayman Islands to raise reserve military units in those territories, also, with recruitment for the new Cayman Islands Regiment starting in January 2020.
