all of which would be absorbed into the Royal Artillery on or after its 1716 formation, and the Royal Engineers (an officer-only corps responsible for planning naval and military works in garrisons and on expedition), both of which, with the civilian-staffed stores, transport, Commissariat, and other departments were all parts of the Board of Ordnance, and the English Army (after 1707, the British Army), composed primarily of cavalry and infantry. The Horse and Foot Guards were considered parts of the British Army, though falling under the Royal Household there were differences in their command and administration. There were also other minor forces of little military significance, such as the Yeomen of the Guard. The reserve military forces included the Honourable Artillery Company and the Militia (or Constitutional Force), which was normally an infantry-only force until the 1850s. To these would be added the mounted Yeomanry and the Volunteer Force, though the latter existed only in wartime until the 1850s. Similar reserve forces were raised throughout the British Empire. The reserve forces were auxiliary to the regular forces, and not parts of them. They were under the command of local representatives of the Crown (expressed as the Monarch, although by the 19th Century the Monarch had become a figurehead for the British Government, which was responsible to Parliament). In the British Isles, the reserve forces were controlled by Lords Lieutenant of counties until 1871, when the British Government took direct control. In the British colonies (which refers to those administered from 1782 to 1801 by the Home Office, from 1801 to 1854 by the War and Colonial Office, from 1854 to 1966 by the Colonial Office, from 1966 to 1968 by the Commonwealth Office, from 1968 to 2020 by the Foreign and Commonwealth Office, and since 2020 by the Foreign, Commonwealth and Development Office, and not to protectorates, which fell under the purview of the Foreign Office, or to British India, which was administered by the East India Company until 1858, and thereafter by the India Office), the Governors were generally appointed also as Captains-General or Commanders-in-Chief with similar powers to Lords-Lieutenant (in some colonies, notably Imperial fortresses such as Bermuda, the Governor was always a senior naval or military officer who also had control of units of the regular forces). The Reserve Forces were originally for local service, embodied for home defence in times of war or emergency. During the
