In 1717, the Board established a Corps of Engineers, consisting entirely of commissioned officers. The manual work was done by the Artificer Companies, made up of contracted civilian artisans and labourers. In 1782, a Soldier Artificer Company was established for service in Gibraltar, and this was the first instance of non-commissioned military engineers. In 1787, the Corps of Engineers was granted the Royal prefix and adopted its current name and in the same year a Corps of Royal Military Artificers was formed, consisting of non-commissioned officers and privates, to be officered by the RE. Ten years later the Gibraltar company, which had remained separate, was absorbed and in 1812 the name was changed to the Corps of Royal Sappers and Miners.
