Hi,
The Royal Staff Corps was established by the Duke of York in 1799 as a result of a lack of co-operation of the Board of Ordnance (who liked to be independent of the C in C) in supplying technical troops such as Engineers. It was made up of five companies, each of a Captain, three Subalterns and fifty Artificers. The officers were considered to be part of the Quatermaster General's Staff. In the Peninsular War they were used by Wellington to supervise support works such as bridge repairs , while the Royal Engineers were used in front line duties such as sieges. The lack of trained Engineer officers often resulted in the Royal Staff Corps overseeing work being done by untrained labour (often infrantry soldiers), such as the Royal Military Canal. The corps shrank after the Napoleonic wars and disappeared in 1830, when all remaining offers and men transferred to the Royal Sappers and Miners.
