Wellington's small but specialised staff

Did an army the size of Wellington's require a large general staff?

Wellington did maintain a staff, but it was smaller and more specialised than later general-staff systems, with engineers and artillery officers prominent.

Wellington did not command a large army without staff support. The organisation was smaller than a later general-staff system and is discussed less often, but specialist officers still performed essential staff functions. Engineers and artillery officers appear prominently because planning movement, fortification, fire support, and technical work required their expertise. Unlike many line officers, these specialists generally earned their positions through technical ability rather than purchasing commissions, which also made them less likely to come from the most socially prominent families. These specialists supplied the professional machinery behind a commander whose public image can otherwise make his army appear like a one-man operation.
