A flag captain gives an admiral both a trusted confidant and an officer who can keep the flagship functioning as part of a larger command system. Illness, injury, or overload do not remove responsibility from a commander, so a capable staff must be able to transfer duties or preserve continuity when necessary. The chief of staff or flag captain becomes the commander's representative in rooms the admiral cannot attend and ensures information moves in both directions. When the same officer also commands the flagship, that relationship must coexist with responsibility for the ship itself. Nelson's service aboard HMS Captain shows how command effectiveness depends on this institutional partnership rather than on a solitary great man.
