De Brock became a check on Beatty

Osmond de Brock wrote an unofficial report that changed how several senior officers viewed Beatty's performance. De Brock later served as Beatty's flag captain in the Grand Fleet. Jellicoe placed him there in part to watch and manage the commander from inside the staff structure. The appointment suggests an institutional response built around trusted staff oversight rather than public punishment. It also explains how Beatty's later command could function better without assuming that his underlying habits had disappeared.
