Did destroyer experience sharpen cruiser tactics?

Were the cruiser captains at River Plate former destroyer captains?

Several had destroyer experience, and Royal Navy personnel circulation between aggressive destroyer service and cruiser presence work helped preserve a balanced fighting culture.

Several officers in the River Plate cruiser force had destroyer backgrounds, and Commodore Harwood had considered using cruisers with destroyer-like aggression. The interwar Royal Navy placed its most aggressive officers in destroyers while cruisers carried much of the restrained presence workload. Moving personnel between the two communities helped keep the cruiser force from becoming purely diplomatic. Fleet design includes career paths and tactical culture as well as hulls.
