River Plate command and adaptive thinking

Was the River Plate command decision genuinely out-of-the-box thinking, or a familiar destroyer-squadron method?

The method was familiar in destroyer work, but choosing to apply it from a cruiser-command context required a meaningful break with established expectations.

Destroyer experience supplied the tactical method, while using it in cruiser command required a break with established habits. Cruiser and destroyer commands carried different operational cultures, leadership styles, and expectations that officers were trained to respect. A cruiser-oriented officer still had to recognize that destroyer practice better suited the situation. The ingenuity lay in crossing that guarded professional boundary. The manoeuvre itself was already familiar in destroyer work.
