A small navy could raise a few destroyers to a new standard quickly, but the Royal Navy also trained while cruising, operating, and returning to harbour. Polish and other allied crews working alongside British destroyers could therefore encounter the same exercises rather than waiting for a separate formal course. This routine reflected the empire-wide requirement to be ready for battle in many theatres with little warning. Repeated practice carried doctrine from expert flotillas into a wider operating culture.

Routine exercises kept night fighting from becoming a specialist trick
Continuous exercises at sea and from harbour let allied destroyer crews absorb night practice as part of ordinary readiness.
