Why the world's largest navy was still short at Imbros

The Imbros episode exposes a fleet-availability problem larger than the immediate tactical failure. The Royal Navy had to replace losses, cycle ships through maintenance, keep the Grand Fleet ready against the High Seas Fleet, and meet commitments in the Adriatic, Aegean, and wider world. Those demands left even the world's largest navy short of suitable ships at a vulnerable point. The available response force had been withdrawn to refit and restock before other operations because planners believed there was time. One ship left behind would probably only have added another loss, while keeping the whole mixed force present would have meant accepting risk elsewhere. Wartime commanders had to choose between competing dangers with the ships actually available rather than the fleet they would have preferred.
