A starting point for studying gunboat diplomacy

Which book is a good starting point for studying forceful naval diplomacy?

James Cable's Gunboat Diplomacy, 1919-1979 is the recommended foundation.

James Cable's study of gunboat diplomacy from 1919 to 1979 explains how governments employ ships for political pressure short of full-scale war. Its chronological scope supports comparison of visible maritime force across very different crises. The focus on limited political effects distinguishes gunboat diplomacy from general naval strategy and fleet battle. Cable had served as an army officer and diplomat before writing about naval diplomacy.
