About this report
A strait is a line of water between two shores. This is its nature, and in it lies the whole secret of its politics. A fleet can cross a passage, and can even watch it for a time, but it cannot hold it: sooner or later it must coal, repair and anchor somewhere. To control a strait in a stable and permanent way one must possess its shores, command a base on the nearby land, and very often dominate its hinterland.
The control of a maritime passage, in other words, is not merely a naval undertaking; it is a territorial one. This is why the British Empire, which rested upon the control of the world’s great straits, was driven to occupy, one after another, the lands that surrounded them.
Key questions this report answers
- Why, on the report's thesis, can a strait not be held from the sea but only by possessing its shores and hinterland?
- How do the cases of Gibraltar, Malta, Cyprus, Aden, and Singapore illustrate the territorial logic of controlling maritime passages?
- What does the Dardanelles counter-case reveal about the limits of naval power without control of the surrounding coast?
- What contemporary lessons for chokepoint control and overseas basing follow from the British Empire being an empire of coasts?
Inside this report
- Why a strait cannot be held from the sea
- Gibraltar: the rock and the harbour
- Malta and Cyprus: the island fortresses
- Aden: the seized port that guarded the Red Sea
- The Cape and Singapore: the shores of the ocean routes
- Egypt: occupying a country to hold a canal
- The counter-case: the Dardanelles
- The rule: the empire of passages is an empire of coasts
