Fleet functions beyond fighting the enemy fleet

A passage from Corbett's war course broadens the purpose of sea power beyond a single fleet engagement. Fleets can assist or hinder military operations ashore, secure or destroy commerce, and influence whether neutral powers enter a war. Corbett's War of the Spanish Succession examples show Rooke using naval operations to influence Savoy and Portugal, while Nelson's Mediterranean activity helped sustain the alliance with Naples. In each case, the politically decisive use of a fleet could matter more than destroying an enemy squadron at that moment. The passage demonstrates how maritime strategy connects naval movement to diplomacy, coalition warfare, trade, and land operations.
