Blockade!!

Blockade long predates Rome and belongs to the basic practice of warfare wherever organized naval forces could control movement by water.

A close blockade sits outside the enemy port, but the ships required depend on whether the target is a battle fleet, merchant traffic, or a privateer base.

An inshore squadron can imitate a fleet over the horizon, or conceal a real one, by controlling when it signals and encouraging the enemy to confirm the wrong assumption.

Distant blockade becomes more disruptive when production depends on components, additives, and raw materials moving through global maritime chokepoints.

Blockade requires practical sea control, and surface ships usually carry the burden of stopping, searching, and policing merchant traffic.

German submarine campaigns in both world wars attempted to blockade Britain through minefields or ocean-wide interdiction guided by intelligence and command control.

Napoleon could forbid European trade with Britain on paper, but merchant crews, weak tracking, and French loss of sea control made the prohibition hard to enforce.

Coppered hulls helped Royal Navy ships catch valuable blockade runners, while captured ships and cargoes fed prize incentives and Admiralty finances.

Runners could hug the coast, use shallow-draft speed, or claim neutral status, forcing blockaders to balance interception against diplomatic risk.

Steam propulsion freed runners from favorable winds and tides, shifting interception toward channel depth, engine power, and navigational markers.

The logistics chapter explains how food, livestock, vegetables, refit cycles, and relief ships kept a blockading fleet on station.

Royal Navy ships sometimes left weak French islands untouched and bought water, fruit, and vegetables from their inhabitants instead.

Toulon's blockade shows why the Royal Navy sometimes risked third-rate ships close inshore when the enemy fleet was dangerous enough.

The opposing orders of battle show why Britain kept first- and second-rate ships concentrated against Toulon while the War of 1812 continued across the Atlantic.

French commanders used favorable winds to exercise outside Toulon, while Edward Pellew held the main fleet back in hopes of cutting them off for battle.

On 5 November 1813, a sudden northwesterly wind left the French advanced squadron to leeward and prompted Henry Heathcote's inshore force to attack.

Both fleets fired high to damage masts and rigging until the French reached shore-battery protection, leaving light casualties but important tactical lessons.

Even after Pellew withdrew much of the fleet to Majorca, the French remained cautious because the sudden British reinforcement had made the blockade seem tighter than it was.

Because warships spend more wartime on blockade, commerce protection, and convoy work than in fleet battles, those routine missions must shape force design.

Allowing merchant traffic into a blockaded naval port can preserve the enemy fleet by feeding its sailors and replacing water, rope, clothing, and other stores.
