Blockade posture changes with the number of harbors, the ships available, and the larger strategy. A force kept beyond visual range may unsettle an opponent by leaving its exact position uncertain. Ships stationed close to the port can make their presence unavoidable. Regular signal-gun fire through the night could remind inhabitants that the cordon remained in place. A blockade can therefore apply pressure to morale and perception while restricting physical movement.

Choosing blockade posture for warning or intimidation
How closely ships hold a port depends on geography, fleet size, and whether commanders want concealment, warning time, or conspicuous psychological pressure.
