The Otranto raid highlights a fundamental asymmetry in blockade operations. The attacker can overhaul ships in harbour, conceal the timing of a sortie, and concentrate its best available force for one chosen moment. The blockader must keep enough vessels continuously on station while also retaining a response group strong enough to intervene. This persistent requirement can give a smaller navy a temporary local advantage without eliminating the blockade as a whole.

The Otranto raid illustrates how an attacker can mass ships at a chosen moment while a blockader must sustain both the patrol line and a response force.
