The Adriatic's long, enclosed shape made local actions unusually intimate and vicious while limiting where Austro-Hungarian ships could go. A cul-de-sac with one main entrance captures the strategic problem. That geometry concentrated patrols and raids while making the Strait of Otranto the obvious place for an Allied barrier. It also magnified the value of mines, submarines, torpedo craft, coastal bases, and short-range attacks close to home waters.
