Part of the Mediterranean Sea along Italy's east coast, between the Italian peninsula and the Balkans: Bosnia-Herzegovina in Austria-Hungary, Montenegro, Albania, and Greece. At the southern end of the Adriatic was the Strait of Otranto.Austra-Hungary's seaports were all on the Adriatic — Pola, Cattaro, and Trieste, as were the Italian ports of Venice and Brindisi.With a more powerful navy than Italy, Austria-Hungary was able to shell the Italian coast, attacking coastal cities and transport.When Serbia was defeated in 1915, the Serbian Army retreated to the Adriatic coast. Italian ships transported them across the Adriatic to Italy and ultimately to Greece and the Salonica Front.The Entente allies tried to contain the Austro-Hungarian Navy within the Adriatic with submarine nets and mines across the Otranto Strait. On the night of May 14, 1917, the Austro-Hungarians made their most concerted effort to break the barrier in the Battle of the Otranto Strait. They were temporarily successful.
The Adriatic Sea is a sea in Mediterranean Sea.
