Cause

In late 1940, Italy was actively transporting troops, equipment, and supplies from Brindisi to the Albanian ports of Valona and Durazzo to support offensive operations against Greece during the Italo-Greek War. Britain's Mediterranean Fleet sought to disrupt these supply lines as part of broader operations across the Mediterranean.

Event

On the night of 11–12 November 1940, British Force X—comprising three light cruisers and two destroyers—sailed north into the Strait of Otranto and intercepted an Italian convoy of four merchant ships guarded by two Regia Marina escorts returning from Valona. Force X sank all four freighters and damaged one escort without sustaining any losses.

Consequence

The destruction of the convoy with no British losses represented a clear tactical victory, temporarily disrupting Italian logistics to Albania. Force X subsequently rejoined the Mediterranean Fleet, which was simultaneously conducting the Battle of Taranto, compounding pressure on Italian naval operations in the region.
