Strategic Narrative Overview
Ship numbers fluctuated as both sides were constrained by wider Mediterranean commitments. The campaign's defining personalities were British captain William Hoste and French commodore Bernard Dubourdieu. Their rivalry climaxed at the Battle of Lissa in March 1811, where Dubourdieu was killed and his squadron defeated. This action handed Britain effective naval dominance, enabling British and Greek forces to seize fortified French islands and devastate coastal trade.
01 / The Origins
French dominance in the Adriatic followed the Treaty of Pressburg (1805) and was consolidated after the Treaty of Tilsit (1807) forced Russia out of the Septinsular Republic. France controlled Venice's naval yards and needed the Adriatic for troop convoys to Illyria, vital for a secret Tilsit clause promising support to Russia against the Ottomans. Britain resolved to sever these supply lines and break French hegemony, launching sustained naval operations from 1807.
03 / The Outcome
Following the 1811 reversal, France abandoned its eastern Ottoman strategy, redirecting the Grande Armée toward Russia. British forces maintained pressure until the Sixth Coalition's advancing armies expelled France from the Adriatic coast in early 1814. British troops and marines assisted in capturing Fiume and Trieste, completing the elimination of French influence across the region and restoring Austrian access to the Adriatic.
