The Battle of Lissa was fought on 20 July 1866 between the Italian and Austrian navies near the island of Lissa in the Adriatic Sea during the Third Italian War of Independence. An Italian fleet under Admiral Carlo Pellion di Persano engaged an Austrian fleet led by Vice-Admiral Wilhelm von Tegetthoff in an attempt to break Austria's naval dominance in the Adriatic. The battle was the first in which ironclad warships were used on a major scale. Both fleets exhibited several technical deficiencies, while the Italian fleet also suffered from severe rivalries between its officers. The Austrians were victorious, relieving Lissa after sinking two Italian warships, in part by using naval ramming tactics. Persano was disgraced upon his return to Italy, while Tegetthoff received widespread praise and accolades for his victory.
