The Battle of Lissa or Battle of Vis (Croatian: Bitka kod Visa) took place on 20 July 1866 in the Adriatic Sea near the Dalmatian island of Vis (Lissa in Italian) and was a significant victory for a fleet of the Austrian Empire over a numerically superior Italian. One of the main reasons for this poor performance was the internal rivalry between the commanders of the Italian fleet and, as a consequence, the Italian admirals Albini and Vacca, with their ships, did not face the enemy during the entire battle. We understand that the Austrian maneuver was consistent and the best possible according to the available means, and also had luck in its favor and the failures of the Italian fleet. So let s test a hypothesis in which the latter will have its main tactical shortcomings corrected.
