July 20, Adriatic Sea.
Lissa Island was the Austrian Empire's naval base in the Adriatic Sea.
After Italy declared war on Austria, it was eager to find a breakthrough on the battlefield, as the combat effectiveness of the Italian Army was notoriously inadequate.
However, the passage from Venice into Austrian territory was not suitable for large-scale marches, and earlier, the Austrian frontline commander had voluntarily withdrawn from Venice, which was difficult to defend, ensuring the main forces remained intact, using the terrain advantage to repel the attacks of the Kingdom of Italy multiple times.
The disadvantageous terrain indeed provided the Italian Army with an excuse, allowing them to evade this disaster.
As it was difficult to break through the Austrian Empire's defenses on land, the Kingdom of Italy sought to attack Austria by sea.
