Кварнер
On July 30 of that year, Sauro's boat was sent over to carry out a sabotage in the Hungarian port of Fiume (now Rijeka in Croatia), but it crashed into a rock in the Kvarner Gulf. The crew was intercepted by the Austro-Hungarian destroyer "Satellit", and imprisoned. Sauro was recognized and placed on trial for his previous act of treason, and, after facing a military tribunal in Pola (now Pula in Croatia) was sentenced to death and hanged.
