Julius Caesar and the Pirates of Cilicia

At the age of 19, Julius Caesar was captured by the Pirates of Cilicia and ransomed.
After he had been freed, Julius Caesar returned and had all his captors crucified.

81 BCE As a young man of 19 years old, Caesar was seized by the Pirates of Cilicia on route from Rome to Rhodes.
He was ransomed for an extortionate 50 Talents.
He was held for forty days on the island of Farmaco (Pharmacusa), east of Limnos.
Here he joked that he would have them all crucified after his release.
After the ransom had been paid and he was released, Caesar went to Miletus where he hired a fleet of 4 vessels with 500 Legionaries in each boat.
He then returned to Farmaco, located his 30 captors, capturing 350 in all, and delivering them to Marcus Junius, the Governor of Asia in Pergamun, where they were imprisoned.
When the Governor hesitated to put them on Trial, Caesar returned to the prison, removed them and had them all crucified. In a display of mercy, to avoid a protracted death, he ordered their throats to be cut.
