Appian of Alexandria Civil Wars 3.3.26

[26] While these things were taking place at Rome, Cassius and Brutus were collecting troops and money, and Trebonius, who was governor of the province of Asia, was fortifying his towns for them. When Dolabella arrived, Trebonius would not admit him to Pergamus or Smyrna, but allowed him, as consul, to occupy a market-place outside the walls. When the latter attacked the walls with fury, but accomplished nothing, Trebonius said that he would be admitted to Ephesus. Dolabella started for Ephesus forthwith, and Trebonius sent a force to follow him at a certain distance. While these were observing Dolabella’s march, they were overtaken by night, and, having no farther suspicions, returned to Smyrna, leaving a few of their number to follow him. Dolabella laid an ambush for this small number, captured and killed them, and went back the same night to Smyrna. Finding it unguarded, he took it by escalade. Trebonius, who was captured in bed, told his captors to lead the way to Dolabella, saying that he was willing to follow them. One of the centurions answered him facetiously, Go where you please, but you must leave your head behind, for we are ordered to bring your head, not yourself. With these words the centurion immediately cut off his head, and early in the morning Dolabella ordered it to be displayed on the praetor’s chair where Trebonius was accustomed to transact public business. Since Trebonius had participated in the murder of Caesar by detaining Antony in conversation at the door of the senate-house while the others killed him, the soldiers and camp-followers fell upon the rest of his body with fury and treated it with every kind of indignity. They rolled his head from one to another in sport along the city pavements like a ball till it was completely crushed. This was the first of the murderers who was visited with such punishment. ¹
