Appian of Alexandria Civil Wars 3.2.9

[9] Octavius, the son of the daughter of Caesar’s sister, had been appointed master of Caesar’s horse for one year, for Caesar at times made this a yearly office, passing it around among his friends. Being still a young man, he had been sent by Caesar to Apollonia on the Adriatic to be educated and trained in the art of war, so that he might accompany Caesar on his expeditions. Troops of horse from Macedonia were sent to him by turns for the purpose of drill, and certain army officers visited him frequently as a relative of Caesar. As he received all with kindness, an acquaintance and good feeling grew up by means of them between himself and the army. At the end of a six months’ sojourn in Apollonia, it was announced to him one evening that Caesar had been killed in the senate-house by those who were dearest to him, and were then the most powerful ones under him. As the rest of the story was untold he was overcome by fear, not knowing whether the deed had been committed by the Senate as a whole or was confined to the immediate actors; nor whether they had already been punished by the people, or would be, ¹ or whether the people were pleased with what had been done.
