The Roman History: Macedonian Affairs (XVI)

[*] Perseus, having already gradually plucked up courage [*] after his flight, wickedly put to death Nicias and Andronicus, whom he had sent with orders to throw his money into the sea and to burn his ships; because after the ships and money had been saved he knew that they were witnesses of his disgraceful panic and might tell others of it. And from that time, by a sudden change, he became cruel and reckless toward everybody. Nor did he show any soundness or wisdom of judgment thereafter, but he, who had before been most persuasive in council and shrewd in calculation and courageous in battle, barring his inexperience, when fortune began to change became suddenly and unaccountably timid and imprudent, as well as changeable and maladroit in all things. Thus we see many who lose their usual discretion when reverses come.
