The man who runs away will fight again.

post deinde aliquanto tempore Philippus apud Chaeroneam proelio magno Athenienses vicit. Tum Demosthenes orator ex eo proelio salutem fuga quaesivit, cumque id ei quod fugerat probrose obiceretur, versu illo notissimo elusit: ἀνὴρ (inquit) ὁ φεύγων καὶ πάλιν μαχήσεται. | Then some little time afterwards Philip defeated the Athenians in the great battle at Chaeronea. At that time the orator Demosthenes sought safety in flight from the battlefield, and when he was bitterly taunted with his flight he jestingly replied in the well-known verse: The man who runs away will fight again. (tr. J. C. Rolfe, 1927) | Also in the Monosticha attributed to Menander, no. 56 Jäkel. However, linguistic evidence in the cited Greek verse suggests a date of composition considerably later than Demosthenes' time (T. Kock, 1886:98).
