However, with these exploits of Marcellus one may compare the battles of Leuctra and Tegyra, greatest and most illustrious of actions; and we have no exploit of Marcellus accomplished by stealth and ambuscade which we can compare with what Pelopidas did in coming back from exile and slaying the tyrants in Thebes, nay, that seems to rank far higher than any other achievement of secrecy and cunning. Hannibal was, it is true, a most formidable enemy for the Romans, but so, assuredly, were the Lacedaemonians in the time of Pelopidas for the Thebans, and that they were defeated by Pelopidas at Tegyra and Leuctra is an established fact; whereas Hannibal, according to Polybius, Cf. xv. 11, 7 , where Hannibal makes this claim, in a speech to his men just before the battle of Zama (202 B.C.). was not even once defeated by Marcellus, but continued to be invincible until Scipio came.
