The Persian Empire maintained control over its Greek subjects through indirect rule, propping up local strongmen known as 'tyrants.' These rulers were loyal to Persia because the empire was their sole source of power, making them effective but vulnerable puppets against a populace that resented them.

Roman diplomats employed a strategy of bad-faith negotiation to cripple Carthage's defenses. They first demanded the surrender of all weapons, implying this would suffice. Only after Carthage was completely disarmed did the Romans reveal their true, non-negotiable demand: the city's total destruction.

Victory hinged on opportunism, not just courage. Athenian general Miltiades attacked only after intelligence confirmed the Persian cavalry—their deadliest asset—was being re-embarked on ships for a pincer movement. This fleeting window of vulnerability, created by enemy logistics, was the key to success.

The Romans often propagandized the concept of 'Punica Fides' or 'Punic Faith' to portray Carthaginians as uniquely treacherous. Yet, their greatest general, Scipio, used blatant deception by feigning peace negotiations with Sifax and Hasdrubal specifically to learn the layout of their camps before burning them down, highlighting the hypocrisy of wartime rhetoric.

Scipio learned that a lagoon protecting New Carthage periodically became shallow. He timed his attack for this moment, presenting the ebbing water to his troops as a miracle promised by the god Neptune. This divine framing inspired his men and enabled a surprise attack on an unguarded wall.

Faced with a longer Persian line, Athenian general Miltiades deliberately weakened his center. This risky move let him match the enemy's length, envelop their flanks, and then turn inwards to crush the stronger Persian center. He turned a numerical disadvantage into a decisive tactical trap.

New military technologies like iron weapons or hoplite shields didn't instantly revolutionize ancient warfare. Their impact was gradual and contingent on broader societal developments, such as increased wealth and larger cities, which enabled their widespread use in new tactical formations.

The historian Polybius described the Roman sack of New Carthage, noting the practice of killing indiscriminately—including cutting dogs in half—was a deliberate policy. This was not random brutality but a calculated psychological tactic to inspire terror and ensure swift surrenders in future conflicts.

Modern retellings often insert motives like controlling trade routes for the Trojan War. However, ancient sources are unanimous that the war was fought solely to recover Helen. This rationalization reflects modern geopolitical thinking, not the values and beliefs of the ancient world.
