After Cannae, Rome couldn't defeat Hannibal in open battle, so they adopted a strategy of avoidance, creating a stalemate. For a power on the brink of collapse, simply surviving is a form of victory. This prolonged timeline allowed Rome to regroup, rebuild its manpower, and ultimately go on the offensive.

Rome's political and cultural identity was built on an implacable resolve to never accept defeat or disrespect. This dogged determination, which led them to build a navy from scratch and reject peace talks after catastrophic losses, was their ultimate strategic advantage over more conventional powers.

Showing mercy to disabled enemy combatants is tactically superior for three reasons: it encourages adversaries to surrender rather than fight to the death; it yields valuable intelligence from prisoners; and it establishes a standard of conduct that protects one's own captured soldiers from reciprocal brutality.

After losing Sicily, the Carthaginian general Hamilcar Barca and his son Hannibal didn't try to reclaim it directly. Instead, they built a new, resource-rich empire in Spain. Its vast mineral wealth funded a mercenary army, turning Spain into a formidable base from which to launch a revenge war against Rome.

Openness is a tool for dominance, not just a moral virtue. The Romans became powerful by being strategically tolerant, quickly abandoning their own methods when they found better ones elsewhere. This allowed them to constantly upgrade their military, technology, and knowledge from conquered peoples.

In a conflict, the person who has been wronged and is in a position to forgive holds the ultimate power. Responding to aggression with aggression creates a stalemate. Choosing forgiveness disrupts the opponent's framework, cancels their perceived debt, and creates an opening for radical change.

The harsh terms of the First Punic War, which stripped Carthage of territory and imposed a massive indemnity, created deep resentment. This parallels the Treaty of Versailles with Germany, illustrating how overly punitive settlements can sow the seeds of a future war of revenge rather than secure lasting peace.

After his decisive victory at Cannae, Hannibal expected Rome to negotiate terms, as was the norm in ancient warfare. He fatally underestimated their unique, implacable resolve to never capitulate, causing him to miss his window of opportunity to march on the city and enforce a peace.

Joan's dictated letter to the English was not a negotiation but a divine ultimatum. By positioning herself as a "captain of war" sent by the "King of Heaven," she reframed the political conflict as a holy war, a powerful psychological tactic designed to demoralize her opponents by presenting her victory as inevitable.
