Henry V has claimed the French crown for his heirs, but holding it means conquering the whole of France, and the resistance that finally stops the English advance comes from an unlikely source: Joan of Arc, an illiterate peasant girl from Domremy who says she hears voices from God. Historian Dr Janina Ramirez traces how Joan talks her way into the French court, convinces Charles VII's advisors of her mission, and leads troops to break the siege of Orleans, turning the war's momentum after decades of English victories. The episode sits within a longer account of the conflict Ramirez calls the longest and bloodiest divorce in history, using battlefield sites, period sources, and expert testimony to explain how a peasant girl with no military training ends up commanding armies. It covers the political maneuvering around Charles VII's coronation at Reims and the suspicion Joan's success provokes among the same nobles she has just saved, setting up the reversal that follows. The focus stays on documented events and their consequences rather than legend.
