Battle of Poitiers (1356)

The Battle of Poitiers was fought in 1356 between the forces of Edward the Black Prince and King John II of France. The English army defeated the French and captured the king, creating a major political crisis. The battle deepened the instability already caused by war, taxation, and noble rivalry in France.

Poitiers matters because the capture of a king transformed a military defeat into a diplomatic and financial disaster. Ransom, treaty negotiation, and internal unrest followed. The battle also reinforced the reputation of English tactical methods in the mid-fourteenth century.

Poitiers fits naturally beside Bernard Cornwell’s Hundred Years’ War fiction and novels about the Black Prince, French chivalry, and mercenary warfare. It supports stories about ransom, honour, captivity, battlefield reputation, and the way one day’s fighting could destabilise a kingdom.
