Poitiers (Hundred Years' War).
Fought September 19, 1356, between 8,000 English, under Edward the Black Prince, and 80,000 French, under King John of France. The English occupied a strong position behind lanes and vineyards, in which their archers were posted. The French cavalry, charging up the lanes, were thrown into confusion by the bowmen, and were then taken in flank by the English knights and men-at-arms, who completely routed them, with a loss of 8,000 killed, and numerous prisoners, including the King. The English losses were very small.
