The Battle of Poitiers (1356) showed how disciplined defensive tactics could defeat even a vastly superior cavalry force. The Black Prince positioned English archers and dismounted knights behind natural obstacles. French cavalry repeatedly charged uphill but were slowed by hedges, ditches, and mud. As momentum stalled, English longbow volleys shattered their formations. When the French king was captured, Poitiers became one of England’s greatest victories of the Hundred Years’ War. #Poitiers135
