How a rainy afternoon in 1346 permanently changed the landscape of Western European warfare.
At the Battle of Crécy, a smaller English force dismantled a vastly superior French army. By leveraging the longbow and a carefully chosen defensive position, Edward III neutralized the pride of French chivalry, proving that traditional mounted knights were no longer the undisputed masters of the medieval battlefield.
On 26 August 1346, the Hundred Years' War reached a pivotal moment near Crécy-en-Ponthieu. King Edward III, having marched his English army through northern France, occupied a strategic hillside. His force, estimated by modern historians at between 7,000 and 15,000, faced a French host commanded by King Philip VI that was at least twice, and perhaps three times, as large. The English were rested and well-positioned, while the French arrived exhausted after a long march.
The battle began with a failed archery duel. Genoese crossbowmen, lacking their protective pavises and hampered by rain-slicked mud, were quickly routed by English and Welsh longbowmen. The French knights, viewing the retreating mercenaries as traitors, rode them down, creating chaos. This disorder, combined with the uphill terrain, defensive pits, and the relentless, high-volume fire of the longbows, shattered the French cavalry charges. The English men-at-arms, fighting on foot, held firm against the disorganized, momentum-less assaults.
Crécy marked the rise of the longbow as a dominant tactical force. Capable of firing up to ten arrows per minute at ranges exceeding 300 metres, the weapon proved lethal even against plate armour. The English also deployed early gunpowder weapons, including ribauldequins and bombards. This victory crippled French efforts to relieve the siege of Calais, which fell the following year and remained under English control for over two centuries, until 1558.
The engagement is often cited as a turning point where the tactical superiority of heavy cavalry was eclipsed by disciplined infantry and missile troops. While contemporary chroniclers provided wildly exaggerated figures for the French army—some claiming up to 120,000 men—modern analysis suggests a more realistic, though still overwhelming, force. The battle remains a definitive study in how terrain, preparation, and technological adaptation can overcome sheer numerical advantage.
