The battle
An English reinforcement army under Sir John Fastolf departed from Paris following the defeat at Orléans.
The French had moved swiftly, capturing three bridges and accepting the English surrender at Beaugency the day before Fastolf’s army arrived. The French, in the belief that they could not overcome a fully prepared English army in open battle, scoured the area in hopes of finding the English unprepared and vulnerable.
The English reconnoitered with remaining defenders at Meung-sur-Loire. The French had taken only the bridge at this location, not the neighboring castle or the town. Retreating defenders from Beaugency joined them. The English excelled at open battles; they took up a position whose exact location is unknown but traditionally believed to be near the tiny village of Patay. Fastolf, John Talbot, 1st Earl of Shrewsbury and Sir Thomas Scales commanded the English.
The standard defensive tactic of the English longbowmen was to drive pointed stakes into the ground near their positions. This prevented cavalry charges and slowed infantry long enough for the longbows to take a decisive toll on the enemy line. However, at Patay the English archers inadvertently disclosed their position to French scouts before their preparations were complete when a lone stag wandered onto a nearby field and the archers raised a hunting cry.
On hearing the news of the English position, about 1,500 men under captains La Hire and Jean Poton de Xaintrailles, composing the heavily armed and armoured cavalry vanguard of the French army, immediately attacked the English. The battle swiftly turned into a massacre, with every Englishman on a horse fleeing while the infantry, mostly composed of longbowmen, were cut down in droves.
Longbowmen were never intended to fight armoured knights unsupported except from prepared positions where the knights could not charge them. For once the French tactic of a large frontal cavalry assault succeeded, with devastating results.
Captain Jean Dagneau captured the famous General John Talbot. After this feat of arms, Dagneau was ennobled in March 1438 by Charles VII, King of France, which is at the origin of the family name of Dagneau de Richecour.
As for the English, Talbot accused Fastolf of deserting his comrades in the face of the enemy, a charge which he pursued vigorously once he negotiated his release from captivity. Fastolf hotly denied the charge and was eventually cleared of the charge by a special chapter of the Order of the Garter.
