That list was really good, but they forgot one of the worst defeats for the French- Agincourt.
King Henry the 5th of England got pissed at a remark made by the French Dauphan (sp?) and let a smallish group of knights into Northern France . They wandered around for a while causing trouble, and eventually the French Dauphan assembled a vastly overwhelming force of the creme-de-la-creme of French Knighthood. They confronted the now yet smaller sick and hungry band of English Knights on a field near Agincourt. The French, using all of their vast store of military wiles, decided upon a "decisive" massed charge of heavy cavalry into a swampy low area in front of the English lines. Their horses bogged down in the mud, allowing English Longbowmen to pick them off at leisure from the safety of a treeline.
The English account lists 5,000 French Knights killed for a loss of 15 Englishmen. That number includes a number of of "camp followers" that were in the English rear area, killed by a small group of Dishoniorable Frenchmen.
