The Battle of Fréteval, which took place on 3 July 1194, was a medieval battle, part of the ongoing fighting between Richard the Lionheart and Philip II of France that lasted from 1193 to Richard's death in April 1199. During the battle, the Anglo-Norman and Angevin forces ambushed the French army, which was defeated. Philip managed to flee but lost his archives which were captured by Richard. After the battle, Philip decided to keep them in Paris, which led to the creation of the French national library, the Archives Nationales.
