Rescue and repatriation of bodies. Nothing would be known about the matter were it not for the discovery, in the National Library of Paris, of the epitaph of one of the dead figures. It is unknown, therefore, where Eggihard was buried; his body was rescued and repatriated to France, either on the day of the battle or through subsequent arrangements. Everything seems to confirm the idea that Charles was personally involved in the battle, managing to save his vanguard at the expense of his rearguard. The repatriation of the bodies of his vassals was a sacred matter at that time and even in later centuries. Charles must have returned to the scene of the defeat, most likely the next day, during daylight hours, to rescue the bodies of the most notable figures. This presence of Charles is attested by what the sources say, stating that he was unable to take revenge for the defeat given the dispersion of the Basques.
