Oliver

A Frankish count and a companion of Roland. Oliver was a son of Renier, Lord of the Vale of Runers, and brother of Aude.

Halteclere was the name of his sword. In Chanson de Roland, he was a contrast to the reckless boldness of Roland with his more prudent and wisdom.

Among the warriors he slew was Justin of Val Ferree. Oliver also avenged the death of Engeler by killing Climborin.

It was Marganice who delivered the fatal blow to Oliver, stabbing his lance from behind at Oliver's back. But he killed Marganice with Halteclere.
