Gerin
A Frankish count and companion of Gerer.
The name of his horse was Sorel, and he carried a red shield.
Gerin drove his spear into the body of Malprimis of Brigal.
Grandonie, a son of King Capuel of Cappadocia, was Gerin's slayer. Grandonie also killed Gerin's companion, Gerer, as well as Berenger, another peer. Roland avenged Gerin's death by killing Grandonie.
According to Geoffrey of Monmouth in Historia regum Britanniae (1137), and to Geoffrey's adaptors – Wace and Layamon – Gerin of Chartres was the leader of the Twelve Peers who was present in King Arthur's plenary court at the City of Legion. He was the only paladin of the Twelve Peers to be mentioned. He commanded the second division in Arthur's army with Boso of Oxford, when Arthur confronted the Roman army of Lucius Hiberius.
