Raoul II of Brienne, Count of Eu

[1] He succeeded his father in 1344 as Count of Eu and Guînes, as well as in his post as Constable of France.

[2] In 1340, he married Catherine (d. 1388), the daughter of Louis II, Baron de Vaud.

They had no children; one illegitimate son, Jean du Bois, Lord of la Maison Forte, was legitimized as Raoul's in 1395, although his actual genealogy is disputed.

[4] In 1346, he was captured at Caen during the battle by Thomas Holland, 1st Earl of Kent and kept prisoner.

Upon his arrival, he was seized and summarily executed by decapitation without any due process under orders of John II of France,[7] for reasons that remain unclear, although it was rumoured that he had pledged Thomas his castle and the County of Guînes for his release.
