- Switched sides and joined Enrique of Trastámara, the future Enrique II of Castile. [Pedro, ch. 25: 44-45]
- Companion of Fernando of Aragon, Count of Tortosa. Was killed in 1363 on the same occasion that the Count of Tortosa was also killed on resisting arrest by order of his half-brother, Pedro IV of Aragon. This was in response to Pedro of Castile's persistent persecution of Enrique de Trastámara's followers and demands that they be handed over to him. [Pedro, ch. 34: 79-82]
