Афонсу IV
In 1336 the Castilian-Leonese troops, among which were those of Pedro Ponce de León, together with those of Juan Alonso Pérez de Guzmán y Coronel, second lord of Sanlúcar de Barrameda, and commanded by Enrique Enríquez the Younger, lord of Villalba de los Barros, defeated the troops of King Afonso IV of Portugal in the Battle of Villanueva de Barcarrota. This victory forced the king of Portugal to lift the siege of Badajoz.
