Second battle of olmedo
The Second Battle of Olmedo was fought on 20 August 1467 near Olmedo in Castile (now in the province of Valladolid, Spain) as part of the succession conflict between Henry IV of Castile and his half-brother Alfonso, Prince of Asturias.
Alfonso's troops advanced eastwards along the valley of the Duero towards central Castile, while the troops loyal to Henry moved north from Cuéllar towards Medina del Campo to try to cut them off: the two armies met near Olmedo.
Henry's troops comprised:
A notable absence among Henry's troops was Juan Pacheco, who was occupied with securing the leadership of the Order of Santiago.
With Prince Alfonso fought the troops of the Archbishop of Toledo, the Archbishop of Seville, of the Counts of Luna, Plasencia and Ribadeo, as well as of the Order of Calatrava.
The result of the battle is not altogether clear, as both sides claimed victory, although Henry's troops were superior in strength. However, after the battle, Henry lost the support of Pedro Arias de Ávila and of the Count of Alba, the latter won over by favours from the Marquess of Villena and from the Archbishop of Toledo.
