administered by the viscounts of Béarn, who had become titular Kings of Navarre.
Tarbes was fortified in the tenth century by Raymond I. It suffered destruction at the hands of the English in 1350 and 1406. But its greatest disasters took place during the Wars of Religion. Jeanne d'Albret was resolved on forcing the Reform on the Bigorriens, but they ejected the Huguenot pastors as fast as they were sent to them, and appealed to the King of France, who sent troops in 1569 to their aid. Jeanne enlisted the services of Montgomery. He swept through the country, ravaging it with fire and sword. He sent his lieutenant, Montamat, to take Tarbes, and Montamat appeared under its walls on 20 January, 1570. The besieged, finding it impossible to hold out, evacuated the city during the night. When the Huguenots entered they found no one in the place, and they pillaged the houses and set them on fire.
When he was gone the inhabitants returned and began to restore their wrecked and gutted houses and to repair the walls. Montamat reappeared, bringing cannons with him. François de Bennasse, commandant of the garrison at Lourdes, had hastened to the defence of the capital at the head of 800 men. Montamat attempted an assault, and was repulsed. But a traitor in the town opened the gates to the Calvinists, and the captain entered. Bonnasse, all his soldiers, and many of the citizens were put to the sword. The number massacred was so great that it took eight days to bury them.
