Tartas
Tartas stands on the Midouze, a tributary of the Adour, in the lands once held by the lords of Albret. During the Hundred Years' War an English army besieged the town in 1440. Its defenders agreed to surrender unless relieved by a fixed date, and in 1442 Charles VII marched south with the dauphin to secure it. The expedition, remembered as the Voyage of Tartas, became part of the French advance into Gascony.
