In 762 Pepin broke the back of the Aquitanian resistance. While the war continued for another six or seven years, after 762 it was clear that it was only a matter of time before the final Frankish victory. The campaigns waged by each side during this pivotal year clearly illustrate both the strategy followed by the Franks, as well as the fatal flaw in the Aquitanian leadership.
The previous year Waifar, or more precisely, a couple of his dukes, had launched an unopposed assault into Burgundy, and returned with much plunder. But then king Pepin marched into eastern Aquitaine and burned several major fortresses. Clearly this was not an equation of exchange which would work out for Waifar in the long run. Waifar must have been pondering his options, none of them good, when Pepin came over the river in force, with a major siege train, heading for the de facto capital of northern Aquitaine.
