While Berengar had begun his conquest of the Kingdom of Portugal in the name of the Emirate of Granada, another war was waging throughout Europe, and that was in the heart of France. Because of Austrian interference, they equipped the factions that opposed the French Crown with a fair amount of firearms, thus turning the tides of war.
Under the guise of representatives from the now-defunct Iberian Union, the duchy of Aquitaine, and the Duchy of Burgundy, who were both in open rebellion against King Gilles de Valois, were well equipped to deal with the ongoing war effort.
Despite the collapse of the Iberian Union, Berengar's agents still supplied the enemies of France by claiming to be representatives of Aragon. Thus, the arms trade between Austria and the rebellious French Duchies remained uninterrupted.
