In 1285, Philip entrenched himself before Girona in an attempt to besiege it. Despite a strong resistance the city was taken. Charles was crowned there, but without an actual crown. The French soon experienced a reversal, however, at the hands of Roger de Lauria, back from the Italian theatre of the drawn-out conflict. The French fleet was defeated and destroyed at the Battle of Les Formigues. Further the French camp was hit hard by an epidemic of dysentery, and Philip himself was afflicted. The heir to the French throne, the king of Navarre, opened negotiations with Peter for free passage for the royal family through the Pyrenees. But the troops were not offered such passage and were devastated at the Battle of the Col de Panissars. The king of France himself died at Perpignan, the capital of James of Majorca, who had fled in fear after being confronted by Peter, and was buried in Narbonne.
