Philip (_le Hardi_) can hardly have had any heart in the enterprise which was forced upon him by the Pope. His eldest son, who had a strong feeling of regard and admiration for his uncle En Pedro, openly disapproved. When his younger brother, Charles of Valois, talked of himself as King of Aragon, Philip said to him: ‘You, little brother, are not fit to take the place of our uncle. You are scarcely fit to be king of what is under your cap. You will never be King of Aragon.’ There was an angry quarrel, and their father had to separate them. But Charles got the name of King Cap, ‘_le roi du chapeau_.’ Nevertheless, it was generally believed that little Aragon would have no chance against the whole power of France, and that the campaign could have but one result, and would be over in a few weeks. The oriflamme was unfurled, and a great army, led by the King of France and accompanied by the Cardinal Legate, advanced to the Catalonian frontier. A formidable fleet was also equipped, to overpower the naval forces of Aragon and to keep up the supplies for the army in the bay of Rosas. In April 1285 King Philip encamped with his army at Perpignan. The French were constantly harassed by night attacks from the Aragonese; and at last, after a fortnight of hesitation, Philip determined to attempt a passage into Catalonia by the hill of Panisars. Here he was attacked on all sides, suffering very serious losses. Then young Philip turned to his brother and said: ‘See now, pretty brother, how glad your subjects are to see you!’ His father overheard the sneer and was very angry. ‘Hold your tongue, Philip. They will be made to repent what they are doing.’ ‘Ah, Sire,’ answered his son, ‘I mourn for your honour and for the evil that is being done you. The Pope and cardinals have brought this upon you, and have made my brother king of the wind, while they take their pleasure, caring little for the danger and evil with which you are menaced.’ The King was silent, for he knew very well that his son had merely spoken the truth. But it was too late to repent and turn back. Following the advice of some monks, Philip got possession of another pass, known as the ‘Collado de Masona,’ and his army was thus enabled to invade Catalonia. The little town of Peralada was taken after a brave resistance, and siege was laid to the city of Gerona. But the French army was harassed by incessant attacks, and was entirely dependent for supplies on the navy which guarded the transports conveying provisions from Marseilles and Cette to the bay of Rosas. Here was the weak point.
