[4] On 25 January, a new French army of 25,000 infantry and 4,000 cavalry under command of Charles de La Porte, 1st Duke of La Meilleraye, accompanied by King Louis XIII of France and Cardinal Richelieu, left Paris for Roussillon where it arrived on 10 March.

First, Argelès-sur-Mer was retaken and on 11 April, the Château Royal de Collioure, bravely defended by 3,400 men under command of the Marquis of Mortara, was also conquered after a siege of 4 weeks.

[5] La Meilleraye now surrounded Perpignan with his entire army and waited for the famine to force the Spanish into surrender.

The governor, the Marquis de Flores Dávila, was forced to surrender the city on 9 September 1642, because of the increasing number of casualties by hunger, and because the Spanish garrison had been reduced to only 500 able-bodied men.

[7] After the fall of Perpignan, the Fort de Salses remained completely isolated without any hope of relief, and therefore also surrendered.
