Nevertheless, during the five years of life and power which yet remained to him, Richelieu, as far as we know, never again employed the young Master of Requests. But Mazarin, having become first Minister, sent him, in 1647, to the Army of the North, which was under the command of Gassion and Rantzau. The leaders' disagreements were arresting the army's progress. Rantzau was a drunkard whom Gassion could not tolerate. Gassion, sober, energetic and fearless, displayed a brutality insufferable even in a soldier of fortune. He forgot himself so far as to strike in the face a captain of Condé's regiment who had misunderstood his orders. The whole regiment determined to withdraw and the officers struck their tents. Only with great difficulty were they persuaded to remain. Touching this incident, Foucquet wrote to Mazarin: "All are agreed that M. le Maréchal de Gassion committed a serious abuse in striking the captain of His Royal Highness's regiment. Every one condemned such an action, considering that M. le Maréchal should have sent him to prison, or should even have struck him with his sword, or fired his pistol at him, if he thought it necessary; but that it would have been better not to have resorted to such an extreme measure." We ought not, I think, to pass over a fact which permitted Foucquet to display, for the first time, as far as we are aware, that spirit of moderation which, until his reason became clouded, enabled him for a time to serve the State so well. Mazarin was not slow to discern the Intendant's merits. In 1648, at the time of the first disturbances,[6] thinking to quit Paris and withdraw with the Court to Saint-Germain, he sent Foucquet to Brie "with orders there to collect large stores of grain for the maintenance of the army."[7] The Intendant established himself at Lagny and commandeered supplies from the peasants of Brie and Ile-de-France. He was then instructed to compile a list of those Parisians who possessed châteaux or country-houses in the suburbs of the city. Promising to preserve these properties from fire and pillage during the war, Mazarin taxed the owners. In reality he mulcted the rich of the money which he needed. When the Fronde was a thing of the past, Foucquet, as procurator of Ile-de-France, accompanied the King into Normandy, Burgundy, Poitou and Guyenne. On his return from this royal progress, he bought, with the Cardinal's approval, the post of Attorney-General in the Paris Parliament. From this office a certain Sieur Méliand retired in Foucquet's favour, "receiving in return Foucquet's office of Master of Requests, estimated by the son of the said Sieur Méliand as being worth more than fifty thousand crowns, plus a sum of one hundred thousand crowns in money."[8]
