To me he did not seem so great and so victorious on the day he entered La Rochelle as then; and the journeys he made from his house to the arsenal seem to me more glorious for him than those which he made beyond the mountains, and from which he returned with the triumphs of Pignerol and Suza." This was Cardinal Richelieu's distinction, that all his contemporaries, in the same way as Voiture, identified the mishaps and the successes of their country with his own fortunes, and that upon him alone were fixed the eyes of Europe, whether friendly or hostile, when it supported or when it fought against France.
For four years the war was carried on with desperation by land and sea in the Low Countries, in Germany, and in Italy, with alternations of success and reverse.

The actors disappeared one after another from the scene; the emperor, Ferdinand II., had died on the 15th of February, 1637;--the election of his son, Ferdinand III., had not been recognized by France and Sweden; Bernard of Saxe-Weimar succumbed, at thirty-four years of age, on the 15th of July, 1639, after having beaten, in the preceding year, the celebrated John van Weert, whom he sent a prisoner to Paris.
At his death the landgravate of Elsass reverted to France, together with the town of Brisach, which he had won from the Imperialists.
The Duke of Savoy had died in 1637; his widow, Christine of France, daughter of Henry IV., was, so far as her brother's cause in Italy was concerned, but a poor support; but Count d'Harcourt, having succeeded, as head of the army, Cardinal Valette, who died in 1638, had retaken Turin and Casale from the Imperialists in the campaign of 1640; two years later, in the month of June, 1642, the Princes Thomas and Maurice, brothers-in-law of the Duchess Christine, wearied out by the maladdress and haughtiness of the Spaniards, attached themselves definitively to the interests of France, drove out the Spanish garrisons from Nice and Ivrea, in concert with the Duke of Longueville, and retook the fortress of Tortona as well as all Milaness to the south of the Po.

Perpignan, besieged for more than two years past by the king's armies, capitulated at the same moment.

Spain, hard pressed at home by the insurrection of the Catalans and the revolt of Portugal at the same time, both supported by Richelieu, saw Arras fall into the hands of France (August 9, 1640), and the plot contrived with the Duke of Bouillon and the Count of Soissons fail at the battle of La Marfee, where this latter prince was killed on the 16th of July, 1641.

In Germany, Marshal Guebriant and the Swedish general Torstenson, so paralyzed that he had himself carried in a litter to the head of his army, had just won back from the empire Silesia, Moravia, and nearly all Saxony; the chances of war were everywhere favorable to France, a just recompense for the indomitable perseverance of Cardinal Richelieu through good and evil fortune.
