"I shall always," he said in a letter to the First President of the Cour des Monnoies, "be grateful for the King's liberality; but it is enough that I was chargeable to you, while I resided in France. I have never done you any service, though I made you an offer of myself. But it would not be proper that I should now live, like an hornet, on the goods of other men. I shall not, however, forget the kindness of so great a king, and the good offices of so many friends." [Sidenote: CHAP. IX. 1621-1634.] It may appear surprising that Prince Frederick of Orange should pertinaciously exclude Grotius from his native country. But ambition listens to nothing that conflicts with its own views. Prince Frederick inherited from his father and brother the wish of becoming the sovereign of the United Provinces. To this, he knew he should always find a zealous and able opponent in Grotius: hence, notwithstanding his great personal regard for Grotius, he always kept him a banished man. Grotius wished to be employed by the Government of England, and Archbishop Laud was sounded upon this subject; but the application was coldly received[034]. Prince Frederick sustained, both in military and civil concerns, the character of the former princes of his family. Under his administration, the affairs of the republic prospered at sea and land. Peter Haim captured the Spanish flotilla, estimated at twelve millions of florins. The Prince took Bois-le duc, Maestricht, and Breda, and reduced the Dutchy of Limburgh. Under his auspices, the celebrated Van Tromp commenced his career of naval glory, by obtaining a complete victory over the Spanish fleet, consisting of seventy men of war. Prince Frederick died in 1658. From the close of his Stadtholderate, we may date the origin of the jealousy entertained, by France and England, of the rising power of the United Provinces. It is to be observed that Prince Frederick was Stadtholder only of the Provinces of Holland, Zealand, Utrecht, Gueldres and Overyssell: Count Ernest Casimir of Nassau was Stadtholder of the provinces of Gröningen, Frizeland, and the county of the Drenta. In 1631, their eldest sons were chosen, in the lifetime of their fathers, their successors in their respective Stadtholderates. This was a great step towards making the Stadtholderate hereditary in their families,--one of the leading objects of their ambitious views. CHAPTER X.
