At the age of eleven years, William having thus unexpectedly succeeded to such great possessions, was sent from his father’s roof to be educated in Brussels.  No destiny seemed to lie before the young prince but an education at the Emperor’s court, to be followed by military adventures, embassies, viceroyalties, and a life of luxury and magnificence.  At a very early age he came, accordingly, as a page into the Emperor’s family.  Charles recognized, with his customary quickness, the remarkable character of the boy.  At fifteen, William was the intimate, almost confidential friend of the Emperor, who prided himself, above all other gifts, on his power of reading and of using men.  The youth was so constant an attendant upon his imperial chief that even when interviews with the highest personages, and upon the gravest affairs, were taking place, Charles would never suffer him to be considered superfluous or intrusive.  There seemed to be no secrets which the Emperor held too high for the comprehension or discretion of his page.  His perceptive and reflective faculties, naturally of remarkable keenness and depth, thus acquired a precocious and extraordinary development.  He was brought up behind the curtain of that great stage where the world’s dramas were daily enacted.  The machinery and the masks which produced the grand delusions of history had no deceptions for him.  Carefully to observe men’s actions, and silently to ponder upon their motives, was the favorite occupation of the Prince during his apprenticeship at court.  As he advanced to man’s estate, he was selected by the Emperor for the highest duties.  Charles, whose only merit, so far as the provinces were concerned, was in having been born in Ghent, and that by an ignoble accident, was glad to employ this representative of so many great Netherland houses, in the defence of the land.  Before the Prince was twenty-one he was appointed general-in-chief of the army on the French frontier, in the absence of the Duke of Savoy.  The post was coveted by many most distinguished soldiers:  the Counts of Buren, Bossu, Lalaing, Aremberg, Meghem, and particularly by Count Egmont; yet Charles showed his extraordinary confidence in the Prince of Orange, by selecting him for the station, although he had hardly reached maturity, and was moreover absent in France.  The young Prince acquitted himself of his high command in a manner which justified his appointment.

It was the Prince’s shoulder upon which the Emperor leaned at the abdication; the Prince’s hand which bore the imperial insignia of the discrowned monarch to Ferdinand, at Augsburg.  With these duties his relations with Charles were ended, and those with Philip begun.  He was with the army during the hostilities which were soon after resumed in Picardy; he was the secret negotiator of the preliminary arrangement with France, soon afterwards confirmed by the triumphant treaty of April, 1559.  He had conducted these initiatory conferences with the Constable
