"As by the death of the late Messire Arnold, in his life Duke of Guelderland, these counties and duchy have lapsed to me, and by the same token the offices of the land have escheated to our disposition, and among others the office of master of the moneys of those countships ... using the rights, etc., escheated to me, and in consideration of the good and agreeable services already rendered and continually rendered by our knight, etc., Olivier de la Marche, having full confidence in his sense, loyalty, probity, and good diligence--for these causes and others we entrust the office of master and overseer of moneys of the land of Guelders to him, with all the rights, duties, and privileges thereto pertaining. In testimony of this we have set our seal to these papers. Done in our city of Nimwegen, August 18, 1473. Thus signed by M. le duc." On the back of this document was written: "To-day, November 3, 1473, Messire Olivier de la Marche ... took the oath of office of master and overseer of the land and duchy of Guelders."[5] The charge of the ducal children, Charles and Philippa, was entrusted to the duke who, in his turn, deputed Margaret of York to supervise their education. In a comparatively brief time agitation in behalf of the disinherited heir ceased, and imperial ratification alone was required to stamp the territory as a legal fraction of the Burgundian domains. Under the circumstances the minor heirs were the emperor's wards, and it was his express duty to look to their interests, but Frederic III. showed no disposition to assert himself as their champion. On the contrary, the embassy that arrived from his court on August 14th was charged with felicitations to his dear friend, Charles of Burgundy, for his acquisition, and with assurances that the requisite investiture into his dignities should be given by his imperial hand at the duke's pleasure.[6] Communication between Frederic and Charles had been intermittently frequent during the past three years, and one subject of their letters was probably a reason why Charles had been willing to abandon a losing game in France to give another bias to his thoughts. He was lured on by the bait of certain prospects, varying in their definite form indeed, but full of promise that he might be enabled, eventually, to confer with Louis XI. from a better vantage ground than his position as first peer of France. The story of these hopes now becomes the story of Charles of Burgundy.
