Upon this, Rupert resigned his office of Master of the Horse--a mere empty title--and departed for Germany, notwithstanding Henrietta's entreaties that he would remain.[40] He had hardly declared his intention of going, when the good-natured Charles half-repented of his share in the quarrel; and a reconciliation was accomplished, so far as the debt was concerned.[41] But Rupert adhered to his resolution of visiting Germany, saying that he had affairs of his own to look after, to obtain some appanage from his brother, and to demand the money due to him from the Emperor, under the treaty of Munster. Charles therefore wrote an apologetic letter to his aunt, the Queen of Bohemia, explaining that his cousin had not quitted his service, and that, though he did not deny having "taken some things unkindly" from Rupert, he trusted that they might soon meet again, "with more kindness and a better understanding," for, in spite of all that had passed, he continued to "love him very much, and always be confident of his friendship."[42] Rupert went first to his brother at Heidelberg, with "a great train and brave," consisting of twenty-six persons,--three negroes and "the little nigger" included.[43] At Heidelberg he remained for about a month, but his real destination was Vienna, whither he went to demand the money {277} owed him by the Emperor. He arrived there in September, and was received with great cordiality. He had been a _persona grata_ to the Austrians ever since he had won their hearts as their prisoner; and Cromwell's spies commented, in great disgust, on the honour shown him, and the alacrity with which dues were promised to him. "His Imperial Majesty hath commanded an assignation to Prince Rupert Palatine of 30,000 rix dollars, of a certain sum due since the Treaty of Munster. Prince Rupert has also obtained money for Charles Stuart, and more is promised," they reported.[44]
