It is here seen that not Rupert's private affairs alone had taken him to Vienna, nor was his separation from Charles of long duration. France had now concluded a treaty with Cromwell, so that the exiled King was forced to quit that country. The money obtained through Rupert enabled him to leave France with ease, and he proceeded to Cologne. A rumour arose that he intended to throw himself upon the hospitality of the Emperor, and perhaps Rupert's visit to Vienna had been partly designed to ascertain the possibility of this move. But the idea did not commend itself to the Austrian Court, and the Elector Charles Louis wrote hastily to Rupert, October 1654: "I have ventured to send M. Bunckley to the King of Great Britain, to warn him that he would be unwelcome at Vienna. Doubtless you will be able to confirm this, concerning which I have received an express messenger from his Imperial Majesty."[45] Probably Rupert did confirm his brother's message, for Charles stayed at Cologne, awaiting his cousin's "much longed for" return. Rupert rejoined him there in January 1655, but did not stay long. Hyde was still all powerful, and Rupert was never a man who cared to take the second place. "I need not tell you," wrote one of the ubiquitous spies, "by whom Prince Rupert was turned from Court; yet perhaps you {278} have not known that Hyde offered Charles Stuart that 50,000 men should be in arms in England, before a year went about, if he would quit the Queen's Court, and the Prince's party. By the last letters it doth seem as if Prince Rupert had an intention to see Cologne before Modena, and, if he can break Hyde's neck here, it may alter his design, and make him stay with the King, which he hath most mind of."[46]
