Lord Malmesbury did not return immediately to England. At Hanover he received another mark of the confidence of his royal master, in a commission to demand the Princess Caroline of Brunswick in marriage for the Prince of Wales. This mission was conferred upon him directly by the king, and no discretionary power was given to offer information or advice either to the court or the government. It does not appear that the subject was ever mentioned to Lord Malmesbury before his credentials arrived; certain it is that he had no communication with the person most deeply interested in the alliance, and therefore no means of ascertaining his wishes or his motives. The Prince of Wales had never seen his cousin. Probably, beyond the false impression conveyed by a portrait, he knew nothing of her; for the little court of Brunswick was rarely visited by the English, and the military occupations of the Duke kept him almost constantly from home. It must ever be matter of deep regret that more prudence was not employed in the conduct of this unhappy business. Royal marriages are at best precarious; for there is too often a larger ingredient of policy than of affection in the alliance. This one needed not to have been a matter of policy. Neither the illustrious bridegroom, nor the kingdoms over which he was afterwards to rule, could derive any advantage from a more intimate connexion with the diminutive state of Brunswick. It is, therefore, almost incomprehensible that no precautions were taken, and no investigations made, before the prince was finally committed. Surely some one might have been found worthy to play the part of a Buckingham to the successor of Charles--some intimate of the prince, who, acquainted with his tastes and inclinations, might have visited Brunswick as a stranger, and, without betraying the actual nature of his mission, might have acquired a sufficient knowledge of the manners and character of the princess to frame an adequate report. Common prudence should have suggested this; but there is too much reason to fear that the match was the result of motives little creditable to other members of the royal family of England, and was not expected by them to secure the ultimate happiness of either party. This, at least, was the opinion of Lord Malmesbury, a shrewd observer, and well versed in the domestic politics of St James's. He says--"She (the princess) talks about the Duke of Clarence, whom she prefers to the Duke of York, and it struck me to-day, for the first time, that he originally put her into the prince's head; and that with a view to plague the Duke and Duchess of York, whom he hates, and whom the prince no longer likes, well knowing that the Princess Caroline and Duchess of York dislike each other; and that this match would be particularly unpleasant to her and the duke." Again, "Princess Caroline asks about the Duke of Clarence--says she believes he was the person who first mentioned her to the prince.--N.B. My own private ideas and feelings on this remark."
