This Prince was clever enough to get round the Regent, to impress the Ministers, and to make friends with another of the Princess's uncles, the Duke of Kent. Through the Duke he was able to communicate privately with the Princess, who now declared that he was necessary to her happiness. When, after Waterloo, he was in Paris, the Duke's aide-de-camp carried letters backwards and forwards across the Channel. In January 1816 he was invited to England, and in May the marriage took place. The character of Prince Leopold contrasted strangely with that of his wife. The younger son of a German princeling, he was at this time twenty-six years of age; he had served with distinction in the war against Napoleon; he had shown considerable diplomatic skill at the Congress of Vienna; and he was now to try his hand at the task of taming a tumultuous Princess. Cold and formal in manner, collected in speech, careful in action, he soon dominated the wild, impetuous, generous creature by his side. There was much in her, he found, of which he could not approve. She quizzed, she stamped, she roared with laughter; she had very little of that self-command which is especially required of princes; her manners were abominable. Of the latter he was a good judge, having moved, as he himself explained to his niece many years later, in the best society of Europe, being in fact "what is called in French de la fleur des pois." There was continual friction, but every scene ended in the same way. Standing before him like a rebellious boy in petticoats, her body pushed forward, her hands behind her back, with flaming cheeks and sparkling eyes, she would declare at last that she was ready to do whatever he wanted. "If you wish it, I will do it," she would say. "I want nothing for myself," he invariably answered; "When I press something on you, it is from a conviction that it is for your interest and for your good."
