In the address to the throne Parliament replied to the effect that the proposed marriage was most pleasing to them, as it would tend to strengthen the ancient alliance between the crowns of Great Britain and Denmark, and "thereby add security to the Protestant religion".[23] [23] Presumably the alliance would strengthen the Protestant religion by weakening the influence of Roman Catholic France at Copenhagen. It must be borne in mind that Denmark was then a much larger and more important country than it is now. Norway had not broken away from the union, and Denmark had not been robbed of the Duchies of Schleswig and Holstein by Prussia. On January 18 the King gave a grand ball at St. James's Palace in honour of the double event of his youngest sister's betrothal and Queen Charlotte's birthday. On this occasion the Princess Matilda made her first appearance at court, when she opened the ball by dancing a minuet with her brother, Prince Edward Duke of York. The Princess was then only thirteen and a half years old, but she won the admiration of all the court by her beauty and grace. She was very fair, with hair almost flaxen in hue, pale gold with a gleam of silver in it, large tender blue eyes, an arched nose, a well-shaped mouth (the underlip perhaps a little too full), and a complexion like the wild rose. Her figure was shapely and developed beyond her years, and she carried herself with ease and dignity. The feelings of the Princess Matilda, who was thus betrothed to a Prince whom she had never seen, were not consulted in the slightest degree. The proposed marriage seemed a suitable one; and it was more brilliant than that of her sister, the Princess Augusta; moreover, it would strengthen the political alliance between England and Denmark, and, it was hoped, give England more influence in the Baltic. These considerations were sufficient for her brother, George III., who must be held directly responsible for this marriage. The question of his sister's happiness, or unhappiness, did not enter. The child Princess disliked the idea from the first; her ladies-in-waiting noticed that so far from showing any pleasure at her added dignity she became pensive and melancholy. She was too young to realise all this marriage would mean to her, but she knew that it would involve exile from her native country, and separation from her family, and she grieved much in secret, though afraid to show her unhappiness openly. She gave some hint of her feelings to her aunt, the Princess Amelia, soon after her betrothal.
