The Earl of Bothwell was a man of great energy of character, fearless and decided in all that he undertook, and sometimes perfectly reckless and uncontrollable. He was in Scotland at the time of Mary's return from France, but he was so turbulent and unmanageable that he was at one time sent into banishment. He was, however, afterward recalled, and again intrusted with power. He entered ardently into Mary's service in her contest with the murderers of Rizzio. He assisted her in raising an army after her flight, and in conquering Morton, Ruthven, and the rest, and driving them out of the country. Mary soon began to look upon him as, notwithstanding his roughness, her best and most efficient friend. As a reward for these services, she granted him a castle, situated in a romantic position on the eastern coast of Scotland. It was called the Castle of Dunbar. It was on a stormy promontory, overlooking the German Ocean: a very appropriate retreat and fastness for such a man of iron as he. In those days, the border country between England and Scotland was the resort of robbers, freebooters, and outlaws from both lands. If pursued by one government, they could retreat across the line and be safe. Incursions, too, were continually made across this frontier by the people of either side, to plunder or to destroy whatever property was within reach. Thus the country became a region of violence and bloodshed which all men of peace and quietness were glad to shun. They left it to the possession of men who could find pleasure in such scenes of violence and blood. When Queen Mary had got quietly settled in her government, after the overthrow of the murderers of Rizzio, as she thus no longer needed Bothwell's immediate aid, she sent him to this border country to see if he could enforce some sort of order among its lawless population. The birth of Mary's son was an event of the greatest importance, not only to her personally, but in respect to the political prospects of the two great kingdoms, for in this infant were combined the claims of succession to both the Scotch and English crowns. The whole world knew that if Elizabeth should die without leaving a direct heir, this child would become the monarch both of England and Scotland, and, as such, one of the greatest personages in Europe. His birth, therefore, was a great event, and it was celebrated in Scotland with universal rejoicings. The tidings of it spread, as news of great public interest, all over Europe. Even Elizabeth pretended to be pleased, and sent messages of congratulation to Mary. But every one thought that they could see in her air and manner, when she received the intelligence, obvious traces of mortification and chagrin.
