Cromwell's end greatly encouraged the Roman Catholic party, and they were still more elated when the king married a lady known to incline towards the old faith. This was Catherine Howard, a cousin of Anne Boleyn and, like her, a niece of the Duke of Norfolk (1540). Henry had been caught by her beauty, and had not discovered that she was a person of abandoned manners, whose amours were known to many persons about the court. Within eighteen months of her marriage, she was detected in misconduct with one of her old lovers, and sent to the block. In her case Henry had much more excuse for his ruthless cruelty than in that of Anne Boleyn; but what kind of wives could a monarch of such manners expect to find? He was undeservedly fortunate in his sixth marriage, with Catherine Parr, the dowager Lady Latimer, whom he wedded a year after Catherine Howard's execution. She was a young widow of twenty-six, a person of piety and discretion, who gave no opportunity of offence to the king, and nursed him faithfully through the infirmities of his later years. For Henry, who had now reached the age of fifty-two, was growing grossly corpulent and developing a complication of diseases which racked him fearfully during the last five years of his life, and partly explain the frantic exhibitions of cruelty to which he often gave way. [Sidenote: =Scottish war.--Battle of Solway Moss.=] The time was a very evil one for England. Not only was the king persecuting Romanist and Protestant indifferently, but he had added external to internal troubles. A war with Scotland had broken out in 1540, and was always keeping the northern frontier unquiet, though the English had the better in the fighting. James V. allied himself to France, and Henry had to keep guard against attacks on the south as well as the north. The victory of Solway Moss (November, 1542) put an end to any danger from Scotland; the news of it killed King James, who left his throne to his infant daughter Mary, the celebrated "Queen of Scots." Her minority gave rise to factious struggles among the Scottish nobles, and Henry, by buying over one party, was able to keep the rest in check. In 1544 a great English army, under the Earl of Hertford, Jane Seymour's brother, laid waste the whole of the Lowlands and burnt Edinburgh, but did not succeed in driving the enemy to sue for peace.
