Henry VIII succeeded to the throne of England in April, 1509; three years and five months later, in September, 1513, was fought the battle of Flodden. The causes may soon be told. They fall under three heads. James and Henry were alike headstrong and impetuous, and they were alike ambitious of playing a considerable part in European affairs. They were, moreover, brothers-in-law, and, in the division of the inheritance of Henry VII, the King of England had, with characteristic Tudor avarice, retained jewels and other property which had been left to his sister, the Queen of Scots. In the second place, the ancient jealousies were again roused by disputes on the borders, and by naval warfare. James had long been engaged in "the building of a fleet for the protection of our shores"; in 1511, he had built the _Great Michael_, for which, it was said, the woods of Fife had been wasted. The Scottish fleet was frequently involved in quarrels with Henry's ships, and in August, 1511, the English took two Scottish vessels, which they alleged to be pirates, and Andrew Barton was slain in the fighting. James demanded redress, but, says Hall, "the King of England wrote with brotherly salutations to the King of Scots of the robberies and evil doings of Andrew Barton; and that it became not one prince to lay a breach of a league to another prince, in doing justice upon a pirate or thief".[60] These personal irritations and petty troubles might have proved harmless, and, had no European complications intervened, it is possible that there might have "from Fate's dark book a leaf been torn", the leaf which tells of Flodden Field. But, in 1511, Julius II formed the Holy League against France, and by the end of the year it included Spain, Austria, and England. The formation of a united Europe against the ancient ally of Scotland thoroughly alarmed James. It was true that, at the moment, England was willing to be friendly; but, should France be subdued, whither might Scotland look for help in the future? James used every effort to prevent the League from carrying out their project; he attempted to form a coalition of Denmark, France, and Scotland, and wrote to his uncle, the King of Denmark, urging him to declare for the Most Christian King. He wrote Henry offering to "pardon all the damage done to us and our kingdom, the capture of our merchant ships, the slaughter and imprisonment of our subjects", if only Henry would "maintain the universal concord of the Church". He made a vigorous appeal to the pope himself, beseeching him to keep the peace. His efforts were, of course, futile, nor was France in such extreme danger as he supposed. But the chance of proving himself the saviour of France appealed strongly to him, and, when there came to him, in the spring of 1513, a message from the Queen of France, couched in the bygone language of chivalry, and urging him, as her knight, to break a lance for her on English soil, James could no longer hesitate.
