In 1506 fortune favoured Henry. Philip sailed from the Netherlands in January to take possession of the throne of Castile: but was driven on to the English shores by stress of weather. The English King received him royally, but while the utmost show of friendliness prevailed, Philip found that he had no alternative to acceptance of Henry's suggestions. Before the King of Castile departed, he had not only entered on a treaty for mutual defence against any aggressor, but had actually delivered over the person of the unhappy Suffolk [Footnote: So Busch. Gairdner is doubtful.] to his sovereign, though under promise that he should not be put to death. The prisoner, however, was committed to the Tower, and though Henry kept his word, he is reported to have advised his son that the promise would not be binding on him. At any rate Suffolk was executed, apparently without further trial, early in the next reign. His brother Richard, known as the "White Rose," who had abetted him, remained abroad, and was ultimately killed in the service of Francis I. at the battle of Pavia in 1525, leaving no children. Philip had hardly departed from England when a new commercial treaty which he had authorised was signed with the Netherlands, terminating the war of tariffs which had again become active in recent years. This treaty, it is not surprising to remark, was so favourable to England that in contradistinction to the older _Intercursus Magnus_ the Flemings entitled it the _Intercursus Malus_. [Sidenote: Death of Philip] The few remaining months of Philip's life were troubled. The position in Castile was difficult enough, and in his absence the Duke of Gueldres again revolted, with some assistance from France. Henry interfered, as he was bound to do by the recent treaty, not without some effect. But Philip's death in September left his wife Joanna Queen of Castile, with her father Ferdinand as Regent, and her young son Charles Lord of the Netherlands, with Margaret of Savoy at the head of the Council of Regency. Under these new conditions Henry agreed to modifications in the new commercial treaty, which indeed, as it stood, was almost impossible of fulfilment; probably in the hope that his project of marriage with Margaret of Savoy might still be carried out, the dowry she would bring being very much more satisfactory than that of Joanna of Naples.
