In the meantime, there had been a futile insurrection in the North, headed by Sir John Neville, in the Spring of 1541; which led to the execution not only of Neville himself, but of the old Countess of Salisbury--niece of Edward IV., mother of the Poles, and grandchild of the "King-maker". Not long after this, the Norfolk interest suffered a severe shock at Henry's court from the discovery of flagrant and confessed misconduct on the part of the monarch's fifth spouse, Katharine Howard; she was attainted and beheaded, in February, 1542, and succeeded by Katharine Parr; who was fortunate enough to outlive her husband. [Sidenote: 1543 Henry's Scottish policy] Solway Moss inspired Henry with a fresh determination to invade and chastise Scotland; but James's death suggested a simpler method. For the moment, Beton was in the hands of his enemies. Henry proposed that the baby Mary should be betrothed to his own son Edward, that the government of Scotland should be vested in a Council which he could control, and that sundry English garrisons should be planted in the country. The Scots lords captured at Solway Moss were quite ready to promise support to his plans as the price of returning home: they were also ready to break faith with the English King when they got there; and did so. As soon as the lords were out of Henry's reach, the Scots Estates demanded modifications in the proposed treaty which would have made it nugatory from the English point of view. A Scottish Prince might have been allowed to wed an English Princess; but Scotland would not take her King from England. It was not long before the Cardinal recovered his ascendancy, and, acting in conjunction with the queen-mother, Mary of Guise, sought the aid and alliance of France. [Sidenote: Alliance with Charles] The French King was already at war with Charles, and his relations with England were exceedingly strained; whilst he was openly declaring his determination to support Scotland, and French ships were playing the pirate in the Channel. The Emperor on the other hand had quieted the Protestant league by his tolerant attitude at the Diet of Ratisbon (1541); but the Duke of Cleves, Henry's enemy, was defying him. Hence the whole conditions pointed to an anti-French _rapprochement_ between Charles and Henry; which took the form of a treaty of alliance early in 1543. If the territories of either Power were invaded, the other was to render assistance: and thereafter neither was to make peace unless his ally was satisfied also. The French King attempted to detach England by offering to meet the bulk of her separate requirements; and considering the prevailing standard of bad faith, it is to Henry's credit that he refused these overtures.
