The Catholic party soon found that Northumberland had used them only as a cat’s-paw to satisfy his ambition; and that where mild Somerset had scourged them with whips, he would scourge them with scorpions. Gardiner and Bonner were made closer prisoners than ever. Princess Mary, who had practically defied Somerset about her Mass, was more sternly dealt with by Northumberland, her chaplains imprisoned, and her household placed under strict observation;[27] Latin service was strictly forbidden throughout the realm, altars were abolished, and uniformity enforced; whilst Southampton, who had been largely instrumental in the overthrow of Somerset, found, to his dismay, that he had laboured in vain so far as he and his co-religionists were concerned. There is no reason to doubt that, even thus early, Northumberland’s ambitious plans were already formed. For their success two things were absolutely necessary: first, the unanimous support of the Protestant party; and next, a close understanding with France, which meant a reversal of the traditional foreign policy of this country. The attempt to supersede Mary on the death of the King, who was seen to be of short life, would be certain to meet with opposition on the part of the Emperor, and would necessitate the support of France to be successful. Much as Northumberland had denounced the idea of the surrender of Boulogne in the time of Somerset, he lost no time in concluding a peace by which the town was given up, the necessity for doing so being still laid to the charge of his predecessor; and the alliance between France and England, which included Scotland, was nominally made the closer by the betrothal of Elizabeth,[28] the eldest daughter of the King of France to Edward VI. Soon Somerset, who still had many friends amongst Protestants, was released from prison, and in more humble guise readmitted to the Council. On every hand Northumberland courted popularity from all but the extreme Catholics, from whom he had nothing but opposition to expect.
