1549 BCP AND DEVONSHIRE UPRISINGS. Cranmer not inactive against them. New Commission against them which was not so active as it might have been, 41. Cases of Michael Thombe and Joan Bocher (42). Discontent of the country (43). Uprisings, caused partly by enclosures and economics, partly by religion, the BCP and loss of the old ceremonies of the ancestors (44). A top-down Reformation on the people and they had had it with the new things. The rising in the West, notably in the Exeter area, someone's ancestral homeland (45). The new BCP used by a priest in Sampford Courtney, Devonshire, but the priest returns to the old Latin services after public pressure. A revolt in Devon and Cornwall (46). Meanwhile, back in London, divisions of the Council, which concealed their real strength: state of affairs (47). Foreign mercenaries hired in great number—Germans, French, Flemish (48). Weakness and arrogance of Somerset (50). Paget remonstrates with Somerset. Activity of Russell, Herbert, and Grey of Wilton. Mission of the Carews to the West, a ministry of pacification. The barns of Crediton turned into places whence the rebels could shoot on the Sheriffs, Justices and royalist forces. Outbreak at St. Mary's Clist, near Exeter. Failure of the Carews. Force and discipline of the insurgents although untrained commoners. They form the siege of Exeter. They set forth their demands in several Articles or sets of Articles. These are answered rather pacifically by the King but more severely by Dr. Cranmer (59). Dr. Cranmer’s severe answer to the Devonshire militants. 

We have questions, particularly, about the compliance of the staff/clergy at Exeter Cathedral on Whitsunday, 1549. We expect they did comply and the uprisings were in hamlets in/around Exeter. ??. Cranmer and Vermigli get tough on the rebels.
