My namesake, St. Edmund Campion, was a Jesuit priest who was hung, drawn, and quartered under Queen Elizabeth under a charge of "high treason". His "treason" consisted in saying Mass and hearing confessions.
Evelyn Waugh wrote a very fine biography of St. Edmund; it's available through Sophia Press.
BTW, do any of your sources mention that Tyndale was "fingered" to the ecclesiastical courts in Belgium by an agent of the (Protestant) King Henry VIII?

His crime, however, wa refusing to confess to a priest. Seems there really were Spanish Protestants.
