Sir Adrian Fortescue was well favored by King Henry VIII whom he faithfully served under arms. He was additionally honoured by his own cousin, Anne Boleyn, he was present when she was crowned as Queen in 1533. But Adrian held close and never lost sight of the Honour of God.
In 1539 he was attainted of High Treason without trial, by an Act of Parliament. Sir Adrian Fortescue was beheaded on Tower Hill, London on Wednesday 9 July 1539.
The Order of St. John of Jerusalem has considered Sir Adrian as a martyr and has promoted devotion to him at least since the early seventeenth century as a member of the Order. Pope Leo XIII declared him Blessed on 13 May 1895. His Book of Hours with his Maxims is extant and was recently presented to the Grand Priory of the order of St. John of England (aka, The Order of Malta) by his descendants.
