He wrote an account in French of the war against Holland (1665-67) in which he had served; an English version of his book was published in 1671. Denounced by Titus Oates as a Jesuit he was tried and acquitted, afterwards serving James II. as ambassador to Pope Innocent XI. After James II.'s flight, his Jacobite sympathies caused him to be suspected by the Government, and his time was mainly spent either in prison or in exile. He died at Oswestry on July 21, 1705.
