When the Glorious Revolution began, Sabran was responsible for getting the prince out of the country. They headed for Portsmouth, but he was then ordered to return to London before being allowed to escape. He disguised himself as an attendant to a group of Polish nobles but was discovered by a crowd and beaten and imprisoned. He was freed from prison, however, by order of the king. Sherlock coincidentally issued a reply to Sabran as the revolution was starting, entitled "A Vindication: an Answer to the Cavils of Lewis Sabran".
