John is noted not only for successfully hiding from the English authorities for eight years before his capture, but for enduring extensive torture, escaping from the Tower of London and, after recovering, continuing with his covert mission. After his escape to the continent, he was later instructed by his Jesuit superiors to write a book about his life (Latin text). An English translation was published in 1951.
Gerard was finally captured in London on 23 April 1594, together with Nicholas Owen. He was tried, found guilty and sent to the Counter in the Poultry. Later he was moved to the Clinkprison where he was able to meet regularly with other persecuted English Catholics. Due to his continuation of this work, he was sent to the Salt Tower in the Tower of London, where he was further questioned and tortured by being repeatedly suspended from chains on the dungeon wall. The main aim of Gerard’s torturers was to identify the London lodgings of Fr. Henry Garnet that they might arrest him. He would not answer any questions that involved others, or name them. He insisted that he never broke, a fact borne out by the files of the Tower.
Henry Garnet wrote about Gerard:
- “Twice he has been hung up by the hands with great cruelty on the part of others and no less patience on his own. The examiners say he is exceedingly obstinate and a great friend either of God or of the devil, for they say they cannot extract a word from his lips, save that, amidst his torments, he speaks the word, ‘Jesus’. Recently they took him to the rack, where the torturers and examiners stood ready for work. But when he entered the place, he at once threw himself on his knees and with a loud voice prayed to God that … he would give him strength and courage to be rent to pieces before he might speak a word that would be injurious to any person or to the divine glory. And seeing him so resolved, they did not torture him.”
A famous exploit of his is believed to have been masterminded by Saint Nicholas Owen. With help from other members of the Catholic underground, Gerard, along with John Arden, escaped on a rope strung across the Tower moat during the night of 4 October 1597. Despite the fact that his hands were still mangled from the tortures he had undergone, he succeeded in climbing down. He even arranged for the escape of his gaoler (jailer), with whom he had become friendly, and who he knew would be held responsible for the jailbreak. Immediately following his escape, he joined Henry Garnet and Robert Catesby in Uxbridge. Later, Gerard moved to the house of Dowager Elizabeth Vaux at Harrowden. From this base of operations, he continued his priestly ministry, and reconciled many to the Catholic Church, including Sir Everard Digby (one of the conspirators in the Gunpowder Plot). He later suspected Digby of plotting something, but did not act, thus allowing the plan to proceed undetected. When the plot was discovered, Gerard was a very wanted man due to his links to those involved.
He was incorrectly implicated by Robert Catesby’s servant Thomas Bates. Staying a while at Harrowden, then escaping from there to London, he left the country with financial aid from Elizabeth Vaux, slipping away disguised as a footman in the train of the Spanish Ambassador on the very day of Henry Garnet’s execution. Gerard went on to continue the work of the Jesuits in Europe, where he wrote his autobiography on the orders of his superiors. He died in 1637, aged 73, at the English College seminary, Rome.
