Garnet was at Coughton Court on 6 November when Thomas Bates brought news of the plot's failure. Catesby wanted him to help raise support in Wales, where it was thought Catholic support would be more likely, but Garnet was horrified. In a letter to Catesby and Digby, he urged them to abandon their "wicked actions" and follow the pope's advice. He spent weeks on the run but was eventually arrested on 27 January 1606, at Hindlip Hall. There, for eight days, he and Fr. Edward Oldcorne (later beatified as the Blessed Edward Oldcorne) had secreted themselves in a small, cramped space, unable even to stand or stretch their legs. They received sustenance from their protectors through a small drinking straw hidden within the building's structure, but with no commode or drainage they were eventually forced by "customs of nature which must of necessity be done" to emerge from hiding, and were immediately captured. They were taken first to Holt Castle in Worcestershire, and a few days later to London. Garnet was still weak from his ordeal, and Salisbury therefore ordered that he be given a good mount; his supplies were paid for by the king. The group was accompanied by a Puritan minister who "ranted at length without interruption", but Garnet's replies remained erudite, brief and clear—much to the minister's disappointment. On his arrival in London he was taken to the Gatehouse Prison in Westminster, which was already home to many Catholic prisoners, including his nephew, Father Thomas Garnet.
