From 1669 until his death, Walsh lived in London, much respected for his honesty, loyalty and learning. Through the influence of Ormonde, he secured the seneschalship of Winchester (worth about £100 a year) from the bishop of that see. He and his supporters were declared renegades to be spurned by other friars by the Order's General Chapter of 1670 for having published without the permission of the Minister General of the Order, but he remained a devout adherent of the Catholic Church, although he maintained friendly relations with the Anglicans, accepting their Holy orders and attending their churches. It is said that it was only a few days before his death, he was induced to make his peace with the Church, though that has been questioned. At his death, his books and papers were removed by the friars. He was buried in the churchyard of the Church of St Dunstan-in-the-West.
