The two met again at Uxbridge in October, when Elizabeth had issued a third proclamation against them, and the search was being pressed vigorously. Campion returned to the provinces, and Parsons decided to remain in or near London. He had a bold design of setting up a press and stealthily issuing Catholic books, but it is reasonable to believe that he was now becoming convinced that only a large political action could save the faith in England. He saw much of the Spanish ambassador, Mendoza, even living in the embassy as a servant for a time; and from his conversations with Mendoza we may confidently date that idea of a Spanish invasion of England which was to dominate the remainder of his unfortunate life and cause incalculable mischief. Not only the general rule of his Society, but a most explicit command laid on him by Mercurian when he left Rome, forbade him to meddle with politics, yet he gradually became wholly absorbed in a political and treacherous project, and we may safely date its birth about this time. Somewhere out of London--at East Ham, Simpson conjectures--he set up his press, and infuriated the Council by disseminating books which their advisers pronounced to have been printed in England. Hundreds of arrests were made, the rack was busy at the Tower, and the laws were made more drastic; yet the "howling wolf" (Parsons) and the "wandering vagrant" (Campion), as they were described in a debate in Parliament, continued to evade the zealous officers. Two other Jesuits, Cottam and Bosgrave, who attempted to join them, were arrested at once and put in the Tower; while the Irish Jesuit, O'Donnell, was hanged, drawn, and quartered at Cork. In the early part of 1581 Fathers Holt and Heywood penetrated the Protestant defences and joined Parsons. He sent Holt on to Scotland, to further the political scheme he now cherished, and later had Father Crichton sent on direct to Edinburgh from Rouen. A genial page of Mr. Andrew Lang's _History of Scotland_ (ii. 282) tells how these Jesuits "let the pigs run through the job" in Scotland. The romance of hiding in Holyrood and assisting the great enterprise of the invasion of England seems to have exalted them, and they gave Mary, whom they would rescue, a very poor opinion of their qualities as diplomatists. They made airy promises of armies, to be provided by some foreign power, until at last even Mendoza begged them to confine themselves to the saving of souls and leave State affairs to statesmen. Father Hay, another Scottish Jesuit who joined them, advocated the assassination of the leading Protestant nobles. These Jesuits returned in the course of time to the Continent; Father Ogilvie, in 1615, was the only Catholic who was executed on the ground of religion in Scotland after a formal trial.
