Layer, who does not seem to have been acting with Atterbury and the Junta until later, was in Rome in the early months of 1721, and there he unfolded his plan to the Jacobite Court. After he left, a plan of campaign was arranged which, however, seems to have been modified afterwards. The original intention was to begin the movement in Scotland, whither Lord Mar and General Dillon[12] were to proceed; and to accentuate the latter’s position as commander in Scotland he was created an earl in the Scottish peerage, although already an Irish (Jacobite) viscount. Lord Lansdowne was to command in Cornwall, Lord Strafford in the north, Lord North in London and Westminster, and Lord Arran was to go to Ireland. The Chevalier was to leave Rome when Mar and Dillon left Paris, and to make his way to Rotterdam _via_ Frankfort, and there await events before deciding where it would be best to land. Things seemed to be prospering, but the English Jacobites did not sufficiently respond to the call for financial support. James, deeply disappointed, appealed to the Pope for help, only to be more bitterly mortified by his refusal. The Pope, in so many words, said that if the English Jacobites wanted a revolution they must pay for it themselves. The original orders for invasion were cancelled in April; but negotiations seem to have been continued with Spain through Cardinal Acquiviva, Spanish envoy at Rome, ever James’s friend. A revised plan of action was prepared. Wogan, who had been sent to Spain, had succeeded in procuring assistance from that country; ships had been prepared to carry a force of 5000 or 6000 men to Porto Longone, in the Isle of Elba, where James was to embark. In July, James was on the outlook for a Spanish fleet under Admiral Sorano.[13] But it was too late. The plot had been discovered, the demand for troops reaching the knowledge of the French ministers, who informed the British ambassador. Spain was compelled to prevent the embarkation, and King George did not go to Hanover that summer.
