Lord Mar made Perth his headquarters, and invited James to join the Scottish army. The Chevalier, who had moved to Paris in October, in strict secrecy, and in disguise, being watched by both French and English agents, managed, after many remarkable adventures, checks, and disappointments, to get away from Dunkirk on 16th December (27th N.S.), and to reach Peterhead on the 22nd. Thence he went to Perth, where he established his Court at the ancient royal palace of Scone. He was proclaimed king and exercised regal functions; some authorities say that he was crowned.[7] But James had come too late; mutual disappointment was the result. He had been assured that the whole kingdom was on his side, but he found only dissension and discontent. His constant melancholy depressed his followers. No decisive action was taken; the project had failed even before he arrived, and Lord Mar persuaded him that he would serve the cause best by retiring and waiting for a happier occasion. James was forced to leave Scotland on 5th February 1716 (O.S.). He landed at Gravelines on 10th February (21st N.S.), went secretly to Paris, and concealed himself for a week in the Bois de Boulogne. Thence he went to Lorraine, where he was sorrowfully told by the Duke that he could no longer give him shelter. The power of Britain was great; no country that gave the exile a home could avoid a quarrel with that nation. The Pope seemed to be the only possible host, and James made his way to Avignon, then papal territory. But even Avignon was too near home for the British Government, which, through the French regent, brought pressure to bear on the Pope; the Chevalier was forced to leave Avignon in February 1717, and to cross the Alps into Italy. Here for some months he wandered without a home, but in July 1717 he settled at Urbino in the Papal States. [Sidenote: Marriage to Clementina, 1719.[8]] For a time the cares of the Jacobite Court were centred on finding a wife of royal rank for the throneless king. After various unsuccessful proposals, the Chevalier became engaged to the Princess Clementina Sobieska, whose grandfather had been the warrior King of Poland. The Sobieski home was then at Ollau in Silesia; and in October 1718 James sent Colonel Hay to fetch his bride. The British Government determined to stop the marriage if possible. Pressure was put on the Emperor, who had Clementina arrested at Innsbruck while on her journey to Italy. Here the Princess remained a prisoner until the following April. The story of her rescue by Colonel Wogan is one of the romances of history, and has recently been the theme of an historical romance.[9] Wogan brought the princess safely to Bologna, and there she was married by proxy to James on 9th May 1719. While Wogan was executing his bridal mission, the Chevalier, who had almost given up hope of the marriage, had been called away to take his part in a project which seemed to augur a chance of success.
