The spring had not come yet, and Mons had been already invested on the 15th of March by a French army. Louis XIV. arrived there with the Dauphin on the 12th, and, despite the impetuous efforts of William to relieve the place in time, it capitulated almost in sight of the allied army. The vigilance of Marshal de Luxembourg baffled William's maneuvres throughout the campaign.
When he returned to England in October, the advantage was with France everywhere on the Continent. The Duke of Savoy had adhered to the Grand Alliance, but Nice had fallen into the power of Catinat. Opening the session of Parliament, the King spoke complacently of the successful issue of the war in Ireland; at the same time he warned the representatives of the nation that a great effort would be necessary against the King of France, and in order to support the Grand Alliance. The subsidies had been voted without opposition, and the House was engaged with the affairs of the East India Company, when a strange report was spread abroad: the Earl of Malborough, lately at the head of the English contingent to the allied army, while the king of England was absent, had been suddenly stripped of his employment and his dignities. The Princess Anne, who persisted in keeping her favorite with her, had to retire with her to the country. The causes of Malborough's disgrace remained a mystery, which occasioned the most diverse conjectures, and allowed the enemies of William and Mary to attribute unworthy or frivolous motives to them. The cause was grave, and the necessity absolute: the Earl of Marlborough was hatching a new treason. In the Parliament and the army all was ready to attempt a Jacobite restoration.
James II. himself wrote in November, 1692: "Last year my friends formed the design of recalling me by act of Parliament. The method was arranged, and Lord Churchill was to propose in Parliament to expel all foreigners, as well from the army and the council as from the kingdom. If the Prince of Orange had agreed to this measure, they would have had him in their hands; if he had resisted it, they would have made Parliament declare against him, and at the same time Lord Churchill with the army was to declare himself for the Parliament; the fleet was to do the same, and they were to recall me. They had commenced to move in the matter and had gained a large party, when some indiscreet subjects, thinking they were serving me, and that what Lord Churchill was doing was not for me, but for the Princess of Denmark, had the imprudence to discover the whole thing to Bentinck, and thus averted the blow."
