Opposition for their withdrawal, and proceeded at once to pass several measures which would otherwise have been sharply opposed; among others, a subsidy to Denmark for a palpably Hanoverian object--the security, namely, of the little castle of Steinhorst in Holstein. [Sidenote: Walpole declares war rather than resign.] But though he had carried his convention, and although the Opposition had withdrawn, and Cardinal Fleury had offered the mediation of France, it became obvious to Walpole that he must either declare war or resign. His love of power prevented him from taking the latter and more honourable course, and, to the loss of both power and fame, he suffered himself to be dragged against his convictions into war, which was declared on the 19th of October. The joy of England was very great, although Walpole was full of gloomy forebodings, for, as he himself said, "no man can prudently give his advice for declaring war without knowing the whole system of the affairs of Europe as they stand at present.... It is not the power of Spain and the power of this nation only that we ought in such a case to know and to compare. We ought also to know what allies our enemies may have, and what assistance we may expect from our friends." He felt certain that the area of the war would soon be extended, for, although he had successfully used his efforts to maintain friendship with France, he knew that there was an intimate connection between France and Spain which must sooner or later bring the former into the field. Moreover, his information as to the plans of the Jacobites was exceedingly accurate, and while the Opposition were constantly deriding the notion of any formidable organization of that party, he never ceased to be on his guard against it. The justice of his views was at once shown, when the declaration of war called to life the slumbering energy of the Jacobites. Intrigues were immediately set on foot; a Committee was appointed in England; overtures were addressed to Spain; and, as Fleury gradually grew colder and more estranged from England, proposals were made to him also, to which he listened, and promised that he would send a body of troops, probably the Irish Brigade, to support any attempt in favour of the Stuarts; thus would be fulfilled the condition without which the English Jacobites had always refused to rise. It was hoped that the Duke of Ormond and the Earl Marischal might make a simultaneous expedition from Spain. [Sidenote: Increased vigour of the Opposition. 1740.]
