Meanwhile the powers at variance, though extremely irritated against each other, were all equally averse to a war that might again embroil all Europe. The king of France interposed his mediation, which was conducted by the duke de Richlieu, his ambassador at Vienna. Plans and counterplans of pacification were proposed between the two crowns and the allies. At length all parties agreed to twelve preliminary articles which were signed in May at Paris, by the ministers of the Hanoverian alliance, and afterwards at Vienna, by the Imperial and Spanish ambassadors. These imported, that hostilities should immediately cease; that the charter of the Ostend company should be suspended for seven years; and that a congress should in four months be opened at Aix-la-Chapelle, for adjusting all differences, and consolidating the peace of Europe. This congress was afterwards transferred to Soissons, for the conveniency of the French minister, whose presence was necessary at court. The siege of Gibraltar was raised, after it had lasted four months, during which the Spaniards lost a great number of men by sickness, while the garrison sustained very little damage. The court of Madrid, however, started some new difficulties, and for some time would not consent to the restitution of the South-Sea ship, which had been detained at La Vera-Cruz, in the West Indies; so that sir Charles Wager continued to cruise on the coast of Spain: but these objections were removed in the sequel.
