FREDERICK DE SCHOMBERG descended from an ancient and noble family of that name of the Palatinate, or Lower Rhine; and, during the struggle made by the Protestant states of Europe against the power of Austria and Spain, he served under Frederick Henry Prince of Orange, after whose death he engaged in the service of the King of France. Portugal, after having been subject to Spain many years, asserted its independence in 1640; and a sanguinary war commenced between the two kingdoms. The Spaniards had penetrated into the heart of Portugal, and were anticipating its speedy subjugation, when Louis XIV. sent General de Schomberg secretly to the aid of the house of Braganza. He was already famous for his successful defence of Bourbourg against two powerful armies, and for his conduct in the wars in Rouissillon; and, when placed at the head of the Portuguese forces, his name at once aroused the desponding adherents of the Braganza family, and inspired them with new hopes and new expectations. While his presence infused courage into the army, his discretion, for which he was always remarkable, directed its energies to advantage; towns were taken, battles were won, and finally a powerful army headed by Don John of Austria was defeated, and the Spanish monarch forced, in 1668, to acknowledge the independence of Portugal, and to conclude a peace with the house of Braganza. His success excited the surprise of Europe, and his achievements were celebrated by poets and orators in several languages.[146] After his success in Portugal he commanded a French force against the Spaniards in Catalonia; and his merits became so conspicuous, that in 1675 he was promoted by Louis XIV. to the dignity of a marshal of France. He subsequently commanded the French army in the Netherlands, and in 1676 he forced the Prince of Orange to raise the siege of Maestricht. In a few years afterwards the king of France endeavoured to suppress the Protestant religion in his kingdom, when Marshal de Schomberg, refusing to become a papist, his services appear to have been, to a certain extent, forgotten. Various means had formerly been used, and prospects of advancement to the highest honours held out, to induce him to change his religion, but in vain; and he now obtained liberty to quit France on condition of his proceeding to Portugal. Soon afterwards he obtained permission to proceed to Germany; and the emperor designed to have placed this distinguished veteran at the head of his armies, but was prevented by the influence of the Jesuits. The Elector of Brandenburg availed himself of the services of Marshal de Schomberg, and appointed him a minister of state, and Generalissimo of Prussia.
