Concha. I. Jose De La, marquis of Havana, a Spanish soldier and statesman, born in Cordova de Tucuman, Buenos Ayres, in 1800. He took part in the war against the patriots in South America and against Don Carlos in Spain, became lieutenant general in 1839, and was captain general of the Basque provinces from 1843 to 1846. About this time he was placed at the head of the Spanish cavalry, and in 1849 was appointed captain general of Cuba, where he distinguished himself by his energy and the reforms he effected. He was removed shortly after the insurrectionary attempt of Gen. Lopez in 1851, and on his return to Spain published a valuable statistical work on Cuba. He joined his brother in opposing the government, and was banished from Spain in January, 1854. Subsequent to the July revolution of the same year he was reappointed captain general of Cuba, but was recalled on the return of Narvaez to power in 1856. He was subsequently senator, ambassador in Paris, and member of the Miraflores cabinet. On the outbreak of the revolution of September, 1868, he was appointed by Queen Isabella prime minister, and exercised the office until she crossed the frontier into France, when he followed her into exile.

II. Mannel de la, marquis of Douro, brother of the preceding, born in Madrid in 1794. He fought in early life against Napoleon and the revolted Spanish colonies in South America, and afterward against Don Carlos. As representative of the city of Cadiz in the cortes, he gave his support to Maria Christina and Isabella, and successively to the administrations of Espartero and Narvaez. In 1843 he was commandant in Valencia and Murcia, and in 1844 captain general of Catalonia. In 1847, during the complications with Portugal, he was put in command of 6,000 men, and took possession of Oporto, by which victory he earned his title. In the same year he escorted Maria Christina to Paris, and on his return to Madrid resumed his seat in the cortes, where he was a conspicuous member of the ultra conservative party. Subsequently he was reappointed captain general of Catalonia. Having issued at the end of 1853, in concert with O'Donnell and Bravo Murillo, the famous protest against the policy pursued by the government, he was banished from Spain in January, 1854, and repaired to Paris;- but he was soon recalled to Madrid by the revolution of July of that year.

Gen. Concha was now made inspector general of cavalry and marshal; but on Oct. 12 following, when Narvaez came again into power, he was compelled to relinquish his positions. He is the author of a work on infantry and cavalry tactics, which is the accepted text book in all military schools and colleges in Spain.
