March, 1814, his frigate was destroyed by the British in Valparaiso harbor. He afterward commanded an expedition against pirates in the West Indian waters, and was court-martialed for com- pelling the authorities at Porto Rico to apologize for imprisoning one of his officers. Porter resigned in 1826, and be- came head of the Mexican navy. In 1829 the United States appointed him consul-general to the Barbary States, and then minister at Constantinople, where he died, March 3, 1843.

In 1845 was transferred to the National Observatory at Washington, and during the Mexican War to the naval rendez- vous at New Orleans; again to the coast survey, and from 1849 to 1853 engaged in command of the California mail steamers. At the commencement of the Civil War he was appointed commander of the steam sloop-of-war, "Powhatan"; distinguishing himself in the capture of New Orleans, and commanded the gun- boat and mortar flotilla which co-oper- ated with the squadron of Admiral Far- ragut in the first attack on Vicksburg.

H., June 13, 1822; was graduated at the United States Military Academy in 1845; served in the Mexican War, and made brevet captain and major for gallantry at Molino del Rey and Chapultepec. In 1861 was appointed colonel of the 15th U. S. Infantry, displaying great gal- lantry at Cold Harbor, Malvern Hill, Antietam, and Mechanicsville. For an alleged disobedience at the second battle of Bull Run, Aug. 29, 1862, Porter was court-martialed, and on Jan. 21, 1863, was cashiered. In 1878 a trial was granted, and the court recommended that the former sentence be reversed, and that he be restored to his former rank in the army, but no decisive action was taken. In 1882 President Arthur remitted so much of the penalty as prohibited him from holding office. New evidence came to light, General Grant affirming that Porter had been unjustly treated, and a bill was introduced in Congress provid- ing for his reinstatement.
