Arnold, Lewis, G., 1817-1871

Lewis G. Arnold was born in Perth Amboy, New Jersey and graduated from West Point in 1837, placing tenth in his class. He fought in the Second Seminole War and the Mexican–American War, where he was severely wounded at Chuburusco. After the war, he once again commanded troops in Florida, and led a detachment against the Seminole Indians in the April 1856 Battle of Big Cypress.

At the onset of the Civil War, he was promoted to Major of the 2nd United States Artillery and was assigned to Fort Jefferson at Dry Tortugas, Florida, in January 1861, leaving his command at Fort Independence, Massachusetts. In October 1861, he helped repulse a Confederate attack on Santa Rosa Island, and defiantly refused to surrender the outpost during three different Confederate artillery bombardments. He remained there until May 1862, having rendered invaluable service in defending the fort, which remained in Union hands through the war. In January 1862, he was promoted to brigadier general, and in October 1862 was transferred to command the city of New Orleans after it fell to Union forces.
