Lewis G. Arnold was born in Perth Amboy, New Jersey and graduated from West Point in 1837, placing tenth in his class.
Graduated from the United States Military Academy, 1837.
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. After the outbreak of the Civil War, he was promoted to Major (United States) 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, Master of Arts. 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.
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.
On November 10 of that year, he was struck down by a stroke while reviewing troops, and was placed on sick leave for over a year while army officials hoped his condition would improve. When it became obvious he would be permanently disabled, he was retired from the Army in February 1864.
He remained there until May 1862, having rendered invaluable service in defending the fort, which remained in Union hands through the war.
