English-born Thomas Armstrong (1838-1867) began his navy career in the summer of 1861. His first assignment was on the warship “Pensacola,” a screw steamer dispatched to the Gulf of Mexico to join Flag Officer David Farragut’s newly established West Gulf Blockading Squadron. On April 24, 1862, Armstrong and his crew mates steamed with the fleet past Confederate forts St. Philip and Jackson, which protected New Orleans, La. The next day, the Union vessels engaged batteries below the city, which soon surrendered. Armstrong ended the war as an acting third assistant engineer, and posed for his portrait at the New Orleans studio of Theodore Lilienthal about this time. He died of yellow fever in New Orleans in 1867. His wife, Josephine, and a daughter, Mary, survived him.
