William D. Porter

William David Porter (10 March 1808 – 1 May 1864) was a flag officer of the United States Navy. He was the son of Commodore David Porter (1780–1843) and brother of Admiral David Dixon Porter (1813–1891) as well as foster brother of Admiral David Farragut (1801–1870).

Early career
Porter was born on 10 March 1808 in New Orleans, Louisiana. He spent much of his childhood in Chester, Pennsylvania. After an early and unsuccessful attempt to stow away on his uncle John Porter's, ship-of-the-line USS Franklin (1815), he signed on Franklin at the age of 12. Porter was appointed a midshipman on 1 January 1823, and 11 years later was commissioned a lieutenant. From 1838 to 1840, he served as lighthouse inspector for the portion of the east coast between Norfolk, Virginia, and New York. That duty was followed in 1840 with an assignment at the Washington Navy Yard as ordnance officer. During this assignment, he became interested in the development of an explosive shell suitable for naval use. After leaving Washington, Porter spent the next decade superintending the outfitting of new steam ships for the Navy, commanding supply vessels, and delivering mail and supplies to Navy units abroad.

Following retirement between 1855 and 1859, he returned to active duty and took command of the sloop-of-war USS St. Mary's (1844). He patrolled the Pacific coasts of Mexico and Central America for two years protecting American interests in that area.

Civil War
The secession of Southern states in 1860 and 1861 caused St. Mary's to be recalled to her base at Mare Island, California. In the summer of 1861, Porter was relieved of command of the ship and ordered to Washington, D.C. In the autumn, he was assigned to special duty in St. Louis, Missouri, to assist in establishing the Western Flotilla to seize and control the Mississippi and its tributaries for the Union. On 3 October, he was given the command of a ferryboat-turned-gunboat New Era. Serving under Flag Officer Andrew Foote, he patrolled the Cumberland River, keeping a wary eye upon the growing Confederate defenses along the river. In November, he took his ship to St. Louis for repairs; and, upon his return to the flotilla at Cairo, Illinois, New Era sported a new name, USS Essex (1856), in honor of the frigate USS Essex (1799), which Porter's father had commanded during the War of 1812.

Between January and August 1862, Porter served gallantly up and down the Mississippi River. On 10 January, Essex and USS St. Louis (1861) engaged three Confederate gunboats and forced them to retreat to the protection of Southern shore batteries. The two Union gunboats repeated the feat three days later and succeeded in damaging their opponents. Only Confederate shore batteries prevented the capture of the three steamers.

On 6 February, Essex joined the rest of Foote's gunboat squadron in the attack on Fort Henry. Porter's ship, second in line, sustained heavy fire from shore batteries and received at least 15 direct hits. About half an hour into the fray, Essex took a 32-pound shot through her bow shield. It pierced her boilers, releasing steam which severely scalded 28 men. Commander Porter—himself blinded and scalded—continued to conn his ship until she was clear of the action.

Though still severely hampered by his injuries, Porter directed the extensive repair and renovation of Essex from his sick bed. At the same time, he also superintended the construction of two other warships, the ironclads USS Lafayette (1848) and USS Choctaw (1856).

Porter completed the renovation of Essex at St. Louis in July and rejoined the Western Flotilla at Vicksburg, Mississippi, later that month. At dawn on the 22nd, Porter took Essex out to confront the Confederate ironclad ram CSS Arkansas which had recently left her refuge in the Yazoo River to seek greater safety under the cover of Vicksburg's shore batteries. In company with the smaller converted riverboat USS Queen of the West (1854), Essex moved in toward the Southern warship. During the approach of the two Union ships, Confederate shore batteries subjected them to a withering fire. Finally, Essex struck Arkansas a jarring blow but at an oblique angle. As a result, she glanced off the Southern ram and ran aground parallel to her adversary. Porter worked furiously to free his ship and, after much difficulty, managed to retire, with Queen of the West close behind.

Thereafter, since Essex had sustained only minor damage, Porter kept her on station patrolling the lower Mississippi River between Vicksburg and Baton Rouge. On 5 August, his ship and USS Sumter (1862) assisted Union Army troops in repelling a Confederate land attack on Baton Rouge. The following morning, he headed north to Vicksburg to confront Arkansas once more. He found his quarry on a bend in the river, close to the shore. In the ensuing bombardment, Porter used an incendiary shell which he himself had invented. After about 20 minutes of shelling, Arkansas erupted into flames and soon blew up. Evidence suggests that the Confederate crew had set their own ship afire to prevent her capture. Be that as it may, Porter's bold action played no small part in the ram's destruction. Moreover, Congress recognized the role played by Porter and his ship in June 1864 when they belatedly awarded the Essex crew $25,000 in prize money.

Porter's last real action in the war occurred in September 1862 when Essex conducted a bombardment of Natchez, Mississippi, and duelled the shore batteries at Port Hudson, Louisiana. Later that month, he returned to New Orleans where new orders awaited him. Promoted to the rank of commodore, Porter was assigned to duty at New York. There, he served in various capacities until hospitalized in April 1864. On 1 May 1864, Commodore Porter died of heart disease at St. Luke's Hospital in New York City, New York. Although he was buried initially at Greenwood Cemetery in New York, he was moved to The Woodlands, Philadelphia, Pennsylvania, in June and laid to rest beside his famous father, Commodore David Porter.

Namesake
In 1942, the destroyer USS William D. Porter (DD-579) was named in his honor.
