USS Horace Beals (1862) was a barkentine acquired by the Union Navy during the American Civil War. She was placed into service as a cargo ship assigned to support the fleet blockading the ports of the Confederate States of America. However, at times, Horace Beals was assigned extra tasks, such as that of a hospital ship as well as an ammunition ship.
Horace Beals was purchased in New York City 14 September 1861; and commissioned at New York Navy Yard 5 February 1862, Lt. Comdr. K. R. Breese in command.
The flotilla sailed from Key West 3 March, arrived Ship Island, Mississippi, and 5 days later crossed the bar at Pass a l'Outre. When, after almost a month of backbreaking labor, David Farragut finally succeeded in getting his heavy deep-sea ships inside the mouth of the Mississippi River on 16 April, he ordered the mortar flotilla to commence operations.
Porter's ships, camouflaged with bushes and tree branches, moved up river to pre-assigned positions below Forts Jackson and St. Philip and opened fire 18 April.
During the ensuing 6-day bombardment, Horace Beals kept the mortar schooners supplied with ammunition and provisions, took on board ordnance and other stores, and embarked and cared for sick and wounded from ships of the squadron.
The mortars opened fire on the batteries at Vicksburg 26 June and continued the attack while Farragut's ships ran by the thundering hillside cannon 28 June. They repeated the service when Farragut again ran the gauntlet on his return passage 15 July.
She was ordered back to New Orleans 22 December and arrived there 1 January 1863. She arrived below the Confederate batteries at Port Hudson 16 March two days after Farragut's heavy damage passing the enemy guns at that point.
Horace Reals continued to supply ships operating against Vicksburg and Port Hudson until those last Confederate strongholds on the Mississippi were taken and President Abraham Lincoln could boast that
During the remainder of the war this reliable supply ship operated between New York City and stations in the Gulf of Mexico bringing indispensable war material to ships of the West Gulf Blockading Squadron.
Shortly after the end of hostilities Horace Beals was sold in New York City to A. Leary 30 May 1865.
