The USS Varuna was a wooden-hulled screw steamer constructed in Mystic, Connecticut, by Charles Mallory & Sons. Launched in September 1861, she was originally intended for merchant service between New York City and New Orleans, with a length of approximately 218 feet and a beam of 34 feet 8 inches. Her depth of hold was 18 feet 3 inches, and her tonnage was around 1,300 tons, according to the Dictionary of American Naval Fighting Ships, though other sources cite 1,247 tons burthen. Powered by vibrating-lever engines—an innovative type designed by John Ericsson—Varuna was equipped with a single screw propeller, capable of reaching speeds of about 14 knots at a draft of 12 feet. Her armament included eight 8-inch Dahlgren guns and two 30-pound Parrott rifles, making her a formidable gunboat for her size. Crew complement numbered approximately 157 sailors. Purchased by the Union Navy on December 31, 1861, during her construction, she was commissioned in February 1862. Initially ordered to escort the ironclad USS Monitor to Hampton Roads, her orders were later changed, and she was assigned to the West Gulf Blockading Squadron under Flag Officer David Glasgow Farragut. She played a significant role in the Union's campaign to capture New Orleans, participating in the April 1862 Battle of Forts Jackson and St. Philip. During the battle on April 24, 1862, Varuna led the attack upriver against Confederate forts. She engaged Confederate gunboats, notably the Louisiana gunboat Governor Moore, with both ships exchanging fire and ramming each other at close range. Varuna was struck multiple times, and after being rammed twice by Governor Moore, she sank within 15 minutes, despite her guns still firing. Her loss was a notable event in the Union's campaign, with eight of her sailors later receiving the Medal of Honor for their valor. The sinking of Varuna marked a pivotal moment in the Union's capture of New Orleans, contributing significantly to the victory. Her wreck was visible as late as 1885, and modern expeditions have located her remains near the site of her sinking. The vessel's service underscored the importance of fast, heavily armed steamers in Civil War naval operations and her participation remains a key chapter in maritime military history.
