HMS Dauntless (1847) was a wooden-hulled steam screw frigate launched at Portsmouth in 1847. Originally intended as a paddle vessel, she was designed by John Fincham and was partially redesigned to incorporate screw propulsion. In an effort to enhance her performance, she was lengthened in 1850; however, her hull lines, optimized for paddle propulsion, proved less suited to screw propulsion, limiting her engine efficiency. Despite this, she achieved a maximum steam speed of 10.3 knots (19.1 km/h). Her armament comprised eighteen 32-pounder guns on the main deck, along with four 10-inch shell guns and two 68-pounder carronades on the upper deck. Dauntless’s initial commission took place in August 1850, where she was part of the Experimental Squadron, testing new technologies and ship designs. By the summer of 1852, she was assigned to the North America and West Indies Station. During a voyage from the Virgin Islands to Barbados in November 1852, an outbreak of yellow fever resulted in the deaths of ten crew members at sea, with an additional 73 succumbing in Barbados hospital. A monument commemorates these officers and men at St. Matthias Anglican Church in Hastings, Barbados. In 1854, with the onset of the Crimean War, Dauntless sailed with the fleet to the Baltic before transferring to the Black Sea in December, carrying artillery and stores. Her gunfire played a role in repelling a Russian attack on Eupatoria in February 1855 and participated in the bombardment of Sevastopol in April, during which a 68-pounder gun burst but caused no casualties. Throughout the campaign, she contributed officers and men to the Naval Brigade manning land batteries and later took part in the bombardment of Kinburn in October 1855. After returning to the Mediterranean Fleet, she paid off in 1857. She was recommissioned in 1859 as a Coastguard base ship at Southampton, moving to the Humber in 1864 for similar duties. From 1870, she served as a tender to the Humber Coastguard ship HMS Wyvern. She was finally laid up at Devonport in 1878 and was sold for breaking on 1 May 1885. Her service record and technological adaptations reflect her role in mid-19th-century naval operations and innovations.
