HMS Surprise was a Vigilant-class gunvessel of the Royal Navy, launched in 1856 at Blackwall Yard, London, and decommissioned and broken up in 1866. Designed as a second-class despatch and gunvessel, she was intended for inshore operations, particularly during the Crimean War, and was an enlarged version of the Arrow-class gunvessel. Her construction featured a barque rig and was powered by a two-cylinder horizontal single-expansion steam engine built by Miller, Ravenhill, and Salkeld, which produced 778 indicated horsepower (580 kW), enabling a top speed of approximately 11 knots. The vessel’s armament was initially intended to include a pair of 68-pounder Lancaster muzzle-loading rifles, but she was completed with a more varied armament comprising one 7-inch (180 mm) Armstrong breech-loading gun, one 68-pound (31 kg) Lancaster muzzle-loading rifled gun, and two 20-pounder breech loaders. Her keel was laid on 30 August 1855 by Money Wigram & Son, and she was launched on 6 March 1856. She was commissioned shortly thereafter, with Commander Charles Egerton Harcourt-Vernon taking command from 18 March 1856, and later served in various theaters. Her service history included deployment in the East Indies during the Second Anglo-Chinese War under Commander Cresswell from 1857, and subsequently as part of the Mediterranean Fleet from 1861. Notably, between August 1864 and April 1866, she was commanded by George Tryon, who would later become infamous for the loss of HMS Victoria in 1893. HMS Surprise's operational lifespan was relatively brief, ending with her sale to Marshall of Plymouth and subsequent dismantling in November 1866. Her design and service reflect the transitional period of naval technology and tactics during the mid-19th century, particularly the shift toward steam-powered vessels capable of inshore operations.
