The sinking of HMS Peacock was a naval action fought off the mouth of the Demerara River, Guyana on 24 February 1813, between the sloop of war USS Hornet and the Cruizer-class brig sloop HMS Peacock. After an exchange of broadsides, Hornet was able to rake Peacock, forcing her to strike. Peacock was so damaged that she sank shortly after surrendering.
