Description
The Trident Memorial is a monument located on Clarence Esplanade in Southsea, Portsmouth. It was created around 1860 and re-erected in 1877 by Macdonald Field and Co. The memorial features a four-sided polished pink granite obelisk that stands on a stepped base, which is set on an unpolished granite slab. The inscription commemorates "forty-four Officers and Men of H.M.S. Trident who died of yellow fever in the short space of six weeks during the unusual epidemic at Sierra Leone 1859." It also notes that it was "erected by Commander F.A. Close and the surviving Officers and Men" and "re-erected by Admiral Close, 1877."
