H.M.S. Dreadnought, a hospital ship, being towed to the breakers by tugs. Wood engraving by T. Williams, November 1872.

The hulk of the Dreadnought replaced that of the Grampus in 1831. The hospital ship was entirely separate from the Greenwich hospital, catering for sick merchant mariners of any nation, under the care of the Seamen's Hospital Society. The Dreadnought was superseded in 1870, the Society moved to the infirmary of Greenwich Hospital, and the hulk was later broken up for salvage
