HMS Iron Duke (1870): HMS "Iron Duke" was the last of four "Audacious"-class central battery ironclads built for the Royal Navy in the late 1860s.  Completed in 1871, the ship was briefly assigned to the Reserve Fleet as a guardship in Ireland, before she was sent out to the China Station as its flagship.  "Iron Duke" returned four years later and resumed her duties as a guardship.  She accidentally rammed and sank her sister ship, "Vanguard" , in a heavy fog in mid-1875 and returned to the Far East in 1878.  The ship ran aground twice during this deployment and returned home in 1883.  After a lengthy refit, "Iron Duke" was assigned to the Channel Fleet in 1885 and remained there until she again became a guardship in 1890.  The ship was converted into a coal hulk a decade later and continued in that role until 1906 when she was sold for scrap and broken up.
