A view of the headstone for Neils Christian Petersen, Danish Interpreter of HMS 'Alert'. Petersen died on 14 May 1876 from the after-effects of severe frost-bite, which he sustained during the first attempt to communicate with 'Discovery' after the winter. The party consisted of Sub-Lieutenant Egerton and Lieutenant Rawson, with Petersen acting as dog driver for the dog sledge. The team left 'Alert' (1856) on 12 March 1876, but on the second day Peterson complained of cramp in the stomach, and subsequently was unable to keep warm and suffering from frost-bite. As a result the two officers transported Petersen on the dog sledge back to the ship. Peterson later had both feet amputated, and had lost portions of his nose and ears, as a consequence of the frost-bite. The stone also records the death of George Porter, Gunner Royal Marine Artillary, on 8 June 1876 from the effects of scurvy. Porter had shown signs of scurvy on 17 April 1876 with swollen and puffy knee joints. Subsequently, he had to be dragged on the sledges as he was unable to walk. Porter died on the return journey of the Northern Party's expedition to the North Pole near Cape Joseph Henry, 30 miles from 'Alert', and was buried in the ice.
