Editing Martin Dunbar-Nasmith (section)

==Early career==
Educated at [[Eastman's Royal Naval Academy]] in [[Winchester]] and [[HMS Prince of Wales (1860)|HMS ''Britannia'']] at [[Dartmouth, Devon|Dartmouth]], Nasmith joined the Royal Navy in 1898.<ref name=odnb>[http://www.oxforddnb.com/view/article/95215 Oxford Dictionary of National Biography]</ref>

On 8 May 1912, [[King George V]] was in [[HMY Victoria and Albert (1899)|HMY ''Victoria and Albert'']] in [[Weymouth, Dorset|Weymouth]] Bay to witness Fleet manoeuvres. Because of heavy fog, the programme was disrupted, and the King expressed the desire to dive in a submarine. He embarked on [[HMS D4|HM Submarine ''D4'']], under then [[Lieutenant (navy)|Lieutenant]] Nasmith's command, and (in the words of ''[[The Times]]'' of 10 May) "made a lengthy run in her when she was submerged." What made the occasion all the more remarkable was the presence on board of his second son, [[Prince Albert, Duke of York|Prince Albert]], who was to become [[King George VI]], of [[Winston Churchill]] ([[First Lord of the Admiralty]] and future [[Prime Minister of the United Kingdom|prime minister]]), and of then Captain [[Roger Keyes]], Inspecting Captain of Submarines, who was to become the first Director of Combined Operations (the [[Commandos]]) in the early part of the Second World War. A former prime minister, [[Arthur Balfour]], was also embarked, but the then prime minister, [[H. H. Asquith]], who had been with the King's party earlier in the day, had had to return to London on urgent business and did not dive in ''D4''. Nasmith's diary records that: "We remained under water for ten to 15 minutes, during which time he showed great interest in the proceedings, periscope in particular." A ''[[Navy News]]'' article from July 2012 by [[Commander]] William Corbett (at whose parents' wedding Nasmith had proposed the toast to the health of the bride and groom), records that Nasmith often wondered what would have happened to the course of 20th century history had he sunk that day, a not unreasonable thought, given that he had very nearly sunk in the Solent in 1905 whilst in command of [[HMS A4|HM Submarine ''A4'']].<ref name="ReferenceA">{{cite journal|journal=Navy News|title=Martin Dunbar-Nasmith|date=July 2012|pages=42}}</ref>
