{{LCommRN}} '''John Duncan de Mussenden Leathes''', (26 January, 1896 &ndash; 26 January, 1932) served in the [[Royal Navy]].

==Life & Career==
Leathes was appointed to the {{UK-Vanguard}} from mid September 1913 to 24 January, 1916.  He was then appointed to the {{UK-Verbena|f=t}}, being promoted to {{SubRN}} on 15 September 1916 and becoming the executive officer of the small ship.

On 10 May 1917, Leathes was appointed to {{UK-Dolphin}} for a course in submarines.  He was sent to {{UK-Lucia}} in July, and on 5 September, 1917 placed in {{UK-C22}}.  He was re-appointed in the submarine as an Acting Lieutenant on 15 November, 1917.

Leathes was promoted to the rank of {{LieutRN}} on 15 March, 1918.  In mid-1918, he was noted by Captain Donaldson as being of "somewhat slovenly appearance".  He served in {{UK-E23}} from June and {{UK-E31}} from August, 1918, remaining in the second boat until 9 September, 1919.

Leathes commanded Group "F" Submarines {{UK-H21}}, {{UK-H25}} and {{UK-H26}} in Reserve at Portland from 3 February to 5 May 1922. He then commanded {{UK-H50}} for a year.

His career since February 1917 had been exclusively in submarines, and this would continue until his death except for 18 months in the {{UK-Coventry|f=t}} from August 1923 to March, 1925.

Leathes was promoted to the rank of {{LCommRN}} on 15 March, 1926.

From December 1929 until June 1931, Rear Admiral (S) [[Martin Eric Dunbar-Nasmith|Dunbar-Nasmith]] repeatedly recommended him for promotion, but before he could receive the benefit of such support, Leathes died when {{UK-M2}} foundered off [[Portland]] on 26 January, 1932.
