Commander Henry Martin Daniel, D.S.O., Royal Navy (15 December, 1888 – ) was an officer in the Royal Navy.

Life & Career

Daniel was made a Lieutenant on 15 September, 1909.

Daniel was appointed to Valiant as gunnery officer on 21 July, 1920, and to Iron Duke and as Squadron gunnery officer on 14 August, 1925. His record was good and contained the promising marginal appraisal that he "will do well in higher ranks".[1]

Such was not to be, however. Daniel was appointed to Royal Oak on 1 December, 1927 in which his involvement in the Royal Oak Affair following events stemming from a dance on her quarter deck just over a month later would result in his conviction on four charges, all involving acts to the prejudice of good order and naval discipline, in a court-martial held on 31 March and 2nd and 3rd April, 1929. The severe reprimand proved quite ruinous to him, in contrast to his superior, Captain Kenneth Dewar, who had been court-martialed for forwarding Daniel's letters to Vice-Admiral John D. Kelly.

On 22 December, 1933, he was declined advancement to Captain on the Retired List by action of the Second Sea Lord, who cited Daniel's court-martial convictions and a decision on the same lines by his predecessor in 1928.[2]
