Osbert Mordaunt

Mordaunt was the second son of Harry Mordaunt and Annie (his cousin, née Cautley), of Apsley Guise, Bedfordshire, and a descendant of Sir Charles Mordaunt, 6th Baronet.[2] The name "Osbert" has been used by members of the Mordaunt family since the 12th century, in honour of a direct ancestor of that name;[3] others include Canon Osbert Mordaunt, the rector of Hampton Lucy, Warwickshire and a 19th-century cricket player, also a descendant of the 6th Baronet,[4] and the soldier and poet Thomas Osbert Mordaunt, of a senior branch of the family, the Earls of Peterborough.[5] Osbert Cautley Mordaunt's ancestor, Sir L'Estrange Mordaunt, 1st Baronet, descended from William, the younger brother of John, the first Baron Mordaunt; from John, the fifth Baron (created Earl of Peterborough in 1628) descended.[6][7][8]

Mordaunt was a right-handed lower-order batsman and a right-arm slow bowler. He made his debut for Somerset in a single match in 1905 against Middlesex at Lord's.[9] He made little impression in that match or in two further games in 1906, but in the very weak Somerset side of 1907 he appeared 10 times and his slow bowling took 30 wickets.[10] His best return and the only time he took five wickets in an innings came in the game against Gloucestershire, when he took five for 68 in the first innings and four for 24 in the second, sharing the wickets in the match with Talbot Lewis (there was one run out batsman).[11] After 1907, Mordaunt played only one further match for Somerset in 1910.

In 1906 and 1908, Mordaunt appeared in non-first-class matches for the Army cricket team, and a combined Army and Navy side was one of the amateur teams he played for in a handful of first-class matches against university sides after 1910.

Mordaunt joined the Somerset Light Infantry and in 1911 was on the staff of the Royal Military College, Sandhurst.[12] In 1916, with the rank of major, he was promoted to acting lieutenant-colonel and seconded as an assistant director of signals.[13] At the end of the First World War, Mordaunt is cited in a report on the final fighting in Italy as Deputy Director of Signals and had been awarded the Distinguished Service Order.[14] In 1919 he was appointed as officer commanding the School of Signals, which predated the establishment the following year of the Royal Corps of Signals, to which he was then permanently assigned.[15] He retired from the army on half pay in 1924.[16]
