Scovell's parents were George Scovell of
Cirencester and the daughter of John Fielding. He was
commissioned as
cornet and
adjutant in the
4th Queen's Own Dragoons in 1798. He served as Deputy Assistant Quarter Master General at the 1809
Battle of Corunna. For his service in the Peninsular War, he received the
gold cross with one clasp and the silver war medal with eight clasps. Scovell is most remembered for the crucial role he played in breaking the codes of the French forces during that war, In the spring of 1811, the French began using a code based on a combination of 150 numbers known as the Army of Portugal Code. Scovell cracked the code within two days. At the end of 1811, a new code called the Great Paris Code was sent to all French army officers. It was based on 1400 numbers and derived from a mid-eighteenth century diplomatic code (
Grand Chiffre) which added meaningless figures to the end of letters. By December 1812, when a letter from
Joseph Bonaparte to
Napoleon was intercepted, Scovell could decipher enough of it to read Joseph's explicit account of French operations and plans. The information gained proved vital to
Wellington's victory over the French at
Vitoria on 21 June 1813. In 1813 Scovell was given the task of raising, then commanding, the
Staff Corps of Cavalry, also known as the Staff Dragoons or the Corps of Gendarmerie. This formation, of four troops equipped as light dragoons (though in red uniforms), was the first formal unit of military police in the British army. The Staff Dragoons, in addition to their policing role, undertook escort and other staff-related duties and were also employed as combat cavalry on occasion. For his service at
Waterloo, he was awarded the 4th class of the
Order of St Vladimir. Scovell was made a
Knight Commander of the Order of the Bath (KCB) on 2 January 1815 and a
Knight Grand Cross (GCB) on 18 May 1860. In later life, Scovell became Lieutenant-Governor (1829–1837) and then
Governor (1837–1856) of the
Royal Military College, Sandhurst. Scovell retired from the
British Army as a general. He died at Henley Park,
Guildford and was buried in the cemetery of the Royal Military College, Sandhurst (now the RMAS). ==Family life==
