Overview
Cornet was originally the lowest grade of commissioned officer in a British cavalry troop, the modern equivalent being a second lieutenant. The rank was abolished by the 1871 Cardwell Reforms, which replaced it with sub-lieutenant. Although obsolete, the term is still used as an internal title of address when referring to a second lieutenant within the British Army regiments of the Blues and Royals and Queen's Royal Hussars.
The cornet rank was also used by other nations such as the Imperial Russian Army and the Prussians.
Etymology
A cornet or "cornet of horse" was in the 17th and 18th century a term for a group of cavalry (typically 100–300 men), so-called because it was accompanied by a cornet player (a trumpet-like instrument, from Old French cornet (14c.), Latin cornū, "horn"). Later "cornet" came to refer to the fifth commissioned officer in a cavalry troop, who carried the colours; it never referred to the cornet player himself. An alternative etymology claims that the term is derived from a cornette, a woman's headdress, with a strip of lace hanging down from a headdress against the cheeks; later it referred to the pennon of a cavalry troop.
History
The rank was in use by the time of the English Civil War. Among famous cornets in that conflict were George Joyce, Robert Stetson, and Ninian Beall. It was abolished along with the purchase of commissions in the Army Reform Act of 1871, replaced by second lieutenant.
