DRAGOON, originally a mounted soldier trained to fight on foot only. (See CAVALRY and MOUNTED INFANTRY.) This mounted infantryman of the late i 6th and early centuries, like his comrades of the infantry who were styled "pike" and "shot," took his name from his weapon, a species of carbine or short musket called the "dragon." Dragoons were organized not in squadrons but in companies, like the foot, and their officers and non-commissioned officers bore infantry titles. The invariable tendency of the old-fashioned dragoon, who was always at a dis advantage when engaged against true cavalry, was to improve his horsemanship and armament to the cavalry standard. Thus "dragoon" came to mean medium cavalry, and this significance the word has normally retained since the early wars of Frederick the Great. The light cavalry of the British army in the i 8th and early 19th centuries was for the most part called light dragoons. The phrases "to dragoon" and "dragonnade" bear witness to the mounted infantry period, this arm being the most efficient and economical form of cavalry for police work and guerrilla war fare. The "Dragonnades," properly so called, were the operations of the troops (chiefly mounted) engaged in enforcing Louis XIV.'s decrees against Protestants after the revocation of the edict of Nantes.
