Passing next to the dragoons, the reader will have noticed that this arm was not represented in the original Army formed by Charles the Second. Notwithstanding the high reputation which dragoons had enjoyed during the Civil War, it was not until 1672 that a regiment of them was raised, and then only to be disbanded after a brief existence of two years. The Tangier Horse, now called the First Royal Dragoons, was converted into a regiment of dragoons on its return from foreign service in 1684; and four years later there was added to the establishment a Scotch regiment which bears a famous name. It was made up in 1681 of three independent troops that had been raised three years before, and was completed by three additional troops, under the name of the Royal Regiment of Dragoons of Scotland. It now ranks as the Second regiment of the Cavalry of the Line, and is known to all the world as the Scots Greys. Dragoons still preserved their original character of mounted infantry. Twelve men of each troop besides the non-commissioned officers were armed with the halberd and a pair of pistols, while the remainder were equipped with matchlock muskets, bandoliers, and, after 1672, with bayonets. In 1687 this equipment was improved by the substitution of flintlocks for matchlocks, of cartridge boxes for bandoliers, and of buckets, in addition to the old slings, for the carriage of muskets. The tactical unit of the dragoons was still called the company, though at the close of the Civil War often denominated the troop; but the tendency of dragoons to assimilate themselves to horse is seen in the substitution of cornet for ensign as the title of the junior subaltern. This tendency was perhaps the stranger, since the companies of dragoons, eighty men strong, must have presented a favourable contrast to the weak and attenuated troops of horse. A new description of mounted soldier appeared in 1683,[216] in the shape of the Horse-grenadier. I shall have more to say presently of grenadiers, when treating of the infantry, so it is sufficient to state here that Horse-grenadiers were practically only mounted men of that particular arm, who as a rule linked their horses for action and fought on foot like the dragoons. There were in all three troops of Horse-grenadiers, which were attached to the three troops of Life Guards. Their peculiarity was that the two junior officers of each troop were both lieutenants, instead of lieutenant and cornet.
