During the summer of 1686 the ROYAL FUSILIERS were again encamped in charge of the train of artillery on Hounslow-heath. The corps assembled on the heath consisted of three troops of life guards, nine regiments of cuirassiers, three of dragoons, and thirteen battalions of foot. In a description of the camp, written at the time, and published in the Antiquarian Repertory, it is stated:--"The horse, foot, and dragoons are encamped in a straight line; the intervals between the foot is seventy paces, the intervals between each regiment of horse about fifty paces, and the interval between the horse on the left and the dragoons (because of the ground) is near half mile. The lieutenants' and ensigns' tents are in the rear of the respective companies in a direct line, seventeen paces from the soldiers' huts or tents; the captains' tents twelve paces behind the lieutenants'; the colonels' tents behind the captains', ten paces; the lieutenant-colonel on the right of the colonel, and the major on the left in a direct line. The brigadier-generals have their tents twenty paces behind the colonels'. The King's tent and chappel is in the rear of the left of the horse on the left, and the general officers' tents behind the King's. The FUSILIERS are encamped in the rear of the line, a good distance behind the interval between the Earl of Craven's regiment and the Scots guards; and in several parties about the horse carriages. The guns are planted about a hundred paces before the line, before the interval between the Scots guards and Prince George's regiment, guarded by a party of FUSILIERS; each gun having two gunners and a matrosse to attend it. The suttling booths are about two hundred paces in the rear of the line." In August the ROYAL FUSILIERS struck their tents, and, returning to the Tower with the guns, were stationed at that fortress during the remainder of the year. [Sidenote: 1687] The establishment was again augmented to thirteen companies in the spring of 1687, as appears by the following warrant:-- "JAMES R. "Whereas we have thought fit to add one company more to Our ROYAL REGIMENT OF FUSILIERS, and to apply the pay of one of the non-regimented companies mentioned in Our establishment to the entertainment of the said company of Fusiliers, with the addition of one shilling per diem to the youngest lieutenant, and one shilling and sixpence for the pay of one serjeant, and one shilling for one drummer more, Our will and pleasure is, that you include the pay of the said company, and additional allowances, within the certificates or debentures you shall from time to time make out for the pay of Our said ROYAL REGIMENT OF FUSILIERS, to commence from the 1st of January last; and for so doing this shall be your sufficient warrant. "Given at Our Court at Whitehall this 12th day of March, 1686-7, in the third year of Our reign. "By His Majesty's Command.
