On the 1st of March, 1686, a second adjutant and a second surgeon's mate were added to the establishment, and the regiment was again divided into two battalions; the first battalion consisting of eleven, and the second of ten companies; and in April the second battalion embarked at Gravesend for Scotland. At the same time the whole of the first battalion was placed in garrison at Portsmouth, from whence it marched in June following to the vicinity of Hounslow, and on the 24th of that month erected its tents on the heath, where about twelve thousand men were encamped, under the orders of Lieut.-Generals the Earls of Feversham and Dumbarton, and were frequently exercised in presence of the royal family. In July, four companies marched from Hounslow Heath, and encamped near Tunbridge Wells, to attend the Princess Anne (afterwards Queen Anne) during her residence at that place; and in August the battalion struck its tents, and marched to Yarmouth and Bungay, with a detachment at Landguard-Fort, where it passed the winter. [Sidenote: 1687] From these quarters the first battalion was removed in the spring of 1637 to the vicinity of London, where it halted a few days, and afterwards proceeded to Portsmouth, and passed the summer months in that garrison. In the autumn it marched into Yorkshire; and the men were employed dining the winter in working on the fortifications at Hull. [Sidenote: 1688] In April, 1688, the first battalion was recalled from Yorkshire, and was stationed at Greenwich, Woolwich, and Deptford, until the 26th of June, when it encamped on Hounslow Heath. In the meantime the second battalion had marched from Scotland to York. In August it proceeded to Hertford and Ware; and in September to Gravesend, where the first battalion had previously arrived from Hounslow Heath; and the two battalions being again united, occupied Gravesend, Tilbury-Fort, Sheerness, and other places along the banks of the Thames and the coast of Kent. At this period the nation was violently agitated by political events. The King, being a roman catholic, and being guided by jesuitical councils, and countenanced and encouraged by a few families of the same persuasion, was attempting to effect the subversion of the established religion and laws. At the same time many noblemen and gentlemen who felt the greatest concern for the welfare of their country had invited the Prince of Orange to come to England with a Dutch army to aid them in resisting the proceedings of the court. Thus the kingdom was divided against itself, and men were looking forward, with a mixed feeling of hope, terror, and consternation, to the great convulsion which threatened the State. The King made preparations to avert the danger, and augmented his army, when the ROYAL Regiment was increased to 26 companies, and the total strength to 1858 officers and soldiers, each battalion having now a grenadier company.
