Great success attended the efforts made to procure men for completing the ranks of the regiment, and in three weeks after the letter of service for its formation was issued, it was embodied, armed, and clothed. It was composed to a great extent of men who had entered the army at the augmentation in 1685, and had been discharged after the suppression of the Duke of Monmouth's rebellion. The regiment was speedily reported fit for duty, and on the 23rd of October orders were received for four companies to march to Colnbrook and Longford, four to Staines and Egham, and five to Windsor, Datchet, and Slough; at the same time two companies were directed to mount guard at the Castle at Windsor: thus were the first duties of the regiment those of a guard to the Royal person. On the 29th of October the quarters were changed to Maidenhead, Datchet, and Windsor; and on the 6th of November, when the Prince of Orange had landed in Devonshire, the regiment received orders to march to Greenwich and Deptford, to be in readiness to protect the establishments in the vicinity of those places, and to aid, if required, in the preservation of the peace of the Metropolis. [Sidenote: 1689] The events which followed in rapid succession occasioned the flight of King James to France, and the services of the regiment were transferred to the Prince and Princess of Orange, who were elevated to the throne by the title of King William and Queen Mary, in February, 1689. In Ireland, the army adhered to the interest of King James; but the Protestants of Inniskilling and Londonderry embraced the principles of the Revolution, and wrote to King William for assistance to enable them to preserve those places in his interest. The ninth and SEVENTEENTH regiments were directed to proceed to Ireland, to support the people of Londonderry; and the two corps sailed from Liverpool on the 3rd of April. Contrary winds forced the transports to anchor at Highlake; but they again put to sea on the 10th of that month, and on the 15th arrived in the vicinity of Londonderry. The governor, Colonel Lundy, had resolved to surrender the place to King James, who had arrived in Ireland with a body of troops from France, and this officer called a council of war, to which he stated, that there was not provision in the town for the garrison for more than ten days, and that it would be impossible to resist the army which was advancing against it, and a resolution was passed against the two regiments landing. The two colonels had received orders to obey the governor, and they accordingly returned with their regiments to England. It afterwards appeared that the governor's statements were not true; the town was defended, and King William, considering that the two colonels (Cunningham and Richards) had not sufficiently investigated the state of the fortress, and of its stores, deprived them of their commissions.
