After the retreat of the rebels from Derby back to Scotland, the regiment marched to Edinburgh, where a small army was assembled under Lieut.-General Hawley, and the rebels having besieged Stirling Castle, the troops advanced, in the middle of January, 1746, to raise the siege, and halted near _Falkirk_, where a camp was formed. The rebels advanced to meet the King's forces, and a general engagement was fought on Falkirk Moor on the 17th of January. Colonel FRANCIS LIGONIER, of the THIRTEENTH Dragoons, was taken ill of a pleurisy; he was bled and blistered on the 14th of January, but no consideration could keep him from his duty, and he quitted his bed and commanded the brigade of dragoons at the battle on the 17th of January. The action was commenced by a charge of the cavalry; Colonel Ligonier led the THIRTEENTH Dragoons forward with great spirit, broke the first line of rebels, and cut down a number of opponents, but he was unable to force the second line, and a heavy storm of wind and rain beat so violently in the soldiers' faces as to produce some confusion. Lieut.-Colonel Whitney, who had recovered from his wounds received at Preston-pans and resumed his duty, was killed fighting in the midst of a crowd of Highlanders; several other officers and a number of men were also killed and wounded. The torrent of battle flowed in favour of the rebels, and one wing of the King's army retired; a few regiments, however, maintained their ground with the most heroic bravery, and were supported by Colonel Ligonier with a party of dragoons; after dark, the King's troops being exposed to a heavy rain, retired to Linlithgow. Colonel Ligonier covered the retreat with his dragoons to Linlithgow, and being drenched with rain and benumbed with cold, he was seized with an inflammation in the throat, of which he died on the 25th of January, much regretted by the regiment. The THIRTEENTH Dragoons withdrew from Linlithgow to Edinburgh, and when the Duke of Cumberland took the command of the army and advanced against the rebels, the regiment was left at Edinburgh, and directed to patrole along the roads leading westward to prevent the insurgents receiving intelligence. On the 17th of February, 1746, the colonelcy was conferred on Philip Naizon, from the lieut.-colonelcy of the first royal dragoons. The rebellion in Scotland was suppressed by the decisive battle of Culloden, on the 16th of April, 1746. [Sidenote: 1748] [Sidenote: 1749] In 1748, a treaty of peace was concluded at Aix-la-Chapelle; the dragoon regiments on foreign service returned to England, and in the early part of 1749, the THIRTEENTH Dragoons embarked for Ireland.
