After Gardiner’s death the command of the Thirteenth was given to Colonel Ligonier, a brave officer who had served under Marlborough, and in the following January it took part in another battle and another defeat at Falkirk Muir. The same two Regiments of Dragoons which had been engaged at Prestonpans, and another, Cobham’s, formed at Falkirk a Brigade of Cavalry under Ligonier’s orders. This affair was not so discreditable as the former. The Cavalry, very gallantly led by Ligonier, did charge the enemy, and it is said penetrated their first line. But they failed to break the second line, and the charge ended in a confused retreat. Lieut.-Colonel Whitney, wounded at Prestonpans, was killed, and the gallant Ligonier also paid for his courage with his life. Suffering from an attack of pleurisy, he insisted on getting out of bed to command his Brigade in the battle, which was fought in a storm of wind and rain. His exertions in rallying the Dragoons and covering the retreat during the following night were too much for him, and a week later he died. The Thirteenth saw no further fighting. When the Duke of Cumberland broke the Highland clans at Culloden and put an end to the rebellion, the Regiment was not present. It had been left in Edinburgh to patrol the roads, and intercept any communications between the English and Scottish Jacobites. Its share in the campaign, therefore, had not been a very satisfactory one. Perhaps it was not to be blamed for the second defeat at Falkirk, but certainly it had not won much distinction on the battlefield. All that can be said is that no troops are likely to do well in the great ordeal of war unless their discipline and general condition have been steadily maintained in peace. History abounds in such lessons. The Regiment was to do great things later under more favourable conditions, and win a fine name for itself as a fighting corps. Its time was not yet come. In 1748 the Thirteenth was once more transferred to Ireland, and there it remained for a second score of years. A Dragoon Regiment at this time seems to have been very weak in numbers, considerably under two hundred all told, officers and men, with one hundred and fifty horses. The prohibition against Irishmen had apparently been withdrawn, and by 1767 the men were almost all Irish. But none were Roman Catholics, the enlistment of these being still absolutely forbidden. The men were fine, most of them from five foot nine to five foot eleven, and “tolerably well appointed.” The officers too were mostly Irish. The barrack accommodation was still very poor, and the Regiment was scattered in detachments as before. The arms were very bad at times.
