The regiment continued to take part in the military operations against the Spaniards. Meanwhile Scotland was violently agitated by an attempt made by King Charles I. to introduce the English Liturgy. This was followed by an unfortunate misunderstanding between the King and his Parliament in England, which produced a civil war; but, in the scenes of slaughter and devastation which followed, this regiment did not take part. It was in the service of Louis XIII. of France, who was engaged in a war with Austria and Spain; and the French King had urgent occasion for the presence of the three Scots regiments[41] with his armies. [Sidenote: 1643] While the civil war was raging in England, Louis XIII. died (14th May, 1643), and was succeeded by his son Louis XIV., who was afterwards designated _Louis le Grand_; at the time of his accession he was in his minority. Notwithstanding this event the war was prosecuted with vigour, and the court of France procured, in 1643, an additional regiment of foot from Scotland, commanded by Colonel Andrew Rutherford,[42] afterwards Earl of Teviot. This regiment was designated in France _Le Régiment des Gardes Escossois_, or the REGIMENT OF SCOTS GUARDS: but the title was only honorary, as it was never employed near the royal person. The date of its formation has not been ascertained; but, as it was afterwards incorporated into DOUGLAS' REGIMENT, now the FIRST ROYALS, this corps is its representative, and its services have a place in this Memoir. Immediately after the regiment of Scots Guards arrived in France, it was ordered to advance to the relief of _Roucroy_, a town of the Ardennes, which was besieged by the Spaniards. The troops employed in this service were commanded by Louis de Bourbon, Duc d'Enghien, who was afterwards celebrated for military achievements under the title of _Prince of Condé_, or the Great Condé. The Spaniards had a superiority of numbers: the two armies engaged near _Roucroy_, on the 19th of May, when the French gained a decisive victory, and captured the cannon, baggage, and many of the standards and colours belonging to the Spaniards. Rutherford's Scots' Regiment had the honor of taking part in this battle. It was soon afterwards employed in the siege of _Thionville_, a town situated on the river Moselle; and had one captain and four men killed, and one major and several private men wounded in the attack of the counterscarp. This siege being prosecuted with vigour, the town surrendered on the 10th of August, and the regiment appears to have marched immediately afterwards for Italy.
