After passing the winter in quarters at Dendermond, the regiment joined the army in May, 1711, and it took part in the movements by which the boasted impregnable French lines were passed at _Arleux_ on the 5th of August. The regiment was afterwards employed in the siege of _Bouchain_, in which service obstacles of the greatest magnitude had to be overcome, and the abilities of the commanders, with the valour of the troops, were put to a severe test. These qualities were found in the besieging army; on more than one occasion the soldiers fought up to their middle in water, and by a gallant perseverance, which reflected honor on all the corps engaged in the siege, every difficulty was overcome; and the garrison surrendered on the 13th of September. [Sidenote: 1712] The regiment joined the army commanded by the Duke of Ormond, in the campaign of 1712, and advanced to the frontiers of Picardy; but a suspension of hostilities was soon afterwards proclaimed, preparatory to a general peace, when the British army marched to Ghent, and afterwards went into quarters. [Sidenote: 1713] A treaty of peace was concluded at Utrecht, and the soldiers of the NORTH BRITISH FUSILIERS could look back with exultation at the career of victory and honor which had attended their corps during these memorable campaigns. At this period the regiment is designated by historians, and in official documents, by the title of the ROYAL NORTH BRITISH FUSILIERS; but the date when this honorary distinction of "ROYAL" was conferred upon it, has not been ascertained. [Sidenote: 1714] The ROYAL NORTH BRITISH FUSILIERS were stationed in Flanders until the decease of Queen Anne, on the 1st of August, 1714, and the accession of King George I., when they were ordered to embark for England. They landed at Gravesend on the 23rd of August, and were afterwards directed to march to Scotland. [Sidenote: 1715] In 1715 the Earl of Mar[6] erected the standard of rebellion in Scotland, and summoned the Highland clans to aid him in establishing the Pretender on the throne. The ROYAL NORTH BRITISH FUSILIERS were encamped at Stirling, under the command of the Duke of Argyle, and advanced with the Royal army to _Dumblain_, to defeat the attempts of the enemy to march southward. On the morning of the 13th of November the two armies confronted each other on _Sheriff-muir_. On the approach of the clans, it was found necessary for the Royal forces to change position, and this movement was executed at a critical time with steadiness; but several corps were suddenly attacked by the clans while in the act of forming, and suffered severely. The left wing of the rebel army was overpowered, and driven from the field with great slaughter; and the left wing of the Royal army was also forced to retire; thus each commander had one wing victorious, and one wing defeated: the rebels were prevented marching southward, and retired; and the King's troops returned to their camp at Stirling.
