While the regiment was in Flanders, Charles Edward, eldest son of the Pretender, arrived in Scotland, and being joined by a number of Highland clans, he made a desperate attempt to overturn the existing government, and establish his father's authority in the kingdom. The ROYAL NORTH BRITISH FUSILIERS were ordered to return to England; they arrived in the river Thames on the 4th of November, and after landing, marched northward: the efficiency of the regiment was increased by a body of fine recruits enlisted in Scotland. [Sidenote: 1746] The regiment arrived at Edinburgh in January, 1746, and advanced with the army commanded by the Duke of Cumberland, towards Stirling, when the young Pretender raised the siege of Stirling castle and made a precipitate retreat. The pursuit was retarded by severe weather; but the army continued its advance when the season permitted, and on the 16th of April encountered the clans on _Culloden_ moor. The regiment was in the front line on this occasion, and took part in repulsing the attacks of the Highlanders, and in driving them from the field of battle with great slaughter. This victory proved decisive, and the rebellion was suppressed. The loss of the regiment was limited to seven private soldiers killed and wounded. It was encamped a short time at Inverness, and afterwards removed to Glasgow. [Sidenote: 1747] From Scotland, the regiment was again removed to the theatre of the war in the Netherlands, where it arrived in time to take part in the operations of the campaign of 1747; and it was engaged at the battle of _Val_, on the 2nd of July. On this occasion the allied army was very inferior in numbers to the enemy, and although the gallantry of the British infantry was very conspicuous throughout the action, the Duke of Cumberland was obliged to order a retreat to Maestricht. Eight rank and file of the ROYAL NORTH BRITISH FUSILIERS were killed; one serjeant and fifteen rank and file were wounded; and five men missing. [Sidenote: 1748] The regiment was again in the field in the summer of 1748. Hostilities were this year terminated by the treaty of Aix-la-Chapelle, and during the winter the regiment returned to England.[7] [Sidenote: 1751] In the Royal Warrant, issued on the 1st of July, 1751, for ensuring uniformity in the clothing, standards, and colours of the army, the following directions are given for the TWENTY-FIRST REGIMENT, OR THE ROYAL NORTH BRITISH FUSILIERS:-- "In the centre of their colours, the THISTLE within the CIRCLE OF ST. ANDREW, and the CROWN over it; and in the three corners of the second colour, the KING'S CIPHER AND CROWN. "On the grenadier caps, the THISTLE as on the colours; the WHITE HORSE, and motto over it, _Nec aspera terrent_, on the flap. On the drums and bells of arms, the THISTLE and CROWN to be painted, as on the colours, with the rank of the regiment underneath."
