On the 8th of September batteries mounting fifty-four pieces of ordnance opened a tremendous fire upon the citadel. In less than three hours the enemy hoisted a flag of truce, and, after some discussion, surrendered. As a testimony of the royal approbation of the signal valour evinced by the ROYAL SCOTS during this siege, and of the value attached to their services, they were permitted to bear the words "ST. SEBASTIAN" on their colours. Their loss in the successful storm of the town was, Ensign Boyd, 3 serjeants, 1 drummer, and 48 rank and file, killed; Lieutenants Armstrong, Holebrooke, Macdonnell, Clark, and Suckling, 7 serjeants, and 133 rank and file, wounded. Captain James Stewart, who was performing the duty of aide-de-camp to Major-General Hay, was killed from the castle while reconnoitring the works on the 4th of September. Captain Robert Macdonald was promoted to the rank of Major in the army, for his distinguished services at the storm of St. Sebastian. After the capture of this fortress the troops advanced to the frontiers; and on the 7th of October the light company of the ROYAL SCOTS, commanded by Lieutenant J. N. Ingram, crossed the _Bidassoa_, followed by the remainder of the battalion and that portion of the army which had reduced St. Sebastian; the ROYAL SCOTS being the first British corps of the allied army which entered France. Thus, after driving the legions of Napoleon out of Portugal and Spain, the seat of war was transferred to the enemy's country; and the interior of France became the scene for the display of British prowess. After crossing the Bidassoa the troops drove the enemy to the heights of Irun, a distance of about three miles. On the 10th of November the enemy's formidable line of works on the river _Nivelle_ were attacked, and the ROYAL SCOTS, with the other regiments of the 5th division, drove the enemy from a field redoubt, and pursued them under the guns of Bayonne. The battalion lost, on this occasion, 1 rank and file, killed, and 4 serjeants and 15 rank and file wounded. Further operations were retarded by snow and rain; but in the early part of December the army passed the river _Nive_, and drove the French into their entrenched camp in front of Bayonne; from whence they issued on the three following days, and attacked the allies, but were repulsed. The ROYAL SCOTS were warmly engaged on these occasions, and their gallantry was rewarded with the royal permission to bear the word "NIVE" on their colours. Their loss was 3 rank and file killed, and 1 serjeant and 3 rank and file wounded. [Sidenote: 4th Batt.]
