The regiment again took the field in 1748. Preliminary articles for a treaty of peace were signed at Aix-la-Chapelle, and a suspension of hostilities took place. In this year Major-General the Honorable Charles Howard was removed to the third dragoon guards, and was succeeded in the colonelcy of the NINETEENTH regiment by Colonel Lord George Beauclerk, from the eighth marines. [Sidenote: 1749] The regiment returned to England during the winter of 1748-9, and immediately proceeded to Gibraltar, where it was stationed four years. [Sidenote: 1751] On the 1st of July, 1751, a warrant was issued by authority of King George II., for establishing uniformity in the clothing, standards, and colours of the several regiments, by which the facing of the NINETEENTH was directed to be _green_. The First, or the King's colour, was directed to be the Great Union; the Second, or Regimental colour, to be the colour of the facings of the regiment, with the Union in the upper canton; in the centre of the colour, the Rank of the regiment, in gold Roman characters, within a wreath of roses and thistles on the same stalk, surmounted by the Crown.[9] [Sidenote: 1753] [Sidenote: 1755] [Sidenote: 1756] Having been relieved from garrison duty at Gibraltar, in 1753, the regiment returned to England; in 1755 it was stationed in Scotland; in 1756 it was again stationed in England. A dispute respecting the extent of the British dominions in North America having occasioned another war with France, the regiment was augmented to _two battalions_. [Sidenote: 1758] In 1758 the Second battalion was formed into the SIXTY-SIXTH regiment, under the command of Colonel Edward Sandford. [Sidenote: 1759] [Sidenote: 1760] During the summer of 1759 the regiment was encamped at Brentwood, and in 1760 at Barham Downs. [Sidenote: 1761] In 1761 the regiment was placed under the orders of Major-General Hodgson, for the attack of one of the French islands off the coast of Brittany, called _Belle-Isle_. The expedition appeared before this place on the 7th of April; but the whole island was found like one vast fortress, the little which nature had left undone by rocks and crags having been supplied by art; and the first attempt on the 8th of April, to establish a post on the island, failed. The NINETEENTH, mustering eight hundred men, under Lieut.-Colonel Robert Douglas, evinced great gallantry on this occasion in the assault of the enemy's entrenchments on the shore; the officers and soldiers rushed to the attack with heroic bravery, but were unable to ascend the steep acclivity; they attempted to help one another up, under a heavy fire, but failed, and were ordered to re-embark.
