Bastia was afterwards besieged by sea and land, and surrendered on the 22nd of May. An assembly of the Deputies afterwards agreed to unite the island to Great Britain, which was performed with the solemnities customary on such occasions. But _Calvi_, a fortified town thirty-three miles from the capital, and situated on a tongue of land which forms one of the most beautiful harbours in the island, still held out; and the ROYALS formed part of the land force commanded by Lieut.-General Stuart selected for the siege of this place. The battalion accordingly embarked from Bastia, and, having landed near Calvi on the 19th of June, took post on a ridge of mountains three miles from the town. Owing to the numerous rocky heights and steep mountains before the town, the soldiers and seamen had to make roads along difficult precipices, to drag the guns up the mountains, and to carry up materials for erecting the batteries, which they performed with cheerful alacrity. The fire of the heavy artillery having made a practicable breach on the west side of the Mozello, on the 18th of July the light infantry and ROYALS, commanded by Lieut.-Colonel Moore, "proceeded with a cool, steady confidence, and unloaded arms, towards the enemy, forced their way through a smart fire of musketry, and, regardless of live shells flung into the breach, or the additional defence of pikes, stormed the Mozello; while Lieut.-Colonel Wemyss, with the Royal Irish Regiment, and two pieces of cannon, under the direction of Lieutenant Lemoine, equally regardless of opposition, carried the enemy's battery on the left, and forced the trenches without firing a shot."[104] The capture of these posts proved of great importance, and, the siege being continued with vigour, the garrison surrendered on the 10th of August. The loss sustained by the 2nd battalion of the ROYAL Regiment was very trifling, viz., about four men killed and Captain Colin M'Donald and seven men wounded. The battalion was afterwards stationed in garrison at Calvi, where it remained nearly two years. [Sidenote: 1st Batt.] The republican principles which produced the revolution in France soon extended to the French West India settlements; and the inhabitants of colour in the island of _St. Domingo_ (now the black empire of Hayti), having imbibed the doctrine of equality, rose in arms against the whites, and carried fire and bloodshed through the settlement. Many of the planters having, from the distracted state of France, no hope of relief from that country, were desirous of placing themselves under the protection of Great Britain: a body of troops was accordingly sent to their aid, under the command of Lieut.-Colonel Whitelocke; and while the 2nd battalion of the ROYAL Regiment was engaged in the defence of Toulon and the capture of Corsica, the 1st battalion embarked from Jamaica and sailed to St. Domingo.
