From Martinique the _grenadiers_, under Prince Edward (afterwards Duke of Kent), the _light_ infantry, under Major-General Dundas, and three other regiments, embarked on the 30th of March for _St. Lucia_, where they arrived on the 1st of April, and the conquest of that island was effected in three days; His Royal Highness Prince Edward, with his brigade of grenadiers, and Major-General Dundas, with his brigade of light infantry, taking possession of St. Lucia on the 4th of April. The flank companies of the THIRTY-FIRST regiment were afterwards employed in the reduction of the island of _Guadaloupe_. A determined resistance was made by the enemy; but the island was captured by the 20th of April. France did not view with indifference the loss of these valuable possessions, and in June a French armament arrived at _Guadaloupe_ for the recovery of that island. The light company, under Brevet Lieut.-Colonel Andrew Ross, highly distinguished itself on the night of the 13th of June, in attacking the enemy near _Point-à-Petre_. General Sir Charles Grey stated in his despatch:-- “Brevet Major Ross,[22] of the THIRTY-FIRST regiment, who was with the light infantry, behaved with great gallantry and good conduct on this occasion, as he has done on every other.” The light company also participated in a night attack on Fort _Fleur d’Epée_ between the 25th and 26th of June; on the day following, Brigadier-General Symes, with the grenadiers and light infantry, attacked the enemy, who was driven to Morne Mascot, where he again made resistance, but being charged with the bayonet, he fled into Fort Fleur d’Epée. Lieut.-Colonel Ross, of the THIRTY-FIRST, commanded the second battalion of light infantry on these occasions. Lieut.-Colonel Colin Graham, of the twenty-first Royal North British Fusiliers, was appointed to the command of the troops in Basse Terre, and he defended _Berville_ camp with the utmost gallantry until the 6th of October, when he was forced to surrender,--his force having become reduced by excessive exertion, and the unhealthiness of the climate, to one hundred and twenty-five rank and file fit for duty. The troops at Guadaloupe suffered severely from the climate, and the arduous duties they had to perform, and could only muster 389 soldiers fit for duty on the 1st of September.[23]
