Some trifling skirmishes, that involved nothing except a loss of men took place, instead of that active system of enterprize, which should, if possible, be ever followed in a West India warfare. The enemy gathered spirit from our inactivity, and in their turn harassed and insulted the Citadel itself, and the relief of our Guards. This error, however, afforded an opportunity of distinguishing the 61st Regiment, which was successfully employed in dislodging the enemy from the grounds they occupied. An attack being meditated against Fort Louis, upon the Grande Terre, or North East side of the Island, a Squadron was ordered, under Captain Harman, of the Berwick, with some Companies of the Highland Regiment, under Major Campbell, of the Marines; he having also a considerable detachment of his own Corps. The whole proceeded to execute this service upon the 6th of February, from which day, till the 13th, the ketches continued a brisk bombardment. The Squadron advanced to the contest early on that morning, and after five hours cannonade, silenced the Fort and its numerous dependant batteries. During this attack, the Highlanders and Marines were in the flat-bottomed boats, ready to seize upon the first favourable moment for debarkation; and on this signal being made they bravely pushed ashore, under a heavy resumed fire from every point of the enemy's defence. Major Campbell, upon this occasion, allowed them no breathing time; for finding that the ammunition was generally injured by landing at an improper place, he resolutely pushed on with fixed bayonets, and after a severe action carried the Fort, with, all the batteries. This was not accomplished without a considerable loss. An unhappy plan of procrastinated operation continued to mark our progress in the neighbourhood of Basseterre, which assumed, however, a more active form under Gen. Barrington, who succeeded to the command of the Army, after the death of General Hopson, on the 27th of February.--Resolving to change the plan of operation, he withdrew his forces from Basseterre, leaving a garrison in Fort Royal, and blowing up the other works. The whole now directed their course to Fort Louis on the 7th of March, where the transports did not arrive until the 20th, owing to the prevalence of strong lee currents. Intelligence being received of a powerful French Squadron having reached Martinique, induced the Commodore to leave the Army at this critical period to their own energies, and to proceed whither he might be enabled to counteract its future schemes. Accordingly the Marines were withdrawn from the shore, and distributed amongst their proper ships; but such was their reduced state in consequence of this service, that detachments were also necessarily solicited from the General to supply the heavy casualties which had occurred to them.
