The Commander in Chief feels with great concern the necessity of again assembling part of the troops to dislodge an enemy who have stolen into Pointe a Pitre, and the posts in its neighbourhood, at the moment when the gallant General Dundas was expiring. He had hoped that the troops, whose meritorious services had acquired so much glory during a most successful campaign, would have found rest and comfort during the remainder of this year at least. Relying however on the cheerful and utmost exertions of the gallant troops he has the happiness to command, he cannot entertain a doubt of finishing the service speedily and gloriously, to enable the troops to return very soon to the quarters from whence they are now called forth to service. The Commander in Chief assures the troops that their situation on this extra service shall be made as comfortable and agreeable to them as it is in his power to render it; and that no time shall be lost in advancing against the enemy, consistent with the attention he always pays to the preservation of his soldiers, not wantonly or prematurely exposing them to danger. The same conduct, good behaviour, and cool bravery, which gained such rapid and complete success hitherto, will insure it on the present occasion, against about five hundred regular troops, joined by a despicable and motley crew of mulattoes and negroes, with some seamen, the whole a forlorn hope, who put in here for the want of provisions, and at a time the forty-third regiment was weakened by sickness. The troops to be ready to get into the flat boats to-morrow morning at three o'clock. The boats, when the men are embarked, are to assemble astern of the Assurance forty-four gun ship, there waiting for orders to proceed on shore. The troops to carry on shore with them three days provisions dressed, one day's grog, and rum in kegs for another day: also to land with their tent blankets, camp kettles, water kegs, canteens, and hand hatchets; the sailors to land with ditto and tomahawks. The light infantry to be first to land with two amuzettes, supported by the battalion of grenadiers with two three-pounders. The sixty-fifth regiment then to land with two six-pounders; Captain de Rivignes commanding the artillery. After the troops are landed, and have got the heights opposite, the spare artillery, howitzers, stores, &c. are to be landed at Grozier. The commanding engineer will land at the same time all the artificers, and every thing belonging to his department, that no time whatsoever may be lost in forwarding the enterprise. The first troops that land will immediately take advantage of the strongest ground, houses, &c. there posting themselves; not advancing until the whole are landed. Brigadier General Symes will direct the landing, and is to command the troops on shore. The Commander in Chief has been pleased to appoint Captain John Cunnyngham, of the forty-third regiment, to be deputy adjutant general, vice Lyon, deceased.
