After the arrival of the two general officers before mentioned, the army was told off into brigades as follows, viz. the 1st brigade, commanded by General Gibbs, consisted of the 4th, 21st, and 44th British, and 5th West India regiments; the 2d brigade, commanded by General Keane, consisted of the 85th, 93d, and 95th British, and 1st West India regiments, (observe, the West India regiments had by this time become exceedingly reduced in point of numbers from cold and hardship, which they seemed unable to bear, and very soon after almost ceased to be regiments, so many of them were sent away sick;) the artillery was commanded by Colonel Dickson, an excellent officer; the squadron of the 14th light dragoons not being able to get mounted, formed the guards at the hospitals, and at head-quarters, &c.

Every thing having been previously arranged on the morning of the 28th, we advanced in two columns, the right near the wood commanded by General Gibbs, and ours on the left by the great road near the river, commanded by General Keane. The enemy had all along kept possession of those farm-houses which lay at some distance in front of our picquets. They were consequently driven from these as we moved forward, which we did, I should imagine, to the distance of about three miles, their picquets retiring gradually before us. We here discovered that the enemy had thrown up a strong field-work, which extended from the river to the wood, and which consequently shut up every avenue to our farther advance, without fighting. We also found that their numbers had considerably increased, as we could perceive by the immense bodies of troops behind their works. As we pressed upon their picquets as they retired, we got a shot or two at them with our field-guns; but every thing remained quiet within their lines till we had arrived within about 400 yards of them, when they opened out on the head of our columns as destructive a fire of artillery as I ever witnessed. One shot struck in the column of the 85th, which knocked down two officers and about ten men. My battalion was leading, and being partly extended skirmishing, they did not offer so fair a mark for artillery as a solid body, and consequently escaped this.

The ship also, which was anchored a little in advance of their work, opened her broadside on the columns on the road at the same time. Our gun and howitzer, the only two pieces we had there, endeavoured to return the fire of the ship, but without doing her much injury. When the fire was found to be so galling, the troops were moved off the road into the fields on the right, and my battalion advancing about 100 paces farther, was ordered to lay down in a sort of ditch which was there, and to shelter themselves the best way they could. The 85th and 93d formed also more to the right, and secured themselves as well as the nature of the ground would admit. It was only intended as a reconnoissance, consequently the troops did not advance farther, as soon as the nature of their position was ascertained. It appeared to be a high dike of casks, formed as a breastwork, with a considerable quantity of artillery mounted on it, and with a sort of canal or wet ditch in front of it.

Of course, all this took some time to ascertain, during which they kept up an incessant cannonade, both from their works and from the ship. The latter poured in an immense quantity of large grape, which rendered the situation of those exposed to it extremely unpleasant. Our two fieldpieces were very soon silenced by the superior fire of the enemy, and in an hour after our arrival at this point, there was not a man left with them but the officer, who was quite a youth, but yet stood as steady as if he had been on a common parade, although all his men were knocked down about him. I never witnessed more devoted heroism than this fine young man displayed. One shot, nearly towards the last, struck off his sergeant's head, and sent his cap spinning over a ditch, where another officer and I had taken up our post. Some rockets were also tried from this point, both against the ship and the enemy's works, but those directed against the vessel flew quite wide of the mark, and totally failed. Some of those fired into the works, we saw pass over the heads of the men posted in them, but whether they produced any effect we could not see.

The enemy either had set fire to the houses near us before they retired from them, or they had fired heated shot with a view of producing that effect; but we had not been long here ere the whole of the houses in the neighbourhood were in one grand and terrific blaze of fire. I do not exactly know what was done on the right, for we could not see distinctly for some trees which grew in the garden of the farm in that direction, but imagine they encountered something similar to ourselves, as the play of artillery from the enemy's line in front of them was equally unceasing with that in our front. Not a man showed himself out of the enemy's works.

When every thing was ascertained that could be, the troops began gradually to draw off, but this was obliged to be conducted in a very cautious manner, or the loss from their fire would have been severe. The 93d retired first, by separate wings, afterwards the 85th, but ours did not leave their ground till after dark, when, I believe, some of the Yankees began to advance in a rather triumphant and bullying manner, but were taught to keep at a respectful distance by a few shots well laid in among them. A party of sailors had been sent forward to bring off the two fieldpieces, there being no artillerymen left to do it, and we had no horses. They undertook and accomplished this task most cheerfully and effectually, without a man hurt I believe.

The loss of my battalion on this occasion was not great. The army now took up a fresh position in which to bivouack, at about a mile and a half distance from the enemy's line, but which they could easily reach with the shot and shells of their larger pieces. The head-quarters were removed from Monsieur Villerey's house to a large farm or chateau behind our new lines, and which were formed in the following manner, viz.:—the 4th and 44th composed one line, with their right near the wood. The 21st formed on their left, but with an intervening space between them. The 85th and 93d formed one line on the left of the 21st, with an interval between their line and that regiment. This latter line was rather in an oblique direction, with its front towards a farm-house in advance and to the left, and where my battalion was ordered to take its station. This latter post was more exposed to the enemy's shot than any of the others; it being a good deal advanced, and being close to the river, the guns from the opposite shore ceased not firing on it, generally with hot shot. The men were put into a sugar house belonging to this chateau, the floor of which being sunk a little below the surface of the adjoining earth, protected them wonderfully; but on occasions they had their very cooking utensils knocked off the fire by the enemy's shot, in consequence of the exposed situation of this house. The acting quartermaster and myself being deemed civilians, and having no inclination to be deprived of our natural rest at night, as long as we could be allowed to obtain it, took up our abode in one of the outhouses at head-quarters, which we found unoccupied, and where our respective duties could be carried on with as much facility as if we were in the same house with the battalion, the distance between them being only about half a mile.

Here, also, the sick and wounded were brought, where they could enjoy more comfort than in the sugar-house, till an opportunity offered of sending them down to the shipping. To secure our front a little more, and to protect the troops against the shot from the opposite shore, a redoubt was thrown up about half a mile in front of the right, and pretty near the wood; while batteries and breastworks were constructed on the road, to fire on any vessels of the enemy which might come down the river. These latter were principally constructed of hogsheads of sugar, which were found in the sugar-houses of the different plantations in the neighbourhood. But nothing could have answered worse than they did for this purpose, the enemy's shot going quite through them, without being at all deadened almost by the resistance they offered. In front of the left also, inside the road, a breastwork was thrown up, which secured the persons of a corps of marines and sailors, who occupied that part of the line. This body was, soon after the 28th, landed from the fleet; and the latter, having brought small arms on shore with them, acted as a small battalion.

It is evident the enemy must have worked incessantly, from our first landing, to complete the work they occupied; for, from the information I before mentioned, as given me by one of the Spanish fishermen, it is clear they had only two guns, mounted on something like a battery, on the great road. But now that work extended even into the wood, a distance of at least three quarters of a mile, and at this time there could not be less than ten or twelve pieces of heavy ordnance mounted on it. We were told by the slaves who had remained in the houses, that the ditch behind which they had constructed this work was a sort of small canal, which the gentleman who owned the property used for the purpose of transporting the produce of his farm from thence into the river. From this time we could plainly perceive great numbers of men continually at work upon it, mostly blacks, of which they would, of course, have abundance; but their white people also (the army, we conclude) were constantly employed upon it. We could see distinctly that they were widening and deepening the canal in front of the work, and raising the parapet to a considerable height.

It was now determined to try what our heavy ship-artillery would do against this work. Accordingly, the greater part of the army were employed in bringing up these unwieldy machines, and to effect which required no slight power and perseverance, as we had no means of transport but the sheer strength of a number of men combined, to drag them successively through the deep soil. A sufficient number of them having been brought up by the 31st, strong working parties were employed all night in erecting two batteries, as near to the enemy's works as they could with safety venture, and getting the guns, carriages, and ammunition, &c., into them. These were formed principally of casks, &c., filled with earth; and I am not sure that some sugar hogsheads were not used on the occasion. However, at daylight on the morning of the 1st Jan. 1815, the whole of the troops were ordered under arms, and moved forward to nearly the same points they occupied on the 28th ult.
