As soon as Mount Young was in our possession, the troops were busily employed in spreading devastation through the Carib district. In Grand Sable and other parts of the country, many houses were burned, and more than 200 pettiaugres and canoes destroyed. Several hundred slaves were also sent out, under the protection of military detachments, to dig up and destroy the provisions of the enemy. On the 4th of July, a detachment of the 46th and Malcolm's Rangers took, after a sharp action, the enemy's post at Chateaubellair, near Walliabon, with a loss of 14 killed and 39 wounded of the 46th, and 2 killed and several wounded of Malcolm's.

The evacuation of St. Lucia by Brigadier-General Stewart was, however, as far as St. Vincent was concerned, attended by fatal consequences. The proximity of the former island enabled the French unceasingly to pour in new reinforcements to their Carib allies in St. Vincent; and, towards the end of August, a small British post which had been established at Owia was surprised by a detachment from St. Lucia, and the whole of the guns and large quantities of supplies captured.

Encouraged by this success, Victor Hugues resolved to endeavour to wrest St. Vincent from the British, as he had already wrested Guadaloupe and St. Lucia; and, in the middle of September, he landed in St. Lucia with a force of some 800 men. These, embarked in four vessels, which escaped the Thorn and Experiment, the British ships of war on the station, landed at Owia Bay, St. Vincent, on the morning of the 18th of September; and the force of the enemy was now so vastly superior to that of the British, that it became impossible for the latter to retain their advanced positions.

Orders were at once sent to Lieutenant-Colonel Leighton to abandon Mount Young without delay, and retire to the vicinity of Kingston. They were carried into execution on the night of the 19th. Having destroyed their supplies and left their lights burning in their huts as usual, to deceive the enemy, the troops were silently put in motion. They reached Biabou the next evening, and, bringing in the detachment which was there quartered, reached Zion Hill on the 21st; being then distributed among the posts in the neighbourhood.

The retreating British were speedily followed by the Caribs and French, who drove off the cattle from several estates, and finally took up a position on Fairbairn's Ridge, by which the communication was cut off between Kingston and the Vigie. The detachment of the 60th at the latter post being short of supplies, Lieutenant-Colonel Ritche, of the 60th, with 200 of that corps and 150 of the St. Vincent Rangers, was detached to escort the necessary stores. His division had nearly reached its destination when it fell in with the enemy; a sharp action ensued, victory was on the eve of declaring for the British, when, struck by an unaccountable panic, they suddenly gave way and fled in all directions. The supplies fell into the hands of the enemy, and a number of the mules were killed.

The news of this terrible disaster spread dismay through Kingston, for it was thought that the enemy would at once attack all the British posts. It was resolved to at once abandon the Vigie; and to facilitate this step, Brigadier-General Myers, with the 46th and Malcolm's Rangers, marched from Dorsetshire Hill, and posted himself opposite the enemy, as if threatening an attack. This movement had the desired effect. The enemy called in all the detachments which invested the Vigie, and thus enabled the officer commanding that post to retreat at night through heavy rain to Calliaqua, and thence proceed to Kingston in boats.

While the troops were using the utmost exertion to strengthen the posts in the neighbourhood of Kingston, an unexpected reinforcement arrived from Martinique, on the 29th of September. It consisted of the 40th, 54th, 59th, and 2nd West India Regiments,[18] into which latter the St. Vincent Rangers were at once drafted. Major-General Irving also came over from Martinique to assume the command.

The first effect produced by the arrival of this succour, was the retiring of the enemy from their advanced position on Fairbairn's Ridge to the Vigie, where they now collected the whole of their strength. From this post Major-General Irving determined to dislodge them; and, on the night of the 1st of October, the troops marched for that purpose. One column, consisting of 750 men, under Lieutenant-Colonel Strutt, marched by the high road and took post upon Calder Ridge, on the east of the Vigie, about three in the morning. A second column, consisting of 900 men, under Brigadier-General Myers, crossed the Warawarrow River, and detached one party to proceed round by Calliaqua, and another to move up the valley, and climb the heights near Joseph Dubuc's. With this last force was Malcolm's Corps; and, to gain the point to which they were directed, it was necessary to cross a deep rivulet and ascend a steep hill covered with bushes and wood. In doing this it suffered a heavy loss, both of officers and men, from the enemy, who fired upon it almost in security under shelter of the bushes. The British, however, still pressed on, and at length arrived on the top of the Marriaqua or Vigie Ridge. During the ascent of the hill, Malcolm's Corps lost one man killed and two wounded.

In the meantime, the remainder of the second column were struggling in vain to reach the summit of the same ridge; at a point where the enemy had strongly occupied a thick wood, and thrown up a small work. Though the opposing forces were within fifty paces of each other, not an inch of ground was won on either side. Firing commenced at seven in the morning, and was kept up till nightfall. All this time the British were exposed to a violent tropical downpour of rain, which rendered the abrupt declivity so slippery that it was almost impossible to maintain a foothold on it; and, finding he could make no impression on the enemy, the general, about 7 p.m., gave orders for the troops to retire.

During the night, the enemy, from some unknown cause, abandoned the Vigie, and that so hastily that they left behind them, undestroyed, both guns and ammunition. They continued their retreat till they reached the windward part of the island, and the British in their turn advanced. For the remainder of the year, the troops were employed in circumscribing, within as narrow limits as possible, the French and their Carib allies; and, though great hardships were endured, no engagement worthy of note took place.
