1792
In February, 1792, the regiment proceeded from Ireland to Gibraltar.
1794
While the FORTY-SIXTH regiment was stationed at Gibraltar, the French revolutionary war commenced, and in the year 1794, the islands of Martinique, St. Lucia, and Guadaloupe were captured by the British. The French republican government fitted out an expedition for the recovery of these islands, and some success attended their efforts. This occurrence occasioned an order to be given for the FORTY-SIXTH regiment to be embarked from Gibraltar to reinforce the British troops in the West Indies. The regiment accordingly embarked in November, 1794, and arrived in the following month at the island of Martinique.
1795
The republican emissaries employed by France having organized an insurrection in the island of St. Vincent, where the native Caribs, and several of the French inhabitants were in arms against the British government, occasioned the FORTY-SIXTH regiment to be ordered to St. Vincent.
At Dorsetshire Hill, the Caribs hoisted the tri-coloured flag, and burnt every plantation in their power. The loyal inhabitants of the island assembled at Kingston, and in the fort, and every means of defence which the colony afforded, were used by Governor Seton.
It being determined to storm Dorsetshire Hill, Governor Seton selected a force for this enterprise, of which a company of the FORTY-SIXTH regiment, which had arrived from Martinique, under the command of Captain Dugald Campbell, formed part. Shortly after twelve o'clock, on the night of the 14th of March, the troops mounted the steep and rugged path in regularity and silence. They ascended within eighty yards of the main post, when they were discovered by the enemy's sentry, who challenged and fired. The Caribs, undismayed by the surprise, shouted, and opened a smart fire of musketry on the British. As soon as the troops were within twenty yards of the enemy, orders were given to fire a volley and charge, which were obeyed with the greatest alacrity. While a portion of the British force mounted the bank at one place, the detachment of the FORTY-SIXTH regiment, under Captain Campbell, ascended another part of the bank. The buildings which sheltered the enemy were stormed, but many escaped through the darkness of the night. Chatoye, the Carib king, was killed with several of his adherents, and the enemy's two pieces of cannon were captured.
Dorsetshire Hill being too extensive a position, was abandoned early on the following morning, and the British returned to Sion Hill.
The remainder of the FORTY-SIXTH regiment having arrived, enabled the governor to make a second attack upon the enemy on the 10th of April, when the Caribs were driven from their positions with considerable loss on their side, but small on the part of the British.
