The forts and castles of the harbour of Carthagena having been demolished, the fleet sailed to Jamaica; and subsequently to the south-east part of the island of Cuba, where the soldiers landed, and a camp was formed twenty miles up one of the large rivers of this island. At this camp the SIXTH were stationed some time, and it was in contemplation to form a British settlement on this part of Cuba; the country was reconnoitred, detachments were sent out, and the Spanish villages were found deserted. For a short time a plentiful supply of fresh provisions was procured; but the men were afterwards rationed with salt and damaged meat and biscuit, and their numbers were so reduced by sickness, that in November they were put on board again, and re-conveyed to Jamaica. [Sidenote: 1742] [Sidenote: 1745] The SIXTH, having suffered severely from the effects of climate, returned to England in December, 1742, and commenced recruiting their numbers. They subsequently proceeded to Scotland, where they were stationed in the summer of 1745, when Charles-Edward, eldest son of the Pretender, raised his standard in the Highlands, and asserted his father's pretensions to the throne. The head-quarters of the SIXTH were at Aberdeen; two companies were at Inverness, which has been termed the capital of the Highlands, being the only town of importance north of Aberdeen; three companies were at Fort Augustus, situated on a plain at the head of Loch Ness, between the rivers Tarff and Oich, and built at the spot where they discharge themselves into the lake; a strong party, commanded by Captain Millar, occupied Fort William, which was built in the reign of King William III., in a plain on a navigable arm of the sea, called Loch Eil, near the influx of the Lochy and Nevis, in the county of Inverness; a serjeant's party occupied a redoubt at Ruthven; and a working party was employed on the newly-constructed roads in the Highlands. While in these quarters information was received of the arrival of the Pretender's eldest son with a few Scottish and Irish adventurers on the coast of Lochabar, and of their being joined by a number of Highlanders, under their respective chiefs. The news of this bold and hazardous undertaking was at first disbelieved, but Captain SWEETMAN of the regiment, walking out from Fort Augustus to gain information, entered an inn in the Highlands, where he was surrounded by eight rebels and conveyed a prisoner to the young Pretender's camp. There he was civilly treated, and suffered to go away on his parole; one of the Pretender's manifestos was given him, with a passport directed to all sheriffs, sheriff-deputies, and constables in Scotland, and signed _Charles Pr. Custos Reg._ After his release Captain Sweetman proceeded by post to London, where he was examined by the Privy Council, and the tidings of the rebellion were no longer doubted. The working parties of the SIXTH and other corps were then ordered to rejoin their regiments.
