From 1823 onward, the chief scene of Charles Jenkin's activities was in the West Indies, where he was engaged off and on till 1844, now as a subaltern, now in a vessel of his own, hunting out pirates, 'then very notorious' in the Leeward Islands, cruising after slavers, or carrying dollars and provisions for the Government. While yet a midshipman, he accompanied Mr. Cockburn to Caraccas and had a sight of Bolivar. In the brigantine GRIFFON, which he commanded in his last years in the West Indies, he carried aid to Guadeloupe after the earthquake, and twice earned the thanks of Government: once for an expedition to Nicaragua to extort, under threat of a blockade, proper apologies and a sum of money due to certain British merchants; and once during an insurrection in San Domingo, for the rescue of certain others from a perilous imprisonment and the recovery of a 'chest of money' of which they had been robbed. Once, on the other hand, he earned his share of public censure. This was in 1837, when he commanded the ROMNEY lying in the inner harbour of Havannah. The ROMNEY was in no proper sense a man-of-war; she was a slave-hulk, the bonded warehouse of the Mixed Slave Commission; where negroes, captured out of slavers under Spanish colours, were detained provisionally, till the Commission should decide upon their case and either set them free or bind them to apprenticeship. To this ship, already an eye-sore to the authorities, a Cuban slave made his escape. The position was invidious; on one side were the tradition of the British flag and the state of public sentiment at home; on the other, the certainty that if the slave were kept, the ROMNEY would be ordered at once out of the harbour, and the object of the Mixed Commission compromised. Without consultation with any other officer, Captain Jenkin (then lieutenant) returned the man to shore and took the Captain-General's receipt. Lord Palmerston approved his course; but the zealots of the anti-slave trade movement (never to be named without respect) were much dissatisfied; and thirty- nine years later, the matter was again canvassed in Parliament, and Lord Palmerston and Captain Jenkin defended by Admiral Erskine in a letter to the TIMES (March 13, 1876).
In 1845, while still lieutenant, Charles Jenkin acted as Admiral Pigot's flag captain in the Cove of Cork, where there were some thirty pennants; and about the same time, closed his career by an act of personal bravery. He had proceeded with his boats to the help of a merchant vessel, whose cargo of combustibles had taken fire and was smouldering under hatches; his sailors were in the hold, where the fumes were already heavy, and Jenkin was on deck directing operations, when he found his orders were no longer answered from below: he jumped down without hesitation and slung up several insensible men with his own hand. For this act, he received a letter from the Lords of the Admiralty expressing a sense of his gallantry; and pretty soon after was promoted Commander, superseded, and could never again obtain employment.
In 1828 or 1829, Charles Jenkin was in the same watch with another midshipman, Robert Colin Campbell Jackson, who introduced him to his family in Jamaica. The father, the Honourable Robert Jackson, Custos Rotulorum of Kingston, came of a Yorkshire family, said to be originally Scotch; and on the mother's side, counted kinship with some of the Forbeses. The mother was Susan Campbell, one of the Campbells of Auchenbreck. Her father Colin, a merchant in Greenock, is said to have been the heir to both the estate and the baronetcy; he claimed neither, which casts a doubt upon the fact, but he had pride enough himself, and taught enough pride to his family, for any station or descent in Christendom. He had four daughters. One married an Edinburgh writer, as I have it on a first account - a minister, according to another - a man at least of reasonable station, but not good enough for the Campbells of Auchenbreck; and the erring one was instantly discarded. Another married an actor of the name of Adcock, whom (as I receive the tale) she had seen acting in a barn; but the phrase should perhaps be regarded rather as a measure of the family annoyance, than a mirror of the facts. The marriage was not in itself unhappy;
Adcock was a gentleman by birth and made a good husband; the family reasonably prospered, and one of the daughters married no less a man than Clarkson Stanfield. But by the father, and the two remaining Miss Campbells, people of fierce passions and a truly Highland pride, the derogation was bitterly resented. For long the sisters lived estranged then, Mrs. Jackson and Mrs. Adcock were reconciled for a moment, only to quarrel the more fiercely; the name of Mrs. Adcock was proscribed, nor did it again pass her sister's lips, until the morning when she announced: 'Mary Adcock is dead; I saw her in her shroud last night.' Second sight was hereditary in the house; and sure enough, as I have it reported, on that very night Mrs. Adcock had passed away. Thus, of the four daughters, two had, according to the idiotic notions of their friends, disgraced themselves in marriage; the others supported the honour of the family with a better grace, and married West Indian magnates of whom, I believe, the world has never heard and would not care to hear: So strange a thing is this hereditary pride. Of Mr. Jackson, beyond the fact that he was Fleeming's grandfather, I know naught. His wife, as I have said, was a woman of fierce passions; she would tie her house slaves to the bed and lash them with her own hand; and her conduct to her wild and down-going sons, was a mixture of almost insane self-sacrifice and wholly insane violence of temper. She had three sons and one daughter. Two of the sons went utterly to ruin, and reduced their mother to poverty.
