Dallas (late slaver Black Nymph), 1829
Type: Tender to the Sybille : this usually means that the ship's company of the Sybille were used to man the Dallas and that claims for prize money went through through the books of the Sybille ; when it comes to the payment of prize money on rare occasions the name of the tender appears, along with the mother ship i.e. Sybille, but quite often the name of the tender is rarely mentioned and only the name of the mother ship appears in the announcement made in the London Gazette e.g. the arrest by the Dallas of the Emilia on 16 Aug 1829 appears as the arrest by the Sybille. I suspect that a part of the reason for this was that many of the tenders used on the West Coast of Africa were former slave vessels, and whilst they were ideal for the job, and a well sailed schooner might well catch most other slave vessels, many senior officers appear to have been reluctant to have used former slave vessels, and since only commissioned vessels with the appropriate permissions were allowed to detain slave ships, to mention at the Admiralty that the Dallas was being used on anti-slavery duties seemed to have the reverse effect to that that one might suppose e.g. the tender Black Joke, which had a great deal of success was condemned and burnt on the arrival of the next senior officer arriving on the station, as being too leaky and expensive to maintain, much to the chagrin of those serving on the station, and particularly those who had served on the Black Joke and enjoyed her successes. So that when these former slave vessel were burnt or broken up the navy was left with vessels, that were so slow they were no match for most slave vessels in an equal race and often had to resort to using the ship's boats, which on occasion put officers and men in the boats at a considerable disadvantage if a slave ship were to fire into the boats.
