Kingsmill was a French vessel launched in 1793 under a different name, captured in 1798, and sold to British owners who renamed her.

She then became a slave ship, making three voyages from Africa to the West Indies in the triangular trade in enslaved people.

In 1807, after the end of British participation in the trans-Atlantic slave trade, Kingsmill became a West Indiaman.

[c] Mullion sailed Kingsmill to the Bight of Biafra and Gulf of Guinea islands.

[1] In 1799 he made a second slaving voyage to the Bight of Biafra and Gulf of Guinea islands and then Martinique.

He too sailed to the Bight of Biafra and Gulf of Guinea islands, but took his captives to the Bahamas.

[13] She was one of only four vessels to bring enslaved people from the Bight of Biafra to the Bahamas, and all four came from Bonny and arrived in 1802–1803.

Lloyd's List (LL) reported on 26 June 1804 that the French privateer Buonaparte captured Kingsmill as she was sailing from Liverpool to Barbados and took her into Guadeloupe.

[19][e] She sailed after George Canning wrote on 16 May 1814 to Secretary of the Admiralty John Wilson Croker requesting an exemption for her from the requirement that vessels travel in convoy.

Croker further argued that Kingsmill was well-armed and so would not be vulnerable to attacks from most privateers.

[21][f] Kingsmill, A. Cassels, master, sailed on 22 May and returned 15 months later with a profitable cargo.

Lloyd's List reported on 9 February 1821 that Kingsmill, Purnell, master, ran aground on the North Bank while sailing from Liverpool to Valparaiso.

At one point she had four feet of water in her hold, but it was believed that the dry goods were not injured.
