In April 1822, sailors from the British warships HMS Iphigenia and HMS Myrmidon, after a brief but fierce fight, captured two Spanish and three French slave ships off the coast of what is now Nigeria. Prize crews sailed the ships to Freetown in Sierra Leone, where the international mixed commission which was competent to hear cases regarding the slave trade decided to liberate the slaves found on the Spanish schooners, as well as those slaves found on a Portuguese ship which the British naval vessels had taken earlier.
