On 25th March 1807 the Royal assent was given to a Bill for the total abolition of the British slave trade on and after 1st January 1808. At first only a penalty of money was exacted from those who were convicted of slave-dealing. This, of course, was soon found to be without much effect, and in consequence, in 1811, slave-dealing was made punishable by transportation for fourteen years. Even this was found to be very inadequate. The slave-dealer knew that the risks of his being caught at his illicit trade were very small, and as the profits were very great he was quite willing to run that risk. Slave-dealing still continued with renewed zeal, and, if possible, greater cruelty than before. In 1824, therefore, the offence was declared to be piracy, and punishable with death. In 1837, however, the punishment inflicted on British subjects for trading in slaves was changed to transportation for life. A squadron of small vessels supposed to be suited for the purpose was forthwith equipped and sent to the African coast, to capture slavers wherever they could be found north of the equator, either embarking their cargoes or prepared to receive them, or with full ships, and whether up rivers, on the coast, or out at sea. These expeditions were full of excitement for the bluejackets, and countless were the chases after slavers by the ships of the squadrons. The danger was great in many cases. The slave-dealers were of the lowest grade of humanity, and cruel to the last degree. The barbarity with which they tore away the poor blacks from their native country, and the cruelty with which they treated them on board, is indescribable. The slaves were treated worse than animals, and many died during the voyage, but that mattered little to the slave-dealer, who had paid nothing for them, and who could find plenty more where they came from. Often the slave-dealers had on board, or rather in the hold of the ship, something like 900 slaves. When the decks were battened down during storms the tortures they endured were frightful. Often when the hatches were opened after a hurricane more than one-third of the slaves were found to be dead from suffocation or want of food, and often, sooner than have the trouble of hauling up the dead bodies, the hatches were battened down again and the poor slaves left in their misery till the end of the voyage, when perhaps another third were found to have died. It was to prevent atrocities such as these that our sailors were called upon to perform such gallant deeds on the African Coast, and their gallantry and powers of endurance were never displayed to better purpose than during the chases and captures of slavers. Accounts of some of them are given, to show the sort of work our officers and men are called upon to perform to keep down this horrible evil.
