Thoughts upon the African Slave Trade

The nature and effects of that unhappy and disgraceful branch of commerce, which has long been maintained on the Coast of Africa, with the sole, and professed design of purchasing our fellow-creatures, in order to supply our West-India islands and the American colonies, when they were ours, with Slaves; is now generally understood. So much light has been thrown upon the subject, by many able pens; and so many respectable persons have already engaged to use their utmost influence, for the suppression of a traffic, which contradicts the feelings of humanity; that it is hoped, this stain of our National character will soon be wiped out.
If I attempt, after what has been done, to throw my mite into the public stock of information, it is less from an apprehension that my interference is necessary, than from a conviction that silence, at such a time, and on such an occasion, would, in me, be criminal. If my testimony should not be necessary, or serviceable, yet, perhaps, I am bound, in conscience, to take shame to myself by a public confession, which, however sincere, comes too late to prevent, or repair, the misery and mischief to which I have, formerly, been accessary.
I hope it will always be a subject of humiliating reflection to me, that I was, once, an active instrument, in a business at which my heart now shudders. My headstrong passions and follies plunged me, in early life, into a succession of difficulties and hardships, which, at length, reduced me to seek a refuge among the Natives of Africa. There, for about the space of eighteen months, I was in effect, though without the name, a Captive and a Slave myself; and was depressed to the lowest degree of human wretchedness. Possibly, I should not have been so completely miserable, had I lived among the Natives only, but it was my lot to reside with white men; for at that time, several persons of my own colour and language were settled upon that part of the Windward coast, which lies between Sierra-Leon and Cape Mount; for the purpose of purchasing and collecting Slaves, to sell to the vessels that arrived from Europe.
