" they had been originally wicked … They will not reflect that circumstances changed them … At home these men had no cause to show their natural savagery … They were suddenly transplanted to Africa & its miseries. They were deprived of butcher’s meat & bread & wine, books, newspapers, the society & influence of their friends. Fever seized them, wrecked minds and bodies. Good nature was banished by anxiety. Pleasantness was eliminated by toil. Cheerfulness yielded to internal anguish … until they became but shadows, morally & physically of what they had been in English society … Home people if they desire to judge fairly must think of all this.30 "
