Whilst America hath been the land of promise to Europeans, and their descendants, it hath been the vale of death to millions of the wretched sons of Africa... Whilst we were offering up vows at the shrine of Liberty... whilst we swore irreconcilable hostility to her enemies... whilst we adjured the God of Hosts to witness our resolution to live free or die... we were imposing on our fellow men, who differ in complexion from us, a slavery, ten thousand times more cruel than the utmost extremity of those grievances and oppressions, of which we complained.
