THREE:It was resolved to make the first attack only on the trade in slaves, not on the whole gigantic subject, with all its widely-ramified interests. Nay, it was deemed prudent by the committees, seeing well that the abolition of the monstrous practice of slave-holding must be a work of many years, in the first place to limit their exertions to the ameliorating of the sufferings of the negroes, in their passage from Africa to the scenes of their servitude. Numerous petitions had now reached the Houses of Parliament on the subject of the trade in and the sufferings of slaves, and a Committee of the Privy Council was procured to hear evidence on the subject. This commenced its sittings on the 11th of February, 1788. Before this committee were first heard the statements of the slave merchants of Liverpool. According to these gentlemen, all the horrors attributed to the slave trade were so many fables; so far from instigating African sovereigns to make war upon their neighbours and sell them for slaves, the oppressions of these despots were so horrible that it was a real blessing to bring away their unfortunate victims. But very different facts were advanced on the other side. On the part of the Liverpool merchants was the most palpable self-interest to colour their statements; on the other, was disinterested humanity. Amongst the gentlemen brought forward to unfold the real nature of the African traffic was Dr. Andrew Sparrman, Professor of Natural Philosophy at Stockholm, who had, with Mr. Wadstr?m, been engaged in botanical researches in Africa. This information put to flight the pleasant myths of the Liverpool traders, and produced a profound impression.No sooner was this treaty signed than Junot was ordered to cross the Bidassoa with thirty thousand men, and march through Spain for the Portuguese frontier. Two additional armies, partly of French and partly of Spaniards, supported him, and another army of forty thousand was stationed at Bayonne, intended, it was said, to act as an army of reserve, in case the British should land and attempt to defend Portugal, but in reality it was intended for the subjugation of Spain itself. Junot, who had formerly been Buonaparte's ambassador at the Court of Lisbon, made rapid marches through Spain. The Prince Regent of Portugal, knowing that resistance was in vain, sent the Marquis of Marialva to state to the Courts of France and Spain that he had complied with the whole of their demands, as regarded the admission of British goods, and demanded the arrest of the march of the invading army. But no notice was taken of this, and Junot pushed on with such speed as to exhaust his troops with fatigue. He was anxious to seize the persons of the royal family, and therefore this haste, accompanied by the most solemn professions of his coming as the friend and ally of Portugalas the protector of the people from the yoke of the British, the maritime tyrants of Europe.
