But for the slaves not sharing in this revolt it was not so easy to "bury the whole past in oblivion." The Maroons had told some very plain truths to the white ambassadors, and had frankly advised them, if they wished for peace, to mend their own manners and treat their slaves humanely. But the planters learned nothing by experience,--and indeed, the terrible narrations of Stedman were confirmed by those of Alexander, so lately as 1831. Of course, therefore, in a colony comprising eighty thousand blacks to four thousand whites, other revolts were stimulated by the success of this one. They reached their highest point in 1772, when an insurrection on the Cottica river, led by a negro named Baron, almost gave the finishing blow to the colony; the only adequate protection being found in a body of slaves liberated expressly for that purpose,--a dangerous and humiliating precedent. "We have been obliged to set three or four hundred of our stoutest negroes free to defend us," says an honest letter from Surinam in the "Annual Register" for September 5, 1772. Fortunately for the safety of the planters, Baron presumed too much upon his numbers, and injudiciously built a camp too near the sea-coast, in a marshy fastness, from which he was finally ejected by twelve hundred Dutch troops, though the chief work was done, Stedman thinks, by the "black rangers" or liberated slaves. Checked by this defeat, he again drew back into the forests, resuming his guerrilla warfare against the plantations. Nothing could dislodge him; bloodhounds were proposed, but the moisture of the country made them useless; and thus matters stood when Stedman came sailing, amid orange-blossoms and music, up the winding Surinam.
