There were, however, other intruders that Cowart and Rector and Greenwood designed to remove and they wanted to remove them on the ground that they were making mischief within the tribe and interfering with its institutions, or, more specifically, with slavery. The intruders meant were principally the missionaries against whom Greenwood had even the audacity to lay the charge of inciting to murder. Newspapers of bordering slave states were full of criticism,[55] just before the war, of these same men and, notably, of the Reverend Evan[56] and John Jones, the reputed ringleaders. The official excuse for removing them is rather interesting because it is so similar to that given, some thirty years earlier, in connection with the removal from Georgia. Ulterior motives can so easily be hidden under cold official phrase. That the cause of slavery within the Cherokee country was in jeopardy in the spring and summer of 1860 can not well be denied. To the men of the time the evidence was easily obtainable. Almost as if by magic, a "search organization" started up among the full-bloods, an organization profoundly secret in its membership and in its purposes, but believed to be for no other object than the overthrow of the "peculiar institution." Its existence was promptly reported to the United States government and, as was to be expected, the missionaries were held responsible for both its inception and its continuance. It was then that Greenwood made[57] his most serious charge against these men and prepared, under color of law, to have them removed. Later, in this same year of 1860, Quantrill, the Hagerstown, Maryland man of Pennsylvania Dutch origin, who afterwards became such a notorious frontier guerrilla in the interests of the Confederate cause, leagued himself with some abolitionists for the sake of making an expedition to the Cherokee country and rescuing negroes, there held in bondage.[58] The timely distrust of Quantrill, however, caused the enterprise to be abandoned even before its preliminaries had been thoroughly well arranged; yet, had the rescue been carried to completion, it would not have been entirely without precedent[59] and its very contrivance indicated an uncertainty and a precariousness of situation south of the Kansas line.
