It struck me soon after my arrival in the south that the known Unionists--I mean those who during the war had been to a certain extent identified with the national cause--were not in communion with the leading social and political circles; and the further my observations extended the clearer it became to me that their existence in the south was of a rather precarious nature. Already in Charleston my attention was called to the current talk among the people, that, when they had the control of things once more in their own hands and were no longer restrained by the presence of "Yankee" soldiers, men of Dr. Mackey's stamp would not be permitted to live there. At first I did not attach much importance to such reports; but as I proceeded through the country, I heard the same thing so frequently repeated, at so many different places, and by so many different persons, that I could no longer look upon the apprehensions expressed to me by Unionists as entirely groundless. I found the same opinion entertained by most of our military commanders. Even Governor Sharkey, in the course of a conversation I had with him in the presence of Major General Osterhaus, admitted that, if our troops were then withdrawn, the lives of northern men in Mississippi would not be safe. To show that such anticipations were not extravagant, I would refer to the letter addressed to me by General Osterhaus. (Accompanying document No. 10.) He states that he was compelled to withdraw the garrison from Attala county, Mississippi, the regiment to which that garrison belonged being mustered out, and that when the troops had been taken away, four murders occurred, two of white Union men, and two of negroes. (He informed me subsequently that the perpetrators were in custody.) He goes on to say: "There is no doubt whatever that the state of affairs would be intolerable for all Union men, all recent immigrants from the north, and all negroes, the moment the protection of the United States troops were withdrawn." General Osterhaus informed me of another murder of a Union man by a gang of lawless persons, in Jackson, about the end of June. General Slocum, in his order prohibiting the organization of the State militia in Mississippi, speaks of the "outrages committed against northern men, government couriers, and negroes." (Accompanying document No. 12.) He communicated to me an official report from Lieutenant Colonel Yorke, commanding at Port Gibson, to General Davidson, pointing in the same direction. General Canby stated to me that he was obliged to disband and prohibit certain patrol organizations in Louisiana because they indulged in the gratification of private vengeance. Lieutenant Hickney, assistant commissioner of the Freedmen's Bureau, at Shreveport, Louisiana, in a report addressed to Assistant Commissioner Conway, says: "The life of a northern man who is true to his country and the spirit and genius of its institutions, and frankly enunciates his principles, is not secure where
