"More than twenty-five years have passed since I began to collect the materials from which this pamphlet has been evolved. As a substantial basis, to begin with, I was an eye-witness of all the fighting in the vicinity of Spring Hill, that amounted to anything, from the time Forrest attacked the 64th Ohio on the skirmish line until Cleburne's Division recoiled from the fire of the battery posted at the village. Since I began collecting I have neglected no opportunity to increase my stock of information by conversation, reading or correspondence. I have twice revisited the battlefield. I have the Government volume containing the official reports, all of which I have carefully studied. Among my correspondents, on the Union side, have been Generals Stanley, Wilson, Opdycke, Lane and Bradley, besides many others of lesser rank. I am as confident, from their letters, that my paper would have the approval of those named, who are now dead, as I am sure it has the approval of General Wilson, to whom a manuscript copy was submitted for criticism.
