staff and line officers, together with their record and that of every non-commissioned officer and enlisted man in the regiment, from the commencement to the close of its service, will be found in the subjoined roster. The roster has been carefully transcribed from the official records, supplemented by such other information as it was possible to obtain from reliable sources, and the compiler hopes that it will, in the main, be found correct. In the following pages, the compiler has endeavored to condense the history of the regiment into a description of the most conspicuous features of its service. With the wealth of material at his command, included in the official reports extending over the long period of its service, it would have a much less arduous task to have written an extended history than to condense it into the narrow limits rendered necessary by the magnitude of the work and the giving to each organization an approximately equal amount of space.
