_Andrew Johnson, Military Governor of Tennessee._ By CLIFTON R. HALL, Ph.D. Princeton University Press, Princeton, 1916. Pp. 234. This book, according to the author, is an attempt to "trace the personality of Andrew Johnson through the years 1862-1865 when the burden of military government and reconstruction in Tennessee rested principally upon his shoulders." The author has intentionally neglected to give detailed treatment of the military administration in West Tennessee by the generals of the regular army and also of the Federal trade regulations in the State. No effort is here made to trace the career of Johnson after the close of his services in Tennessee. The account is largely based on the papers of Johnson found in the _Official Records of the Union and Confederate Armies_ and on the newspapers of that period, especially the _Nashville Union_. The author is conscious of his failure adequately to present the "Confederate side of many controverted points," because of "a most regrettable dearth of material for this purpose." Dr. Hall aims to answer certain charges, among which are such as the assertion that Johnson purposely delayed the work of reconstruction and that he by rather harsh treatment excluded many unquestionably loyal men from the work of reconstruction. The purpose of the work is to show how the lesson learned by Johnson in reconstructing his own State constituted a training for the higher work to which he was so suddenly and unexpectedly called. With this end in view the writer considers first secession, and then gives a sketch of Andrew Johnson leading up to his inauguration as Military Governor. Then follow such topics as the defense of Nashville, repression under Rosecrans, military and political reverses, the progress of reorganization and the presidential campaign of 1864. Throughout the treatise an effort is made to show the arduousness of the task of the Governor-of-all-work had to do and how he summoned to his aid the constructive element and reestablished order. There is given also an account not only of the opposition of those who looked upon the Governor as a traitor but of that of the militant factions that divided on the question as to how the State should be reconstructed. Lincoln's plan of reconstruction is presented as a factor which figured largely in the problems the Governor had to solve.
