Great Natural Obstacles

The Campaign For Chattanooga (The Middle Tennessee Campaign):

"...General Rosecrans at once began the most vigorous preparations for another campaign for the occupation of Chattanooga.

"...those who were on the ground know well the unceasing activity and energy with which the work of accumulating sufficient supplies of food, material, and ammunition progressed, preparing the means for crossing the Tennessee, and obtaining the necessary knowledge of the mountain passes, roads, and trails by which the army must move."

"A glance at the atlas of the Park Commission will disclose the great natural obstacles which lay between General Rosecrans and Chattanooga."
