CHAPTER XVI.
AT CHATTANOOGA--THE ENEMY FORTIFIES LOOKOUT MOUNTAIN AND MISSIONARY RIDGE--REORGANIZING THE ARMY--REMOVAL OF GENERAL ROSECRANS -- PUNISHMENT OF DESERTERS--GRANT AT CHATTANOOGA--THE FIGHT ON LOOKOUT MOUNTAIN--A BRAVE COLOR-BEARER--BATTLE OF MISSIONARY RIDGE.
By 9 o'clock on the morning of September 22 my command took up a position within the heavy line of intrenchments at Chattanooga, the greater part of which defenses had been thrown up since the army commenced arriving there the day before.

The enemy, having now somewhat recovered from the shock of the recent battle, followed carefully, and soon invested us close into our lines with a parallel system of rifle-pits.

He also began at once to erect permanent lines of earthworks on Missionary Ridge and to establish himself strongly on Lookout Mountain.

He then sent Wheeler's cavalry north of the Tennessee, and, aided greatly by the configuration of the ground, held us in a state of partial siege, which serious rains might convert into a complete investment.

The occupation of Lookout Mountain broke our direct communication with Bridgeport--our sub-depot--and forced us to bring supplies by way of the Sequatchie Valley and Waldron's Ridge of the Cumberland Mountains, over a road most difficult even in the summer season, but now liable to be rendered impassable by autumn rains.
