ORDERED TO OCCUPY BRIDGEPORT--A SPY--THE BATTLE OF CHICKAMAUGA--GENERAL THOMAS--TREATED TO COFFEE--RESULTS OF THE BATTLE.
The Tullahoma campaign was practically closed by the disappearance of the enemy from the country north of the Tennessee River. Middle Tennessee was once more in the possession of the National troops, and Rosecrans though strongly urged from Washington to continue on, resisted the pressure until he could repair the Nashville and Chattanooga railroad, which was of vital importance in supplying his army from its secondary base at Nashville. As he desired to hold this road to where it crossed the Tennessee, it was necessary to push a force beyond the mountains, and after a few days of rest at Cowan my division was ordered to take station at Stevenson, Alabama, the junction of the Memphis and Charleston road with the Nashville and Chattanooga, with instructions to occupy Bridgeport also.
The enemy had meanwhile concentrated most of his forces at Chattanooga for the twofold purpose of holding this gateway of the Cumberland Mountains, and to assume a defensive attitude which would enable him to take advantage of such circumstances as might arise in the development of the offensive campaign he knew we must make. The peculiar topography of the country was much to his advantage, and while we had a broad river and numerous spurs and ridges of the Cumberland Mountains to cross at a long distance from our base, he was backed up on his depots of supply, and connected by interior lines of railway with the different armies of the Confederacy, so that he could be speedily reinforced.
Bridgeport was to be ultimately a sub-depot for storing subsistence supplies, and one of the points at which our army would cross the Tennessee, so I occupied it on July 29 with two brigades, retaining one at Stevenson, however, to protect that railway junction from raids by way of Caperton's ferry. By the 29th of August a considerable quantity of supplies had been accumulated, and then began a general movement of our troops for crossing the river. As there were not with the army enough pontoons to complete the two bridges required, I was expected to build one of them of trestles; and a battalion of the First Michigan Engineers under Colonel Innis was sent me to help construct the bridge. Early on the 3ist I sent into the neighboring woods about fifteen hundred men with axes and teams, and by nightfall they had delivered on the riverbank fifteen hundred logs suitable for a trestle bridge. Flooring had been shipped to me in advance by rail, but the quantity was insufficient, and the lack had to be supplied by utilizing planking and weather-boarding taken from barns and houses in the surrounding country. The next day Innis's engineers, with the assistance of the detail that had felled the timber, cut and half-notched the logs, and put the bridge across; spanning the main channel, which was swimming deep, with four or five pontoons that had been sent me for this purpose.
On the 2d and 3d of September my division crossed on the bridge in safety, though we were delayed somewhat because of its giving way once where the pontoons joined the trestles. We were followed by a few detachments from other commands, and by nearly all the transportation of McCook's corps.
After getting to the south side of the Tennessee River I was ordered to Valley Head, where McCook's corps was to concentrate. On the 4th of September I ascended Sand Mountain, but had got only half way across the plateau, on top, when night came, the march having been a most toilsome one. The next day we descended to the base, and encamped near Trenton. On the l0th I arrived at Valley Head, and climbing Lookout Mountain, encamped on the plateau at Indian Falls.
The following day I went down into Broomtown Valley to Alpine.
The march of McCook's corps from Valley Head to Alpine was in pursuance of orders directing it to advance on Summerville, the possession of which place would further threaten the enemy's communications, it being assumed that Bragg was in full retreat south, as he had abandoned Chattanooga on the 8th. This assumption soon proved erroneous, however, and as we, while in Broomtown Valley, could not communicate directly with Thomas's corps, the scattered condition of the army began to alarm us all, and McCook abandoned the advance to Summerville, ordering back to the summit of Lookout Mountain such of the corps trains as had got down into Broomtown Valley.
