Annals of the 57th Indiana Inf.
The 57th Indiana was assigned to duty as provost-guards in Chattanooga.
On Saturday, September 19th, the news was received that a battle was going on in front, but the rumors were so conflicting that it was a difficult matter to obtain the position of our army, or any definite information concerning the engagement. On Sunday morning quiet prevailed. Guards were mounted as usual, and marched down Main Street. Services were held at the churches; and though it was known that a battle was then going on, there was no excitement until noon. At 12 o'clock the order was received for the orderlies to send every man to the depot. Prisoners were arriving in large numbers, and required all of our available
force to guard them.
In obedience to orders received from our adjutant, I hunted up and reported every man in the company, not on the sick list, and returned to keep watch over our quarters, where I remained until near 4 o'clock in the afternoon. At that hour there was an almost constant stream of ambulances and baggage wagons coming from the front. A large brick residence on the hill, south-east of our quarters, which had been used as an officers' hospital, was now nearly filled with wounded.
On going down Main Street I found every foot of space crowded with teams, hurrying on toward the pontoon bridge. Heavy clouds of dust almost enveloped the town, and could be seen thickly rising on the road which led to the south. Teamsters were cursing and whipping. The sidewalks were filled with the wounded, stragglers and scattered musicians, carrying drums, fifes, or brass instruments. It was one constant rush toward the river, accompanied by the almost unanimous declaration that we had better be getting on the north side of the Tennessee.
Upon reaching the depot buildings I found them crowded with prisoners, and many, unable to gain admittance, remained outside. Many of the prisoners were from Longstreet's corps, late of the rebel army in Virginia. These men were better clothed than the soldiers of Bragg's army. They had always, till now, been used to victory, and were loud in their abuse of our men who had them in charge. Some of them openly declared that before the sun set on Monday, Bragg would be in Chattanooga. Many rumors had reached us to the effect that our army had been overpowered by the arrival of heavy re-enforcements from Lee's army, but until we saw them, and listened to their abusive language, all had dared to hope that the story of rebel re-enforcements would prove untrue.
