Dana Quote:
"My report to-day is of deplorable importance," began Dana's, missive. "Chickamauga is as fatal a name in our history as Bull Run, "Dana then went on for several hundred more words, painting a picture of unmitigated disaster. In describing the Rebel breakthrough, Dana wrote that the Confederates "came through with resistless impulse. . . Before them, our troop turned and fled. It was wholesale panic. Vain were all attempts to rally them. . .the road is full of a disordered throng of fugitives. Davis and Sheridan, "Dana continued, "are said to be of at the head of a couple of regiments in order. Wilder's brigade marches out unbroken. Thomas, too is coming down the Rossville road with an organized command, but all the rest is in confusion." Dana estimated Union losses at "20,000. and may be much more," with 6,000 wounded abandoned to the Rebels. "Enemy not yet arrived before Chattanooga," he concluded. "Preparations making to resist his entrance for a time." pp705 The Chickamauga Campaign by Powell
Think the Bull Run analogy, did the most damage! This was the first impression of the Battle to be reported to Washington. First Impressions are hard to overcome. Dana was a tool of Stanton. He just gave Stanton the ammo he needed to Cashier Rosy. Something he had been trying to do.
So, 1/3 of the Federals Army is Routed. Flee in Panic. Rosecrans, McCook, Crittenden and Negley, Cashiered. They lose all of their Hospitals. 2.5K wounded with 52 surgeons captured. Lose 20 artillery pieces. Should of been much worse. However, yes, it was pretty bad. Don't think you can turn this into a Federal Victory.
