Colonel GODDARD,

Assistant Adjutant-General, and Chief of Staff:

The enemy are crossing (infantry and cavalry) Chickamauga Creek at Alexander's and Byram's Ford below. Colonel Minty has fallen back toward Rossville; has two of my regiments. Colonel Minty reports cannonading toward Cleveland last night. This forenoon a column of dust arose in Napier's Gap; three hours in passing. A large camp fire is now seen at Napier's. The column that attacked me came through Napier's Gap; another column came from the direction of Peeler's. Colonel Minty reports infantry flanking him on both flanks.

I am, sir, very respectfully, &c.,

J. T. WILDER,

Colonel, Commanding Brigade.

General McCook directs that you move your command immediately on the main road leading in this direction. Further orders designating your new position will reach you on the way. Orders from department headquarters just received order this movement.

Captain MERRILL:

Southeast 25 miles I see a heavy wagon train moving east to a gap. By the dust, I think it goes southeast through the gap. Has been passing one hour or two, and still continues.
