for their attention to duty and coolness in action. My casualties are very slight-2 killed, 14 wounded, and 13 prisoners.

I am, very respectfully, your obedient servant,

Lieutenant T. G. BEAHAM,

Acting Assistant Adjutant-General, Reserve Corps.

HEADQUARTERS SECOND BRIGADE, North Chickamauga, October 10, 1863.

GENERAL: According to promise, I send you a map* of the left part of the battle-field and the country as far down the Chickamauga as Mission Mills. It is taken off the basis of one of the engineer maps furnished me. The roads and situation of houses on that map are in many places corrected, while many other roads are added, and corrections made in the range of Mission Hills. The position of the rebels upon the night of the 18th is partly taken from what I saw, and partly from reports of prisoners and correspondence from Southern papers. You will find it very rough, for I only have one pencil, but in its main features correct. If referred to General Thomas, he can correct any little inaccuracies or place the line Sunday.

I am, very respectfully, your obedient servant,
DAN'L McCOOK,

Colonel, Commanding Brigade.
