Telegram To Governor Yates.

War Department, Washington, D.C., August 13.1862. 8 A.M.

HON. R. YATES, Springfield, Ill.:

I am pained to hear that you reject the service of an officer we sent to assist in organizing and getting off troops. Pennsylvania and Indiana accepted such officers kindly, and they now have more than twice as many new troops in the field as all the other States together. If Illinois had got forward as many troops as Indiana, Cumberland Gap would soon be relieved from its present peril. Please do not ruin us on punctilio.

A. LINCOLN.
