WAR DEPARTMENT, Washington, September 23, 1862.
Major General LEW. WALLACE, Columbus, Ohio:
Your letter to the Adjutant-General was received this morning. Efforts have been made to obtain funds to pay the paroled troops. A special paymaster will leave here to-morrow with money to pay them. We have no tents. You must cause temporary sheds to be erected, which can quickly be done. Arms will be supplied as soon as your force is organized. You will issue clothing which you say is on hand and take whatever measures are proper to provide for the comfort and health of your troops. If anything is needed from this Department inform me. The Adjutant-General was recently at Camp Chase but made on report of anything being lacking for the accommodation of the prisoners sent there. The delay in payment has been unavoidable. You will please report whatever in your judgment the service requires to bring your men into proper organization and discipline if there be anything not mentioned in the letter received this morning.
EDWIN M. STANTON,
Secretary of War.

COLUMBUS, OHIO, September 26, 1862.
Honorable E. M. STANTON:
Do not send any more paroled prisoners here. It is impossible to do anything with those now in Camp Chase. They generally refuse to be organized or do any duty whatever. Every detachment that arrives only swells a mob already dangerous. The Eastern troops are particularly disinclined to the Indian service. Let me have time to do something with those now on hand before the task thickens.
LEW. WALLACE,
Major-General.
