Honorable SIMON CAMERON,

Secretary of War:

Please answer my inquiry of yesterday at once. It is very important.

O. P. MORTON,

Governor of Indiana.

WAR DEPARTMENT,

May 3, 1861.

Governor OLIVER P. MORTON:

DEAR SIR: I am in receipt of your letter of the 27th [28th] ultimo, giving this Department a very full account of your action in response to the requisition made upon you from this Department for troops, and I beg to tender you the thanks of the Government for your very prompt and efficient action.

It gives me pleasure to inform you that a large supply of artillery has just been ordered by the General-in-Chief to be sent to Major-General McClellan at Cincinnati, which it is confidently believed will be all sufficient to command the Ohio River. Every effort, I beg to assure you, is being made to provide ordnance supplies, but it is impossible to distribute them properly unless requisitions are limited to the actual wants of the troops called into Government service. The number and kind of troops for which supplies are required should be stated in each requisition, and evidence also given that they have been mustered into service.

It is contemplated to make another requisition for additional troops, to be mustered into service to serve during the war. As soon as determined you will be informed of the number desires from your State, which I trust will be in a day or two.
