Honorable SIMON CAMERON,

Secretary of War:

Within one week four infantry regiments, three cavalry companies ready for the field-the infantry, however, being concentrated at Camp Dennison for defense of Cincinnati and to operate in Kentucky. In addition, twenty regiments organized, averaging about one-third full, which will be delayed some weeks for want of clothing, blankets, equipments, &c. To encourage recruiting add a few to commence recruiting in a few days. Cavalry and artillery delayed from same cause-General Ripley's incapability to fulfil his promise to furnish cavalry equipage and artillery harness. It has thrown us much aback since Manassas affair. We have sent into the field infantry regiments, three batteries, four guns each, and two cavalry companies. The encourage recruiting, please authorize me to purchase 10,000 to 15,000 full suits of clothing, to distribute among recruits immediately on enlisting. Give us prompt clothing and arms, and it will add this fall many thousands to the present complement. Would be glad if possible, to give you 100,000 men. You will need to have all.

W. DENNISON.
