Dec 22 1861 Wrote Capt. Kelton, “On the 15th I reported that I had directed Capt. Hillyer, Aide de Camp, to proceed to Chicago and investigate charges of fraud made by the Chicago Tribune against the Quartermaster or his Agt. in the purchase of lumber for this command.
“Herewith you will find all the evidence adduced together with Capt. Hillyer’s report.
“It proves a state of facts that in my opinion, should lead to a full investigation of all the disbursements made at this place, from its first establishment as a Military post. As there has been but little actual cash paid, upon purchases and contracts made here, all overcharges against the Government, might be yet corrected and dishonest agents disappointed in their expected profits.
“I have not arrested Mr. Wilcox, as was my first inclination upon seeing the evidence against him, because I have no place to keep him except the Guardhouse.”
