Memorandum About Indiana Regiments.

Washington, June 11, 1861

The government has already accepted ten regiments from the State of
Indiana. I think at least six more ought to be received from that State,
two to be those of Colonel James W. McMillan and Colonel William L.
Brown, and the other four to be designated by the Governor of the State
of Indiana, and to be received into the volunteer service of the United
States according to the "Plan of Organization" in the General Orders of
the War Department, No.15. When they report to Major-General McClellan in
condition to pass muster according to that order, and with the approval of
the Secretary of War to be indorsed hereon, and left in his department,
I direct that the whole six, or any smaller number of such regiments, be
received.

A. LINCOLN.
