Cincinnati, May 26, 1861.

Colonel IRVINE, Commanding Sixteenth Regiment O. V. M., Bellaire:

CoLONEL: I have to-night telegraphed you to cross to Wheeling with your command and support a forward movement to be made by Colonel Kelley. As Colonel K. has been mustered into the United States service, you will please report to him with your regiment for duty, and follow his instructions. I am sure, colonel, that I can rely upon your giving your full and cordial support to this advance, and that the reputation of the Ohio troops will lose nothing in your hands. Please be careful to preserve the most rigid discipline, and do all in your power to strengthen the Union sentiment.

very respectfully, your obedient servant,

GEO. B. McCLELLAN,
Major-General, U. S. Army, Commanding Department.
