Colonel GEORGE W. DEITZLER,
Acting Brigadier-General, Fort Scott, Kans.:

SIR: Immediately on receipt of your express dispatch, dated 26th instant and received but an hour since (12 m.), I have directed the concentration by forced marches of the following troops at Fort Scott, where they will report for duty.

Colonel Doubleday's brigade, consisting of Second Ohio Cavalry, Ninth and Twelfth Wisconsin Infantry, also First Kansas, now at Lawrence, forming portion of your own brigade.

The orders to these regiments to move by forced marchese were peremptory, of which copies will be sent as soon as possible, and should any of the regiments fail to report within due time you will not fail to hold the commanding officers to their strict military responsibility.

Should you require the services of Colonel Jennison's brigade (he ranking you), you will use your discretion in sending for him if you think it necessary.

I will endeavor to send you a field battery at the earliest possible moment, as I am organizing it now.
