Colonel N. B. SWEITZER,
Commanding Sixteenth New York Cavalry:

The major-general commanding directs me to inform you that the object of your expedition is to rid the section of country in which you operate of detached bodies of rebels named guerrillas. In the event of your meeting a force of these people you will offer them under a flag the terms granted to General Lee's army by the order of Lieutenant-General Grant, U. S. Army, accepting the surrender of that army. If they refuse the terms proffered they will of course be attacked and captured or destroyed if possible. Blank parolees and general orders specifying the course to be pursued in paroling are forwarded by Major Waite, Eight Illinois Cavalry, acting assistant inspector-general, at these headquarters, who will accompany you. The major-general commanding directs further that you take means to prevent pillaging and robbing or straggling by your people. No property, excepting that held by the rebels in arms which cannot be brought in by you, will be destroyed. You are expected to embrace in your operations the entire Northern Neck. These headquarters will communicate with you at Boyd's Hole.

Very respectfully, your obedient servant,

J. H. TAYLOR,

Chief of Staff and Assistant Adjutant-General.
