[Colonel E. M. McCOOK:]

COLONEL: The general says have your transportation in readiness to go. He cannot tell whether it will go or not until he goes to headquarters. He is just starting. If you march you will take every soldier with you except Colonel Hoblitzell's regiment.

I directed you in the note this morning to draw in your pickets. Notify General Steedman that you have withdrawn the troops from the island, and, if you have other patrols out, notify either him or General Whitaker that you withdraw them this morning.

Respectfully, yours,
