As Oe? Q. A. Gillmore to H. W. Hallecck, October 15, 1863

In the Field, Folly Island, 8. C., October 15, 1863.

Maj. Gen. H. W. HALLECcK, General-in-Chief, Washington :

GENERAL: I have the honor to request that the detachment of the Eighteenth Army Corps now serving in this department be transferred to the Tenth Army Corps. ‘

A part of the detachment has been in this department since February last, and the regiments are now more nearly identified with this command than with the one to which they belong.

The period for which these troops are likely to continue as part of this command seems to be quite indefinite, and for all the purposes of administration their consolidation with the corps organization of this department is desirable. i

The Tenth Corps has lost several of its strongest regiments by transfer to the Department of the Gulf, and has been much reduced in the late campaign.

The addition of the force above named would scarcely do more than restore it. to its original footing. ——

I inclose a list of the regiments constituting the force referred to, showing their aggregate strength.

your obedient servant,
