In reply I have to say that the only force (one regiment rifles and one infantry, with a section of artillery) of my command as yet armed and equipped has been pushed forward to the support of Colonel Wallace at Cumberland and for the protection of our border settlers in that direction; the other regiments are without clothing, arms, or equipments still, notwithstanding my efforts to fit them for the field. You will therefore perceive how impossible it will be for me, although I much regret it, to comply with your request.

With great regard, very truly, yours,

GEORGE A. McCALL.

After advancing so as to be almost within reach of our pickets at Newport New he changed his course up the James River, and was yesterday encamped at Young's Mills, between eleven and twelve miles from Newport News, near Mulberry Point.

Acting in consultation with my engineers, I have advanced the two
