HEADQUARTERS ARMY OF THE POTOMAC,
September 30, 1864.

General HUMPHREYS:

Refugees yesterday from Petersburg bring information very reliable that Rosser's brigade of cavalry has gone to Early, and also that the following brigades comprise all the cavalry south of the Appomattox: Davis, Dering, Barringer, Young, and Dunovant. Rosser went over the Appomattox last Monday night. Two deserters from Eighteenth North Carolina, Lane's brigade, Wilcox's division, came in at sundown last night. They report that all of Wilcox's division (the three brigades in our front) were packed up and rationed, and under marching orders; had not moved when our informants left, but were to move during the night. Cooke's brigade, of Heth's division, was to have relieved Lane's yesterday, but got into fight with our cavalry, and could not relieve it; are mining on the line occupied by Seventh North Carolina, Lane's brigade, informants say, to blow us up. This is on the extreme right of their line of infantry three-quarters of a mile form Davis' house (burned) on Weldon railroad.

Respectfully, your obedient servant,

J. C. BABCOCK.

(Forwarded to General Warren.)
