reported to be captured almost entire; also, the Fifty-eighth Massachusetts and Second New York Mounted Rifles, and the Second Maryland Volunteers are almost entirely captured, besides several hundred of killed and wounded left upon the field. The line from which we advanced this morning is so weak that it is in great danger. I beg leave to call the attention of the commanding general to the fact that my division is reported as nearly annihilated, and cannot therefore possibly reoccupy the position from which it advanced this morning.

Very respectfully, your obedient servant,

ROBERT B. POTTER,

Brigadier-General.

P. S.-General Griffin sends me word that General Bartlett fell into the enemy's hands. My brigade commanders report that a very small proportion of the wounded were removed from the field.

General BURNSIDE:

Humphrey succeeded in forcing the rebel pits to the left of the crater. Is now working still farther to the left up the [sic] with the left portion of his brigade. I supposed Warren would attack, but of course without authority for thinking so. Hartranft is in same pits with Fourth Division.
