GROVER'S HOUSE, September 29,1864--8.30 a.m.
(Received 9.30 a.m.)

Lieutenant-General GRANT,
City Point, Va.:

Birney has advanced from Deep Bottom and taken the main line of works at the signal tower, New Market Heights, which commands the road, and is advancing. This lets out Kautz, who is starting. By means of cavalry we have communicated across to Ord's column, who Colonel Rand, of the Fourth Massachusetts Cavalry, reports to have carried the enemy's main line of works in his front and is advancing rapidly. Paine's division took their line handsomely, with considerable loss.

BENJ. F. BUTLER,
Major-General.
