General SEDGWICK:

The movement of troops which I reported as threatening my position at the bridge seems to be what I have just mentioned in a note to you-to mask their flank march in the hollow just beyond the Bowling Green road, in front of Brooks. It shortens their march very much.

BALLOON IN THE VALLEY,

April 30, 1863-6 p. m.

General SEDGWICK:

The woods directly opposite our bridge on the left full of rebel troops. The extensive camp still remains 6 miles directly south from this point, and a small camp southwest from this point, about 7 miles distant, and I should think a small camp west of this position about 6 miles.

The troops remain in about the same position as yesterday.

General SEDGWICK,

Commanding Left Wing:

I have just explained what I thought threatened my bridge-heads. i do not know whether their troops are moving up to Fredericksburg, or were being massed to move down the ravine between me and Brooks to-night. It is possible, if they were in there last night, as reported by my pickets, that they may contemplate a movement of this kind. Did Brooks' pickets remain all night at the burnt house-Beman's-and had he any men in the ravine?

Yours, &c.,

JOHN F. REYNOLDS,

Major-General Volunteers, Commanding.

Major-General BUTTERFIELD:

General Reynolds is satisfied that the enemy have not weakened their force either in infantry or artillery, and that a demonstrations will bring on a general engagement on the left. General Brooks thinks the infantry force in his front is undiminished and strong. He can see nothing of their batteries.

General SEDGWICK,

Commanding Left Wing:

Please have Hunt telegraph if he can spare a 20-pounder Parrott battery. I would prefer it to the 3-inch sent, as it will opposed by
