GENERAL: The major-general commanding has left for the scene of operations above. I have received the following report from Professor Lowe, who has been instructed to get all the possible information of the enemy's movements from the balloon:

CAMP NEAR FALMOUTH, VA., April 28, 1863-9 a. m.

GENERAL: I am sorry to state that the wind has been so high thus far this a. m. that I have been unable to ascend with the balloon. The first opportunity shall be improved and reports made. A heavy storm is apparently near at hand.

Very respectfully, your obedient servant,

T. S. C. LOWE,

Aeronaut.

Signal officers have been directed to be givilant and watchful and to report everything. I shall keep you fully advised of everything that is reported here. Have you any wishes or commands?

I am, very respectfully, your obedient servant,

Major-General and Chief of Staff.

P. S. - The night before last, April 26, Rodes' (D. H. Hill's) division had not moved; A. P. Hill's and Trimble's also; and there are no signs of a move. This from deserters who have just come in.
