Report of Major Elisha S. Kellogg, First Connecticut Artillery, of operations June 22-July 5.

CAMP NEAR HARRISON'S BAR, VIRGINIA, July 5, 1862.

SIR: I have the honor hereby to submit the following report of the batteries under my command from June 22 to July 5, 1862:

In compliance with your orders, Battery F, consisting of fiver 4 1/2-inch Rodman guns, with 250 rounds of ammunition, left White House for camp near Gaines' Mill on the evening of June 22. After proceeding about 5 miles the train was halted for the night on account of the bad road and the extreme darkness, but at daylight it was again in motion and reached camp at 2 p. m. June 23. At 7 p. m. of the same day it was moved to the earthworks already prepared for it on the bluff in the rear of Mr. Hogan's house, subsequently designated as "Battery Porter;" was placed in position during the night, and at 6 a. m.

The firing from both batteries continued at intervals until about 4 p. m., when the
