The battery remained in this position without firing until 9. 30 a. m., July 2, when occasional shots were fired at small bodies of the enemy's infantry and cavalry which were maneuvering in the skirts of timber from 1 mile to 1 1/4 miles distant until 4 p. m., when the enemy brought a number of 10 and 20 pounder Parrott guns into position in the open field about 1, 400 and 2, 000 yards distant, and opened a vigorous fire upon the position. To this fire the battery replied, and, with the assistance of a battery on its left, reynolds' and Stevens' batteries on the right, the enemy's guns were silenced in about two and a half hours' firing., The battery fired occasional shots into the position of these batteries until about 7 p. m., When it was relieved by Captain Ricketts' battery, and ordered by Colonel Wainwright to report to General Tyler, commanding Artillery Reserve, to refit and fill ammunition chests, one gun having been dismounted late in these day's engagement, I was again ready for action by 11 a. m., but, receiving no orders, the battery remained in General Tyler's camp until the 3rd instant.

This battery soon ceased or withdrew. The infantry appeared, approaching over the crest of a hill about 1, 000 yards distant.
