Marched next morning at daylight to Orange Grove, and went into position, where the battery remained until 1 o'clock next morning. Marched that day to Robertson's Tavern, and encamped for the night. Remained in harness all next day. The battery was ordered to march next morning at daylight to the right of the line. The battery remained there all that day until 4 p. m., when I received orders to proceed to camp, where the battery had been the night previous. Received orders that night to report to General Tyler next morning at daylight. I reported to General Tyler, and he ordered the battery to proceed to Culpeper Ford. Arrived at Culpeper Ford, and encamped for the night. Marched next day at 2 p. m., and arrived at Mountain Run at 8 p. m. Marched next morning at 8 a. m., and arrived at camp near Hazel River at 3 p. m., on the 3rd instant.
