22nd. Up at 4. Rain froze as it fell. Awfully cold. At 5:30 “To horse” sounded. Soon a yell went up near the 2nd Brig., then a few shots. We were ordered to mount immediately—did it. A line could be seen on a distant hill. A few men came up within a few rods of camp. We moved to the flank, came front into line, my Batt. 1st in advance. Threw out skirmishers. Firing commenced immediately and we advanced, firing. Rebs run. Captured two and killed two. The command proved to be Rosser’s Div. which came in from the back road and from the flank. Charged the 2nd Brig. and drove it. Passed to the rear and captured several ambulance horses. Result was 30 men killed, wounded and missing on our side. 22 men captured from rebs and 10 killed. One of H Co. sabre cut, and one horse killed. Moved back and camped at Woodstock. 2nd on picket. Small force of the enemy followed. Skirmished till dark.
