_Saturday, May 21._--Forced march of the Second corps. Crossed the Mat river at seven o'clock in the morning, struck the Fredericksburg and Gordonsville Railroad, and entered Bowling Green at noon. A fair-looking town. Nine thousand of our cavalry and horse artillery passed through early in the morning, scattering the militia of the place. Marching further, we arrived at Milford Station at five o'clock P. M. This is an important railroad junction, with a good depot, and many dwelling houses. Our cavalry and horse artillery occupied the surrounding farms. At six o'clock P. M., we crossed the Mattapony river, over a stationary bridge, going in park for the night. About seven o'clock the rebels ran out two guns, firing on our camps for a short time. We marched twenty-five miles to-day.
_Sunday, May 22._--On the Mattapony river. We advanced but one mile, at seven o'clock A. M., taking our position in the line of battle, and fortified at once; but, after finishing the works, we had to give them up to another battery, and dug a new line of intrenchments about one hundred yards off. This created great dissatisfaction among the men. Heavy firing was going on to our right, some ten miles off. An attack from the enemy on our corps was expected, but we were not disturbed.
_Monday, May 23._--The Second corps was in motion again at daybreak. After marching ten miles, we crossed the Pole Cat Creek. About noon we arrived in the vicinity of the North Anna River, the Fifth corps being there already. After an hour's rest, our right section was ordered to advance, taking position behind a narrow strip of woods, in front of the river. The rest of the battery, and all the other batteries of the corps, came soon after, and went in position. At three o'clock P. M., a desultory fire was opened on the enemy's works, ceasing by five o'clock. The right section was ordered to go in advance of the line of battle, in front of a strong redoubt of the enemy, and to open furiously, and be a signal to all the batteries of the corps. The enemy offered great resistance for some time. If it had not been for a few very large trees in front of our position, we would have lost a number of men. A heavy cannonade was kept up until dark, when our assaulting columns carried the works at the point of the bayonet. The right section having expended all ammunition, filled up at once and crossed the Creek; being the first artillery on the other side of the North Anna River. We went in position, fortifying during the night.
