_Wednesday, April 22._--Our battery was paid off for four months service by Major King.
_Monday, April 27._--Received orders at eight o'clock P. M., to march in the morning.
_Tuesday, April 28._--Reveille at two o'clock in the morning. Left camp at six o'clock A. M. We were attached to the Third division under General French. The Second remained behind. We marched six miles towards the Rappahannock; halted at mid-day, and camped in the woods. The pontoon train passed by in the evening.
_Wednesday, April 29._--Marched again at two o'clock P. M., and went to camp at dark three miles from the river. Rainy weather.
_Thursday, April 30._--Our cavalry has crossed the Rappahannock without opposition. The pontoons were laid. Before crossing an address of General Hooker was read in line, to the effect that the Twelfth and Fifth corps had turned the enemy's left flank, by crossing the Rapidan at Germania Ford, compelling the enemy to fight us on our own ground. Our battery crossed at five o'clock P. M. After marching four miles further towards Chancellorsville, one hundred and sixty prisoners passed by. The troops were highly elated at crossing the Rappahannock so easy, as the shore was strongly fortified, and by nature well-adapted for defence. While marching to Chancellorsville in the moonlight, Joe Hooker and staff passed by, and the rumor circulated, all at once, that Fredericksburg was taken, and the rebel army in full retreat towards Gordonsville.
_Friday, May 1._--The battle opened about ten o'clock A. M., near the Chancellorsville and Fredericksburg Plank-road. The First and Second divisions of the Second corps, commanded by General Couch, formed at two o'clock P. M. Our battery advanced about a mile. Going down a hill we were suddenly received by one of the enemy's batteries, whereupon we countermarched to the top of the hill, going in position immediately. General Sykes' division of regulars fought bravely in front of us, till they had to fall back on our battery, we kept up firing for some time, until General Hancock arrived, informing General Couch that his position was completely outflanked, and that he had better withdraw. The very minute our pieces were reversed, the command, "fix bayonets," could plainly be heard from the rebel line of infantry in the woods. We left at double quick. Our whole line fell back to the tavern. At that moment, the Third corps, under command of General Daniel Sickles, advanced in line of battle, doing good service. Our battery retired to our former place of rendezvous. The fight continued until seven o'clock P. M. Splendid moonlight night.
