_Saturday, May 14._--The rebels are falling back. General Sheridan's cavalry has done great damage in their rear. Our fourth detachment received a rebel gun to-day, in place of the one lost on the tenth of May. Two more guns and caissons were taken from the enemy to-day. A mortar battery was playing on the enemy's lines all day. Rainy weather.
_Sunday, May 15._--Our battery left at half-past one o'clock in the morning, marching but a few miles. The Second corps was relieved by the Eighth, General Augur, being in reserve for a few days. We rested all day. A heavy shower fell in the evening.
_Monday, May 16._--Remained quiet all day. It was read in line that twenty-three thousand men, reinforcements, were on the way.
_Tuesday, May 17._--All the batteries were reduced to four guns. The guns of our left section were sent to Belle Plain, by way of Fredericksburg. We changed camp at four o'clock P. M., and again about six, and marched off about ten o'clock in the night, going to the right of the line.
_Wednesday, May 18._--At daybreak, heavy fighting commenced on the right. Our battery was in position, but as reserve. Generals Grant and Meade were in front of our battery, watching the progress of the contest, which was fought almost precisely where the great assault of the twelfth instant took place. Battery B, Rhode Island, was in action. Many of the new troops, the Corcoran Legion amongst them, took part in this fight. We returned to our camping-place in the afternoon.
_Thursday, May 19._--Near Spottsylvania Court House. We changed camp at eleven o'clock A. M., going in front of the army headquarters, and were pleasantly situated on the edge of the woods. A little after three o'clock P. M., great excitement prevailed on the line, the rebels being reported to have made an attack on the Fredericksburg road. Our battery was ordered out, going two miles. The fight was nearly over at our arrival, the enemy being driven back. We returned to the camp with orders to be ready to march at eleven o'clock P. M. The battery remained packed up all night, but did not leave.
_Friday, May 20._--Near Spottsylvania Court House. Quiet all day. Started at eleven o'clock in the night. The battery wagons were all uncovered. We marched all night.
