The whole Army of the Potomac was in our immediate vicinity, under command of Gen. Meade; the Ninth Corps, under Gen. Burnside, reporting direct to Gen. Grant, who was in command of the entire Army of the United States, and was personally directing the movements of the campaign against Richmond, and at this time, May 2d, had about completed his plans to cross the Rapidan and attack Lee's army.

On May 4th, the Fifth and Sixth Corps crossed at Germania Ford, and the Second Corps and Sheridan's cavalry crossed at Ely's Ford; Burnside's Corps was at the crossing of the Rappahannock River and Alexandria Railroad, to hold that position until our troops had crossed the Rapidan.

On May 3d we got everything in shape for a forward movement, and on the 4th moved toward Brandy Station, and encamped near the railroad bridge for the night.

May 5th, broke camp early in the morning, and moved with the corps across the Rapidan, at Germania Ford, and continued our march until late in the evening. Since early in the forenoon we had heard the incessant roar of artillery and musketry in our front, and during the last part of the march had passed large numbers of wounded men going to the rear.

On the morning of the 6th we hitched up at three o'clock, and awaited orders. At five o'clock we started with Benjamin's battery, and marched about four miles and went into position near some woods. There had been a constant roar of musketry since five o'clock. Our position was such that we could see but a very small part of the field, and we wondered why we were put in such a position, as the underbrush in the woods just in our front was so thick that we could not see an enemy until they were right on our guns.

We remained in this position until nine o'clock in the evening without firing a shot. All day long the roar of battle had continued; large numbers of wounded had been passing our position all day; occasionally a stray shot would come our way, but nothing of any account.

At nine o'clock in the evening we had orders to limber up, and moved about five miles out on the Chancellorsville road, and went into camp at three o'clock in the morning.

On the 7th we hitched up at eight o'clock in the morning, but did not move until dark; then we marched by the Chancellorsville House, and at daylight went into camp. From this until the 15th, we remained near this camp, going into position once or twice, but not firing a shot; in the meantime the infantry and cavalry with some artillery, had been having some very hard fighting, but the large amount of woods and the contour of the ground was such that a small amount of artillery was used in the battles of the Wilderness and Spottsylvania, so that on the 15th a large number of batteries were sent back to the rear.

We hitched up at four o'clock on the morning of the 15th, and started for Fredericksburg, where we arrived in the evening, and encamped; remained in camp the 17th, crossed the Rappahannock on the 18th, and next day marched to Belle's Landing, and remained there until the 24th, when we started for Port Royal, where we arrived on the 26th.

On the morning of the 27th we received orders to send forty horses and twenty men to the front.
