. Three men of our
battery rode back to the battle-ground to inter our dead; but found them
already buried by Battery C, Rhode Island. Lannegan was buried near our
camp; also, Lieutenant Cushing, Battery A, Fourth Regulars--this battery
is to be consolidated with Battery I, First Regulars. The great artillery
assault on our centre, was the last effort of Lee's army to force our
lines from Cemetery Hill. The rebels' ammunition must have been nearly
expended after that. Our battery used as much as twenty-two hundred rounds
of ammunition, during the battle. The town of Gettysburg is occupied by
our forces. A heavy shower this evening.

_Sunday, July 5._--Battlefield of Gettysburg. Our army has taken twelve
thousand prisoners. The rebels are in full retreat. Pleasanton's cavalry
and the Sixth corps are in pursuit. Our battery will be consolidated with
Battery B, Rhode Island. We received a new supply of ammunition and
marched off on the Baltimore road, by seven o'clock P. M., going in camp
near Littletown, six miles from Gettysburg, by nine P. M. It rained during
the night.

_Monday, July 6._--Remained in camp near Littletown all day. General
French took a pontoon train from the rebels near Williamsport. The Potomac
reported to be very high.

_Tuesday, July 7._--Marched to Taneytown, seven miles, and went to camp,
on account of the infantry having been without rations for several days.
The Twelfth corps passed through this afternoon. The town is under
contribution of rations for the troops.

_Wednesday, July 8._--Left Taneytown early. Marched twenty-four miles
during a tremendous rain-storm. Passed through Woodsborough and
Walkersville, and went to camp in a field of oats, live miles from
Frederick City. The news of the surrender of Vicksburg were read in line
on the road.

_Thursday, July 9._--Marched at seven o'clock A. M. Passed through
Frederick City, which was guarded by the Seventh Regiment, New York
militia, and a new battery; Jefferson City and Perkinsville, crossed the
South Mountain and went to camp for the night, not far from Sharpsburg.
Near Frederick we saw the body of the spy Richardson, hung on a tree by
order of General Buford of the cavalry. Marched eighteen miles to-day.

_Friday, July 10._--Marched through Kettysville. The Third corps, General
