_Sunday, September 1._--Col. Geary received three hundred additional men for his regiment.
_Monday, August 2._--Orders arrived for our remaining section to unite forthwith with the rest of the battery at Darnestown. The morning was beautiful. The battery got ready to march. Col. Geary had his regiment drawn up in line. The whole regiment presented arms as we passed by, they being greatly attached to us, while we gave nine cheers and a Narragansett for Col. Geary and his brave regiment. This day's march will always be a pleasant recollection for the surviving. Our road was leading through the most beautiful parts of Maryland. Late in the afternoon we arrived at Darnestown, and united once more with the rest of the battery, after having been parted for three weeks. Gen. Banks' headquarters are there, and all the troops of his command, lying around the town. We had a very pleasant camp, but should not enjoy it long.
_Wednesday, September 4._--After returning from a battery drill, orders awaited our section, in command of Lieut. J. A. Tompkins. We left Darnestown at five o'clock P. M., going at a fast rate towards Great Falls, a distance of ten miles. At our arrival we found the Seventh Pennsylvania Regiment, commanded by Col. Harvey. During the day the enemy had some pieces of artillery in position, to bear on the water-works at Great Falls, and on the Seventh Pennsylvania Volunteers, firing a hundred rounds. Only one man was wounded. Col. Harvey guided our battery through the woods at midnight. Our section took position on the edge of a knoll, while the Seventh fortified our guns. It rained during the night.
_Thursday, September 5._--At dawn of day, contrary to our expectations, the enemy did not open on us again. Having had no food since the day before, some of us went to the town, and as fortune would have it, found bread, molasses, and that renowned coffee kettle, the fourth detachment will well remember. We enjoyed a good soldiers' breakfast. Lieut. Tompkins, behaving towards the men like a gentleman, they would have done most anything for him. In several cases he relieved our wants, out of his own purse. Late in the afternoon we left Great Falls, marching towards Seneca Mills, as the enemy made various demonstrations up and down the Potomac. Rain falling incessantly, and passing through dense woods marching became a matter of impossibility, and it was decided to halt by the roadside until daylight. An unoccupied house being close by, we all took possession of it, and found ourselves quite comfortable.
